I have noticed that the NZ 380's (VRX and GT) have 5 kw's more than ours. Does anyone know why?

Different intake ie less restrictive because NZ has more lax noise restrictions than Aus.

Probably the truth... That was the 3rd gen magna difference with us n them

Cool! Now who can get me one? :D

Remove your current air intake and set up a CAI.

i asked the same question and dont think when they say less restrictive intake tract they mean a different snorkle. it must be something else cause i posted a pic of the engine bay of the kiwi 380 vrx and the aussie version and they looked identical. but i could be wrong cause i never did find out. :(

why oh why oh why would you buy a brand new car and then replace factory parts with PVC piping,

maybe on an older car yes, but why on a brand spanker new car for f all gain,

personally i plan on keeping mine stock when i get it engine wise unless factory backed sc's or something along those lines surface

ive learnt my lessons with previous family cars lol

Agree.

More gains are to be had with exhaust. I have a feeling there will be some really worthwhile gains to be made by replacing the third single cat system with a dual system straight off the headers.

Its from the very colder weather..:)

What ever is different in the NZ VRX's make s a worthwile gain, at 3000rpm it makes 22kw more than ours, tapering off to 5kw gain at the top end.

Oh I was joking, stupid idea if you ask me. The reason I don't have one.

Its to do with emissions. They have less restrictive laws there and thus their 380s are
tuned differently to ours.

Ahh..

In that case it does look worthwhile. Have you got graphs for comparison or were those figures just in a review/article?

gosh!

when you look at it like that that certain factory inductions can get so much more kw's aty a certain rev range, andc we all know the exhaust is very restricted and can apparently have up to a 20 kw gain , not to mention rpw's throttle body upgrade is ment to be worth while,

then all i have to say is damn! there will be some tuff 380's around in a few years time

Ahh..

Go to the NZ 380 page and download the brochure, it gives the graphs in there, page 14

OK, Graph in thumbnail.

Significantly more power available lower in the rev range.

At 2500 rpm the NZ intake engine is already making 100kw whereas the Oz car doesn't make it til 3200rpm.

Torque is unchanged.

I'm going to contact my Bris dealer and see if I can order the NZ intake. get it installed next service!:cool:

Torque must be changed if there is more power at the same revs

Torque must be changed if there is more power at the same revs

Yes, you're probably right because engine power - KW - is just a measurement of work X time. So torque must be more to make the power?

Also, when you look at the two curves, the ideal one is the blue curve. Maybe this was the original intake from design but had to be modified for Oz once it was realized the emission target couldn't be reached?

omg look at that graph and how the torque just dies off. That shows you how restricted they are. Open them up abit and you could be pulling some pretty decent figures.

if the torque curve stayed flat at 343 all the way to 600rpm readline you would expect 215kw

Increase the rev limit to 7000rpm with the same torque and expect 250kw.

I dont know if this is true or not, but a dealer here told me they had a different exhaust system for the extra power

dunno if this is true or not, but have to say they're pretty loud and very sweet sounding for a factory exhaust (although i havent heard an Oz spec VRX to compare)

The 380's sound piss weak, i'm sorry to say. It's not their fault, it's the restrictive exhaust and intake to meet the strict guidelines.

When i buy my 380 i'll be re-doing the whole system intake to muffler. Won't be for a few years though :P.

Finally found out what the difference in the intake is. Oz 380's get the intake for a 4cyl motor because of noise restrictions. There is also a rubber grommet that attachsthe snorkel. I have been told that if you get the US Galant intake, and remove the grommet it slots straight in, thats what happens to the NZ cars. I will try and find the part number for the US part asap.

You are my hero! :bowrofl: :bowrofl: :bowrofl:

You are my hero! :bowrofl: :bowrofl: :bowrofl:

Yes, yes I am. Part number is MN156778 for the snorkel. From what I can see all you need to do is file open where the existing snorkel enters the front of the air box and push fit the new snorkel. Simple and sweet? I think so. For those too lazy to file the opening, the part number for the front of the box is 1500A064. :cool:

If people are interested in getting the parts let me know, and I will see what I can do through my internal connections.

Pic 1 and 2 are of the standard 380, pic 3 and 4 are of the Higher flow snorkel. You can see the difference in size, (68mm vs 90mm) The TMR380 had the high flow one on it....funny about that.

Count me in for the snorkel and the front half of the airbox! You gotta love internal connections... lol

Um... So... Would you make it out of work with that tucked up under your shirt alive??? :D

I have been informed that they cant be ordered in Oz, only through NZ dealers. So much for internal connections. I won't give up that easily though.

Tucked under my shirt? Or stuffed down my shorts, either way a bit lumpy and uncomfortable. Maybe I should just take a mould off the one I have and run them out of fiberglass? In my spare time....

It does not know 1500A064 though. :-(

You can clearly see where the power difference is.

MBD,

This is great news, I was giving up on the intake - thought it was a myth and really an exhaust difference.
Thanks for pursuing this for us.

Maybe we can get one through an Oz dealer to a NZ dealer?

Looking at the above pic from the US Ralliart Galant, the airbox and intake is shaped differently to that of the oversized 90mm intake as pictured by MaganByDesign

MaganByDesign supplied part number MN156778 however according to the web site http://www.trademotion.com/partlocat...?siteid=213714 this part fits US spec LS, GTS and Ralliart Galants.

Therefore the part number supplied is either incorrect or the US based web site is incorrect or the photo above is incorrect. Someone might need to order the one from the US just to find out the hard way, it appears we can order it, as Australia is in the drop down list. At $17.23 US it shouldn’t hurt to much if it does not fit.

I have changed my mind, I believe it is the same 90mm air intake just the angle its pictured on makes it look different, either way someone needs to order it and check. Either way good work MagnaByDesign.

Quite different to this ;

Sorry about the dirty bay; water restrictions ya know

Guys,

I've sent a request to my Galant parts supplier in California to see if he can supply the parts and get a cost and part number of the front of the air box. I'll keep you updated as information comes back. The only restriction I have is that it has to ship to my USA mail box and then tranship, which can add a bit to the cost but at such a small price for these plastic parts it may be OK. More when/if he replies.

Zarbs

stop it with these performance threads!! im trying to convince myself if i buy one i will only lower it on rims and not mod it at all!!! so seriopusly stop it with the teasing and showing how much promise the 3.8 has!!! GRRR

you never know guys, mitsu saying a watered down ralliart is still a strong possibility i think there is a fair chance it will come out with a better induction since as its been said we have a 4cyl induction piece on a 3.8L

Good news guys,

I can obtain this through the US dealer. He replied with these details:

Is this a Galant GTS 3.8??
If so MN156778 IS $14.00 Air Intake
and #MN18008 IS $71.00 Air Cleaner Housing that the air intake plugs into.

Sounds like the air cleaner housing is one unit complete (given the description and cost). I will contact him regarding the payment and shipping details and get one of each sent. Cheers...

Nice work. The 1500A064 is just the front of the airbox. Maybe they wont sell half an airbox. The standard one can be modded to suit the new snorkel anyway.

The part number for the Air cleaner housing appears to be incorrect as quoted by Zarbs however if you add an extra "0" to make it "MN180008" it is search-able on the site previously noted as http://www.trademotion.com/partlocat...?siteid=213714

The only other potential problem is will the Australian spec air cleaner element be identical in dimensions to the US spec housing. Also will the plumbing on the secondary side of the air cleaner match.

Assuming the image below borrowed from the Mitsubishi 380 NZ brochure is correct a difference should be felt between 2000 and 3000 rpm where most people do their driving.

Ordered the parts from the site noted by s311_bvm. No shipping in the order nor confirmation it has been accepted though ti lists the shipping address in OZ OK. There is a field requesting VIN number on the order form but you can accept responsibility for incorrect parts shipment by checking a radio button...

Zarbs

Just saw this in their policy page:

International Shipping Due to manufacturer restrictions, we are unable to ship outside of the United States.

I expect this order to be cancelled. I will order the parts from my other supplier if this is the case. Cheers...

Zarbs

Makes you wonder why they allowed addresses to put in the form outside of the US. Some things in life are not fair. Good luck Zarbs I hope it works out for you.

I think getting the whole airbox is overkill. The mounting for the airsensor is different for a start. Honestly, you really only need the snorkel, a file and 10 minutes of your time.

While you're there can you order me that MIVEC head? Thanks bud lol

Seriously, we'll have to look into that later on....I'm keener on that than a SC.

4 cylinder intake, WTF?

I just asked my dealer, who are supporting a bit of modding, to see if they can order an intake (only) thru a NZ site.

Haven't heard from thew site as yet but it is not unusual for US sites to forbid export. I can get around it though. I might just go the inlet only at this stage and see if that works OK. Will wait for the response from the site first before going to my other option. Cheers...

Zarbs

I managed to order the snorkel through my local Mitsu dealer! It is being freighted out of Japan and will cost the grand sum of $88. It is expected to arrive in 2 weeks. So we shall see how effective they are very soon...:D

No word from the US on my order and it is in limbo. I'll try to get a reply from them on whether it will ship. I found the pic of the two parts. The airbox is the main body only with all the added nuts, bolts and clips as per the pic. Cheers...

Zarbs

Got this reply from the web site:

Because of the Holiday we won't have these parts until the 4th. We should be able to get them shipped out the sameday.

Seems I will have them later next month but I'll wait until they ship to be sure...

You know it's going to be very interesting when we all get our new intakes what the experience will be.
At the moment if I'm on the hwy and I drop back to third at 100-110 I get a really powerful surge at full throttle and comparing that experience to the red curve on the graph it goes around 95kw to 145kw in one thousand revs.

The 90mm intake will tone that down somewhat but of course give us huge gains 1200 - 4000 rpm.

I wonder what effect a pod filter would make? Because I think the 90mm is still going to restrict the motor.

Could some of this extra grunt also come from your new 1-catless exhaust? I was thinking, your "wasted" mod may not go in vain afterall, if you later fix the air intake (and certainly so if changing headers).
And indeed, all us 380 owners are watching these developments eagerly!

The comment I made was before the exhaust change. I haven't had the car out today but I'll let you all know of any other impressions over the next week or two. I think it will only be subtle (ha, not the noise tho).
Yes, I'm hoping that the 90mm intake improvement will be enhanced with the exhaust mod but that may only be detectable on a dyno. I'll have nothing standard to compare against.
Since the whole exhaust mod only cost me $320 it was a worthwhile experiment and will be definitely desirable for headers down the track.

By the way, the exhaust shop did some enquiries while I was there and Hurricane, in Vic, will be doing 380 headers in a few months time.

...but I'll let you all know of any other impressions over the next week or two. I think it will only be subtle (ha, not the noise tho).
Good to hear the engine is making some better sound now (although standard didn't sound too bad for a V6).

Yes, I'm hoping that the 90mm intake improvement will be enhanced with the exhaust mod but that may only be detectable on a dyno. I'll have nothing standard to compare against.
You could always just take the whole air box out, like we did with the carby air cleaner. I did that on my VL V8 just for fun (didn't we all do stupid things when we were young?), and boy what a sound difference that made. (Just joking about taking the air box out)

Definately, your mod will come in handy with headers later.
There's an exhaust company here in Sydney, Liverpool Exhaust, that make Hurricane Headers. I've heard bad stories of them of late, since they changed owners or something. But I've been there for 2 extractor jobs before with no complaints.

Now that the exhaust is no longer holding back the upper rev range that graph showing the blue line peaking at 180kw is going to be a lot higher. Big torque is there til over 6000 rpm and you can feel the cutout activating after that. The electronic cutout feels exactly like the stock engine at 5000rpm; big reduction in torque and the engine unwilling to rev.

With the extra airflow I predict we'll be looking at close to 190 - 200kw already and I don't think that is exaggerating the effect of the exhaust.

Just got a shipping advice from the US parts site. Now just sit and wait...

Hey guys,

I've just been told by the Parts section up here that MMAL has cancelled my order for the intake because "it is incompatible with the parts listed for this region". **** :angry: Doesn't that force me to use a non genuine part or modification that will definitely not meet ADR's????

Can I piggyback an order with one of you guys? I can pay direct to a bank acc.

Anyone who orders through a Mitsu dealer is going to be at the same risk apparently. Otherwise we need someone who can obtain one thru NZ.

Sorry to hear that Knotched. My parts left San Francisco on Friday night, our time, should be here this week. I've been wondering what the change of the inlet will do to the ADR compliance. As they sell the vehicle elsewhere in the world using the larger intake configuration it can't be a big issue. May be just to get the Euro compliance - like having three CAT's. Haven't seen the NZ brochure/specs so I don't know whether they tout the Euro compliance for that version. I'll post some pics of the change over once the parts arrive...

Zarbs

Got home to find the parts had been delivered. Below are some pics of the comparison and before and after. Too a quick spin up the hill from my home but could not really compare anything as I normally go up this hill in the morning when the engine is cold and today it was after driving home from work in peak hour traffic. I got it up over 2000 rpm and things seem a little snappier. I'll compare it cold tomorrow morning. Also did not notice any greater noise from the change. I'll see how things go.

You'll see by the pics that there is a very large difference in the size of the opening and the snorkel is much larger to accomodate a bigger air volume through the inlet. The Oz model is even smaller as they have a flexible rubber gasket inside the body opening as well. The US unit is a snap in fit with lugs, where as the Oz unit simply uses friction to hold it in place. Taking a file to this opening to make the US snorkel fit might not be the best option but if you were vigilant, as opposed to over zealous, it should be OK.

The front filter body is identical except for the inlet size and the fact that the US body has brass bushes inside the mounting hole grommets as opposed to metal or aluminium in the Oz body. The Oz inlet looks puny in comparison to the US unit. The plastics on the US unit are also heavier with a dimpled effect that probably adds a bit of strength. If you fit one of these there are two 10mm bolts (front and rear of the body) and a rubber grommet on the left rear corner.

Do as I did and the whole body lifts up out of the bay quite easily. The rubber hose with the electronics, to the rear of the filter body, connects to the aluminium inlet manifold. Loosen the clamp on this and slide it forward. Undo the two bolts and dismount off the grommet and the unit swings up so you can undo the two clips and separate the body into two pieces. If you're in a windy or dusty environment, pop a clean rag into the manifold inlet so no dust gets in but remember to remove it when you reassemble (Duh!)

All in all it took ten minutes to remove and fit the replacement. I have some thoughts though:

What effect will the change have on the computer's fuel calculations? Is there a setup in the computer for the NZ model which accounts for this. I know my previous Verada's has selections that had to be made when you repowered the computer from dead (disconnected battery). Anyone know if there are multiple programs in the computer which would account for the different inlet sizes? Would it make a difference? More pics in a separate reply. Cheers for now...

Tried to keep these as small as possible. Hope there is enough details...

Zarbs

There's a HUGE difference in size there! I would be VERY suprised if you didn't notice markedly improved throttle response and low end torque.

And the best part!!! IT LOOKS STOCK! No cop, or RTA inspection could pick it.!
HA i love it! I hope you get the gains you deserve for the effort! POWER to the PEOPLE !!!!!!:bowrofl: :bowrofl:

Zarbs,

That is great! Nice installation guide. Might take a few days of driving to really suss all of the difference throughout the range.
What a difference...

Now thats what I call a proper CAI upgrade. You would get some noticeable gains I'd imagine.

zarbs ur a legend! thanks too s311_bvm. now to find a way to get these parts. if i didnt just buy a momo wheel for the XR6 lol

One thing I did was to check the two sets of filter box parts and the only difference in the casting was that the Oz part had >-0.32.1-< engraved in the plastic inside the box and the US had >-0.32.0-< in the same area almost exactly. The Oz part also has a white ink stamp with the Oz part number (shown in the pic of the side by side comparison). The US part is devoid of any part ID's other than the casting engravings as noted.

Worst comes to worst, the parts get swapped out when the car goes for its regular services. At 10 minutes, turn around, not a biggy. Still, I wonder what difference this part swap makes to the overall compliance of the vehicle especially since they had looked to installing it on the 380 TMR had it ever seen the light of day. I suppose it would need a test of the exhaust emmisions to tell exactly what the impact is on the compliance, if any. Cheers...

Zarbs

I just checked the NZ Mitsu site to see if I could find the spec PDF but they don't seem to have one. Did notice that the model line up includes the SX, VRX and GT only (see pic). The SX lists the same 175Kw as the Australian model but the VRX and GT list 180Kw. Seems the kiwis have the low flow intake on the base model like our entire range. This makes me think that there is little or no difference between the two vehicle setups as they would not find it viable to do two different ones for such a small market like NZ. Correct me if I'm wrong.

Also, the VRX still has the leather interior. Maybe NZ is the clearing house for the unused Series 2 VRX interiors...

Keep an eye on your fuel consumption over the next week or so. Mine is running horribly rich and is in the mid 12's no matter how I drive.
If your fuel consumption on the trip computer changes substantially it'll be one indication the ECU might need recalibration.

I wouldn't worry about ADR compliance. Its not an issue. The reason the larger snorkel wasn't used is because of drive-by noise concerns from MMC. Has nothing to do with ADR.

Wow, fair bit of difference in sizes there.

So is that intake just for the VRX and upwards model in NZ, like, is that the only modification that gives it the extra 5kw?

If so, it would be another attraction to put on a straight through muffler on the VRX aswell like the good old VRX, and that was fairly popular.


I mean, I don't understand the way MMAL has presented the 380 VRX, "This is our sports model, same power output, and weighs more", therefore slower.

Don't you think if someone was buying the "sporty" model they wouldnt mind a bit more noise from a straight through rear muffler and louder intake, I sure as hell wouldn't mind.

That's good to hear.

I had my first day on the road from cold and it does have a more throaty sound during acceleration though it's hard to think back and compare the previous engine noise from just yesterday. First impressions are that the car is a bit snappier and now accelerates better from dead stop and also whilst cruising. I'll follow Knotched's suggestion from the next refill of the tank and see whether the fuel consumption deteriorates. My next service is some time away so I may need to visit the mechanic and have the tune checked. I wonder what a dealer will make of the change if I take to my local Mitsu guy.

For the time and money it seems to be beneficial on first drive but it will take some time to be sure. I have to resist the urge to be a real hoon and tear off at traffic lights trying to test the response but from acceleration at cruise it does appear to have some extra go. More later. Cheers...

Zarbs

Guys,

It has been three days now and I have noticed that my "range till empty" computer reading hasn't changed from the fill I made on Monday, before the change over. Still getting a steady reading of 540 to empty. Not knowing the method which is used for the calculation I am not placing too much hope in the reading. I may be off to Lithgow this weekend and I will get an idea of highway cruise and acceleration, especially heading up from Penrith to Katoomba.

Whilst there is some extra throatiness (is that a word?) I must say that the acceleration from rest seems a little less laboured and more free even if you don't but the boot in. Unfortunately, without any dyno testing, my impressions are just that and it may just be my want for better performance convincing my rational brain that there is a difference. Placebo anybody? Cheers...

Zarbs

Try selecting the mode button for a few seconds until the range resets. You'll hear a beep, beep. It should recalculate.

Unlikely to be placebo, zarbs. With the size difference in the intake opening I would be suprised if there wasn't a significant gain in low to mid range torque.

Try selecting the mode button for a few seconds until the range resets. You'll hear a beep, beep. It should recalculate.
Thanks,

I usually reset at each tank refill so I get a better reading "fill to fill". I'm not too bothered at the moment. We'll see what happens on the weekend. I'll be interested to see what you experience once your set arrives and gets installed. Cheers...

Zarbs

It looks like MMAL has cancelled my order too. Bugger hey.

Refilled the tank yesterday for a total of 520 to the tank. Not surprised in the change given I dragged a 6x4 box trailer to the tip (20 Kms) with a quarter tonne of asbetos sheeting and associated wrapping on Saturday. Half the trip is a steep uphill climb and the 380 pulled it with no hassle. Trip computer dropped 30 Kms on the outbound, uphill, trip alone.

I am getting more used to the change in the power outlays. Low down and mid range around town is much more comfortable. If I boot it like I used to, from lights, it seems to jump away in a fashion that surpirses me. I live close to a NSW police station with a 380 patrol car in their fleet. It got me wondering whether these have the larger intake fitted. Might ask the question, and try to get a look, if I ever go past and the car is outside with the driver close by...

If I got the opportunity it would just be an enquiry. No mention of the use of the intake on our 380's. Simply curious.

Got a ship date/notification yet?

Hoping it ships later today, they have acknowledged the order - wanted to know why I wanted 2 intakes and only one airbox :badgrin:


Type40 will get the second intake (as long as the 07 one fits OK).

:shhhh: Patience, grasshopper..... :)

Hmmm...
Like Zarbs, I'm struggling to feel the difference.
It does have a little more torque and feels 'meatier' down low but pretty subtle. My exhaust is noticably quieter which is weird. It's obviously doing something to AFRs and I can't quantify the change at high revs.
One thing I think has happened is that it has smoothed the power delivery and torque between low revs into mid and high revs. Before I really anticipated the change from 3000rpm in particular, where the exhaust note changed and the engine started to really pull. Now it is smoother. I need a tune :rant: and see the results on the dyno.

I have had conformation that the intake has been sent from the US. So we shall see how i go when its fitted up!

I got to Lithgow last weekend and found that the transmission held in higher gears for longer so there may be a beneficial difference in torque. I agree with Knotched that the ride is much smoother. I'm interested to see dyno results though. Petrol consumption was a little better than I expected and this may be due to staying in the higher gear at lower revs for a longer period. I drove there and back in my usual manner with no obstructions like large trucks in the single lane sections so I think I am getting better consumption. Didn't take any note of the figures though and forgot completely to check the km/100l before refilling and resetting the trip computer. Silly me:redface: ...

Just out of curiosity, are you guys running these new intake systems with a K & N?

Errr :confused: no.

We are just putting on a bigger snorkel into the airbox.

Do you mean replacing the standard paper filter in the airbox?

I emailed Shawn from Philcom re something for the 380 but he said nothing was available yet.

Thats right, I thought you guys would have had K & N filters in the new air box. I've already contacted RPW and they have them ($160 delivered to Sydney). I did also contact about 5 other car parts shops to get a price & they all said that they had contacted K & N and were informed they arent making them yet for the 380. RPW must have some special contacts.

Will the Galant 3.8 L K&N fit our 380, they're way cheaper in the US.
Under 60.00 US Dollars

Sent them an email asking for price.
Will it fit,will it.

If you check out the 'My ride' thread by VRX Boy who has a K & N with the standard intake, he said it helps it rev a little better & provides better fuel economy. Apparently the standard air filter is like a big block of cardboard ie restricting air flow. That got me thinking...the guys who have the new 90mm intakes have stated they're not experiencing overly large gains, perhaps this is because the larger intakes are allowing more air in but the standard filter is restricting it from entering the engine in an efficient manner. Come to think of it, if the standard filter fits in the air box, surely a K & N which is presumably the same size would have to fit too - what do you think? Or, just measure the size of the filter you have now & ask RPW for the measurements of a 380 K & N. What have you got to lose?

Hi guys for those wanting a k&n filter the part number is 33-2285. Your local autobarn can get you one 4 around $125. Iam keen on getting the galant intake but how do i go about it? A workmate of mine is headin to the us in few weeks I might just ask him to get me one over there. So which one is the right part number?

I contacted Autobahn & Rocket Industries & both said they havent got a K & N for the 380 yet. I've just ordered one thru RPW (who have them in stock) for $160 delivered to Sydney.

I live in the Bris Sth and I want the intake too, perhaps we can order and split shipping or something. I have yet measured the 33-2285 intake but i wouldnt mind finding a Shop with one in it to compare, or if the guys with the K&N filter could tell us the model, Maybe the RPW unit is the 33-2285?

Maybe the RPW unit is the 33-2285?

Stuffed if I know how to order the intakes. Help please guys. But if anyone else (Sth Bris)wants one drop us a line, we're pretty keen and will get our order in soon,(as soon as we figure out howlol )
I think just ordering them will be easier than getting someone else to do the running around, though it dont matter, as long as we get em.
More down low torque Boo yeah

Got the Email back from Rocket Industries

Use this link;

http://www.trademotion.com/partlocator/index.cfm?siteid=213714

and order this part no for the intake only -

MN156778 - duct, air cleaner - US$13.78

or for the front airbox assembly as well -

MN180008 - body assy air cleaner - US$72.70

It will cost you a bit above $140 AUD depending on your freight preference.

You're definately Paving the way Knotched, I hope you get all your ECU Prob sorted.:bowrofl:
But I have a question, or two.
1. Would you recommend the intake by itself or go the whole enchilada (airbox too).

2. Will the intake by itself 'look modded'?

3. Will the whole enchilada look neater?

You're definately Paving the way Knotched,

No No No, please credit Zarbs and s311_bvm, they did the hard work. I've just reposted the links.


I hope you get all your ECU Prob sorted.:bowrofl:
It'll happen, just when .....



But I have a question, or two.
1. Would you recommend the intake by itself or go the whole enchilada (airbox too).

Up to you, if you have money to waste like me lol get it, otherwise just file out the opening into the airbox.


2. Will the intake by itself 'look modded'?

No. Its Mitsu part and looks stock - and it is stock! It's the part we should have got :nuts:


3. Will the whole enchilada look neater?

Looks a lot better :badgrin:

I'm going to have to start paying you consultations Fees soon.
Thanks Again.

My missus asked me today "when are u gettin that part for your car". She's the best!

I have had conformation that the intake has been sent from the US. So we shall see how i go when its fitted up!

Hey, you got that intake yet?

Hey, you got that intake yet?
You are going to laugh... I just got the card in the letterbox today and with great delight i went to the PO to pick up my long awaited parcel... Anyhoo, when i got home i opened the parcel like a 10 year old at christmas and when i finally looked at the intake duct i thought to myself "thats not right!" So i looked at the part number and the number on the invoice was the same as the number on the packaging (MN156778) but the number on the duct is MN156779! Bloody hell! :rant:

I just sent them an email so hopefully i get a response soon. Im not too worried about it all but the main thing that could concern me is paying 2 lots of postage.

Need to look at their RMA policy. If the goods aren't what you ordered they should reimburse freight, you'd think.
Damn, that's at least another 2 weeks waiting :(

Maybe you could try taking it into Adelaide Head Office and demanding the right part from their 60 not for sale, grrr..

****... It says "no refund on special orders" :rant: What if they screwed up though? Well technically they didn't... The order was picked correctly just what is in the bag isn't what should be! lol

I just thought i would post up some pics of what i was sent from the U.S. Really i am still laughing because if i don't do that i will burst into tears! :cry: It was no fault of the distributors really... It had the right sticker on one side and the wrong one on the other. Luck of the draw really.

This is the correct part number...

I just opened up my airbox & had a look at the standard air filter - it must be about 50mm thick!! I also noticed there is a rubber seal on the underside front edge of the bonnet that runs directly in front of the air intake when the bonnet is shut, therefore I would presume restricting air flow or causing the intake to draw hot air from inside the engine bay. Just wondering if anyone has cut out a small section of this rubber seal adjacent to the intake to perhaps allow air to flow more freely into the intake?

You sure it's blocking the inlet?

The rubber seal adhering to the bonnet goes over the top and around my inlet; it doesn't block it. I wouldn't cut it unless it is definitely blocking it. In fact I'd get it fixed at yur next service.

A bit more on my experience so far with the 90 mm inlet.
I pretty much have to agree with everything Zarbs has posted so far.
While the inlet doesn't give anywhere near the gain of the exhaust mod I did, it has smoothed the power delivery and ~ 90 kmh and above the car has more response in fifth cruising than before when it was very doughy. Now you can squeeze the throttle and get something useful rather than having to kick back to 4th.

But don't expect any major power gains, it just makes the torque more linear up through the rev range; i.e. before you could feel the engine pulling hard between 3-4000rpm whereas now it feels fairly even from 2500 right up to 6000.

A dyno run will illuminate it all when I get the next one done.

There are actually 2 rubber seals - 1 runs over the top of the inlet and the 2nd one (sits back a couple of mm from the front edge of the bonnet) would run straight across the front of the intake when the bonnet shuts. There is a small hole in a plate just in front of the inlet which I guess would allow some air to enter thru the grill & up into the intake.

Regarding your larger intake, I think I may just wait until Tuesday when I get the K & N & see if I get any improvement with that. When I emailed RPW to order the K & N, I asked if changing the standard filter will cause the engine to run lean/rich due to the change in air flow & Dave said the cars computer will eventually automatically adjust to accomodate the change. You mentioned yours is running rich due to the mods - just wondering if in time, the computer will sought it out negating the need for a tune?

I just went and had a look... b****r me, you're right! (not that I ever doubted, Pete :) )

There is the hole in the radiator front mounting rail and there is also two holes in the bonnet located just above where the intake gets it's air. So the intake is getting quite hot air out of the bonnet interior and much less secondary cooler air from the smaller lower hole.

Hmmm... looks like some more improvement for sure to be had from this. Bonnett scoops FTW! Just joking.

Re the computer; I wish I knew. Initially I was getting 12.6l/100km and today after a drive with 3 adults + child with aircon, around the city in 32C, it is 11.6l/100km. Manual fuel economy - oh, the shame :P !

If it's got a learning mode I'd really like to know because I'm on the cusp of possibly reflashing the ECU shortly. Might have to back off for awhile and wait for more information. Patience and caution is probably a better strategy when there is too much unknown.

So if you've got the air on & the car loaded up and your economy is improving, perhaps the computer has made it run a bit leaner?

The K & N goes in Tuesday so at the same time I am going to cut out a small section of the rubber seal in front of the air intake - I'm not naive enough to think its going to make much difference but it certainly couldnt make it worse.

While the inlet doesn't give anywhere near the gain of the exhaust mod I did, it has smoothed the power delivery and ~ 90 kmh and above the car has more response in fifth cruising than before when it was very doughy. Now you can squeeze the throttle and get something useful rather than having to kick back to 4th.


Ditto...

On the US parts delivery. Mine arrived in a box simply open (no bags) and packed with brown paper wrapping as padding. There were no parts labels on any of the items but the invoice listed everything, with the correct part numbers. I have had a similar experience with the other parts (car bra, iPod adapter and trunk guard) I have ordered from a different supplier in California. Cheers...

One can hope...
It would be too good to be true. The improvement might be more due to the bigger inlet. Anyway, I'll find out in time.

Mine was sealed in plastic bags with Part Nos.

If i get no joy from the US parts supplier then im just leaving it stock. Had a gutfull. I may as well be burning $50 notes. :rant:

I don't think you'll miss much. Also, if you look at the thread on intakes in the 3rd Gen, we might end up with a better custom intake later on.
You could be our guinea pig :D ;) :P

Thats disappointing that you guys didnt get the gains you were hoping for from the larger intake. When I was looking in the airbox the other day, I did notice that the hole at the rear of the box which allows air into the engine appeared quite small. Without wanting to open up a can of worms, is it possible the larger intake is allowing more air into the box but the small entry passage from the box into the engine is restricting the air flow so now rather than the restriction being at the opening to the intake, its at the rear of the airbox? Its just pushed the restriction further down the intake line.

I just cut out the section of rubber seal under the front edge of the bonnet which IMO was obstructing air from entering the intake. Took the car for a spin and I just cant believe this is the same vehicle I bought a month ago...presumably the majority of the gain is from the rear muffler & admittedly, it is a cool day but the car now feels like its fighting the traction control without even trying.

I made it clear I was very disappointed with the performance of the car when purchased but now it is so effortless & responsive its amazing. I gave it a bootful in 2nd and changed up at 6000 but it was still pushing just as hard as what it was at 4000. The K & N hopefully arrives tommorrow (also lowering tommorrow) so I will prob start a new thraed on the air filter. Until then, someone else try cutting out the rubber seal in front of the intake to see if its just the muffler change thats giving me the extra grunt.

That's interesting - I had the same result with the exhaust change only. I'm really glad you are getting a similiar response. It's awesome the difference it makes.

On the intake; when I was replacing my standard duct I found a lower inlet.
This enters the airbox from directly below.Pics below;

I think the gain is definitely there, but it changes the torque curve into something more linear when the exhaust has been modified. That means the wheel spin you experienced is moderated and power is gradual. When you really hook it, it's all still there but with more torque.

I know what you mean with the pipe from the airbox but changing anything around this area is fraught with risk because I believe it will interfere with the airflow sensor. That's a definite risk with the Magnas and I think would be even more sensitive with the 380.

The pics I posted originally showed the oval opening for this but I took it to be a water/moisture drain as it was so close to the front of the chamber. On second glance you may well be correct and the upper intake opening is a wam air intake whilst the lower opening is the cold air intake and mixing occurs in the void of the front of the air box. I'll have to look again at the underside of that inlet to see where it draws the air from. Cheers...

Curioser and curioser...

I went to the CD workshop manual and pulled up the intake diagram. It shows the shape of the lower assembly which has a contoured shape as shown in the attached picture. Looks strangely similar, but flipped horizontally, to the incorrect part they shipped to Type40. From what I can see in through the plastic bag of his photo, there is no inlet slot just pressed plastic contours. Maybe Type40 can expand on the part and describe where the holes, if any, are. The part number on Type40's bag and a check of the US parts site list it as the air intake lower resonator of all things, so it may not pass air at all. Seems like it might loop around to connect to the left side wheel arch or under body area. A cursory check with a torch points to the left side in front of the wheel and behind the left hand fog light. Thoughts? Cheers...

Your AFM is Hotwire not carmon vortex, think commodore style. You can put anything on them, take out the little metal filters before and after the AFM (on the AFM) as your air filter does all the filtering work.

Ah, thnx. In that case, there is a plastic mesh at the beginning of the inlet after the air filter. That might be worth cleaning up.

At the moment, with the bigger 90mm inlet fitted, the car doesn't feel as lively as the smaller inlet did. But it might be just that the power is a lot more progressive. With fully open throttle I might have more hp overall which makes sense with more air. I just don't know. Fuel economy is now less than 1l/100km worse than when it was standard. But I'm not driving it hard either; hate to think my plugs might get fouled. So it is in closed loop operation probably a lot where the O2 sensors can regulate the AFRs.
I'm going to take the smaller inlet with me to Tarren and put the whole lot on the dyno to find out the best setup. That has been delayed now to 24th Oct.

Good work Zarbs! Thats exactly what the part is! Does anyone want to buy it??? lol

I've had the 90mm on for over two weeks now and my fuel economy is getting back to normal - driving hard 11.6~11.7 (flat out acceleration runs!) and under 11 normal.

Today I decided to put the smaller intake on to see if, reversing from the 90mm, the affect would be more noticeable.
I took the car out this morning and did some flat out runs (up to the speed limit :) ) with the 90mm and then came home, mowed the lawn, changed the intake back and went out on the same roads again.
I'm damned if I can tell the difference. With the exhaust mod they both pull like trains, maybe the standard one revs a little bit better to 6000 :shock: .
I'm going to leave it on over the weekend. The only way to know for sure is on the dyno.

Another thing; as I was stuffing around with bits all over the garage floor, I thought why not try pulling out the Type40 lower resonator thingy? There is a nice opening into the airbox from a cooler area from below. Why waste it? Anyway I couldn't get to the bolt near the fog light and thought for my testing should involve only one change at once.

But what about it? What does this mysterious lower reasonator - hereby named as Type40's Folly lol do?
Does it trap heavier dirt particles? Does it reduce the airbox noise?
Can we get rid of it without any ill effects?
Can MagnaByDesign shed some light?

I'll put my money on noise suppression. Being before the filter I seriously doubt it'd make any difference to performance or intake flow characteristics.

pretty sure its mean to hold a volume of air ready for the engine to breathe and keep a crisp throttle response. Don't you want the intake to hold the same volume as the displacement of the engine for ideal throttle response.

Its an acoustic damper. Its tuned to isolate induction resonance at certain frequencies. You can remove it without any issue all it will do is create more induction roar! :D

You do but thats after the throttle butterfly within the plenum chamber not before the T/B.

You can remove it without any issue all it will do is create more induction roar! :D


I'll disconnect it from the airbox (move it forward leaving the airbox with an opening) when I put the 90mm back in and see what the effect is. More roar is what we need :badgrin:

On a more sober note, I bet Mitsu spent tens of thousands on designing this part to reduce the drive by noise by something like 2db. This ADR for noise is just ridiculous; when was the last time you were offended by a modern car's induction noise? Emissions I can understand.

You're getting confused with the purpose of the plenum chamber. A resonator works exactly the same as when you blow over the top of an open bottle, once you hit the right angle it'll start the whistle (the resonant frequency of that bottle). This is due to oscillations within the bottle, the air inside is vibrating, but not flowing. So an engine cannot use this air as there is no way for it to get replaced (single opening).

These chambers are shaped and more importantly sized, to produce certain frequencies as certain RPM points. These frequencies are usually equal to induction noises produced by the motor, but shifted 180 degrees (equal but opposite) so they cancel each other out (hence the noise suppression).

Yeah the noise limits seam to be reducing every few years. Imagine they get real quiet one day, you would have to look around corners allot better when crossing the street (cause you won't heat them comming...lol).

Prius comes to mind when running on electric only.

Hey zarbs,

How is your fuel economy now that you've had the intake for a few weeks?

Mine has definitely improved but I'm not sure whether it's the intake as I've changed so much and keep swapping intakes over :confused:

So Knotched, is it still the case you cant notice an improvement in performance when swapping back to the larger intake?

Ah... it's quite complicated. And subjective; so take it with a grain of salt. When you read this, equate it to the graph -

- Updated 26 Octber - Removed because it was all crap; how embarrassing...


Anyway, I'm going back on the dyno on Wed and will take both inlets. Hopefully will decide then which is really superior.

Also, an interceptor piggy back might "clean-up" the response of the larger inlet and make it definitely the better option. Questions that still need to be researched.
I've become obsessed by the whole bloody thing and wished I'd never seen an alternative....:soapbox:

After numerous times trying to get hold of Rey Reece in the US to get my order fixed i have now decided not to bother. It is obviously not meant to be.

I received an e-mail this morning from Rey Reece and they inform me that it was posted on the 15th of this month. Now its up to Aust Post to deliver the goods... Heaven help me... :roll:

Well... Heaven did help me and guess what i have in my hot little hands??? MN156778!!! Woo Hoo!!! :bowrofl:

Good to hear dave now put it on and feel the difference :noway:

Good show old man, no supercharge that beast of yours :D

Good to hear dave now put it on and feel the difference :noway:
Well believe it or not Joe i can feel the difference! Like Knotched says it smooths the power delivery out in the mid range but i feel it has more sting in the upper rev ranges too!

But the induction roar is the thing... Sounds bloody beautiful! :D

Time for another drive then :D

Geez,:doubt: I had decided not to get the 90mm intake, after all that friggin about Type40 had to do to get his over here. I didnt want to go through that.
But now I have a feeling we are about to see some compelling evidence that I should, or all 380 owners should.:badgrin:



P.S.
I hope that the K&N filters I ordered on Monday arrive today so that they can be fitted in time for the QMD Cruze on Sunday.
I was told by Rocket Industries they were in stock, though a few days earlier the Autobahn dudes rang and said other wise.

Get the 90mm intake.

See my addition in "The Search for Tuning" thread.

I know there is a youtube thread but this is more relevant to the 380 thread than that!

Its off the camera phone on a very deserted road... I really needed 3 hands to do this and in no way am i condoning such foolish behavior! :badgrin:

I got the same story did you order direct from rocket or did you get it from autobahn?

I ordered 2 two from rocket industries @ 99 ea plus Postage. Knotched and I should save a couple o bucks this way.
Rocket said they had stock tho:nuts:

Hrmm interesting think i might need to pop into the autobahn i ordered through and get them to check on that.

If they did have have stock, since I ordered on mon arvo, one might think Knotched and I would be Drag racing by now:badgrin:


Or you could just ring Rocket yourself, They still are the sole importer

A few weeks back I did ring Rocket & they said they arent making them for 380's. Ordered one thru RPW....took about 2 weeks to get delivered & cost $157.

Yeah, I rang rocket first and they said "Nope, not for the 380", so we got the Part # from RPW, and with the airboxes from the galant being mighty similar I searched K&N US and got the same Part # as RPW's, So Rocket stilll don't think they import 380 filters, but they will happily supply for the Galant lol . K&N 33-2285 are about US$60.00 but won't export outside the US to OZ, prolly to protect the sole OZ importer and distributor Rocket, that would be where RPW get theres from. ( and Autobahn, REPCO etc), I might ring Rocket and see if they can source the 90mm intake for us too, now that would be Cool.
Dare I say it took 2 weeks coz it came from Rocket in on the East Coast, was sent to RPW, Then Forwarded to you collecting postage, GST and Profits along the way.

I just ordered the 90mm intake from rey reece. Whats the chances of it arriving here quicker than the K & N did?

ouch! lol

ouch! lol

Yeah, ouch indeed!!! I found out the day after I ordered it from RPW the 380 filter is the same as the US Galant (obviously Rocket didnt know that). Could have got one from Rocket for about $100 & to make matters worse, they are a 30 minute drive from my place.

US 3.8 litre Galant intake, now ordered.
Still need to get colder air in there somehow.

Still need to get colder air in there somehow.

I had a look at the air intake and I don't see where is is drawing hot air from the motor side of the sealing gasket on the bonnet. From the trace wire I fed through the holes in the bonnet the air is being pulled from the front side of the radiator past the bonnet lock mechanism as well as through the holes in the plate directly in front of the air intake snorkel. Looks like it is pulling purely cold air into the snorkel...

Zarbs

Its the two holes above it, in the bonnet itself, that worry me, a nice little bonnet scoop would fix that.

Its the two holes above it, in the bonnet itself, that worry me, a nice little bonnet scoop would fix that.

I have actually been thinking about the potential performance gain from some type of bonnet scoop allowing cold air to enter the engine bay. Rather than a scoop, more like two small (subtle) recessed vents...I guess one of them would have to line up pretty much with the intake snorkel to allow the cooler air direct flow into the intake. What do you guys think, would you expect much benefit from that?

I think there may potential there, the cutaway rubber strip showed results.
It would be better than heated air from the bonnet getting in.
The bad thing is the only way trial is to secure the bonnet part open:doubt: and drive it or Dynoed with the bonnet up:think:

There would have to be scoop out there somewhere that would fit. I'm thinkin modded 1/4 panal scoops/vents. Ideas?

Fair enough....I can assure you there would have to be a significant performance gain before I would think about getting them....I was more interested in peoples thoughts on the idea.

My 90mm intake has been sent so I'm hopeful it will arrive next week (better be the right part). Looking forward to a little more kw.

I'm working on something atm. Let you know how its goes.

Well i can tell you that the car has really picked up torque from the low to middle rev ranges but the mid range has benefited the most. The added induction roar and surge in power at 4000 to 5500 is really what this intake is all about! The noise is really really worth it. You will be revving the car out just to hear the bellow from the intake! lol

Its not 175 anymore... Maybe 190 ish???

Stop teasing me....I want that damn intake now!!!!

Stop teasing me....I want that damn intake now!!!!
Lets put it this way... I didn't notice an immediate increase but as time went on i thing the ecu compensated for the increased air flow and increased the fuel and timing and then and only then did i get the gain.

The only thing i think you will notice straight away is the induction road will be louder. And because of that you may drive it a little harder... Not that there is anything wrong with that!

I order the intake last week, not the front box though. I should handle the fitting OK. After the feedback I am looking forward to this mod, I reckon we are gettin some good gains without much outlay, not that we can mod much, with the warranty n'all.
Puttin away a few 375ml waitin for the 90mmlol

Just got my hands on the 90mm intake. I've got to go out now with the family so fitting will have to wait until tommorrow....

Patience dear boy, patience... :D It will be well worth it. Just done expect immediate gains, give it a week or two.

I have to agree. The advantages come after a couple of weeks to let the system compensate for the new air flow. I am happy with the performance as it is and will wait some time before considering the exhaust change. I am torn between that and the lowering/replacement wheels, especially after seeing the outcome of Blue 380's changes to a 380 of the same colour...

They work really well together.

Hey Zarbs, if your thinking of doing wheels & can afford it, go 19's. I much prefer the look of Type 40 & Knotched and am still considering buying another new set & selling mine...perhaps next year.

Regarding the K & N, I just wasnt happy with the results on mine with the smaller intake. I may still buy another one after fitting the bigger inatke but at least I now know I can get one from Rocket (US Galant) for about $100 so its all good. I am just really glad you guys are happy with the performance of the 380's. I willl probably knock off work a little early tommorrow to get stuck into the filing for the 90mm. I've taken note of what you have all said & will not expect too much straight away.

All things considered, look at the performance gains we've got from these cars at a cost (for me) of $148 for a muffler, $47 AUS (delivered) for the intake & perhaps another $100ish for a new K & N - $300 has transformed the car.

Just fitted the 90mm intake.....if you guys reckon it will take a couple of weeks to get the full benefit well I'm going to be a happy camper because I reckon there is already a difference. Admittedly its a cold arvo in Sydney (17 degs) but the thing is pushing so hard all the way up to 6000 its amazing. I can really notice it come on about 4000.

Couldnt hear any induction roar & didnt appear to make it any quieter like some of you guys have experienced but either way for $47, I'm very happy. Not sure what to do about a K & N now...will probably wait a couple of weeks and see how it goes. Highly recommend to others to do it!!

The only issue I am going to have is that its going to start warming up soon and they never feel as responsive on a hot day so it may be hard noticing much more improvement.

Get another K&N, mate, because seriously, they really work well together. It seems to make a large difference out of proportion to such a small hp gain.

Without going back and reading this thread over again, where is everyone getting their 90mm intake? Overseas from NZ, or here in Aus? I would like to get one if not to hard to get and fit.

You can get it here
http://www.trademotion.com/partlocator/index.cfm?action=searchCatalogOEM&siteid=213714 Part number is MN156778 for the 90mm.
and the fitting is simple, either remove the un-needed plastic from your intake box front, or buy the front half of the intake box too.
The first option is under 50 bucks and takes a little handyman work from you. Go the other way if you want to return it to stock after you move on, there will always be some else who will buy the parts off you if you do.

See page 3 and 4 of this thread for some pics and part #'s
Zarbs fas some good pics on 6 too

OR

Use this link;

http://www.trademotion.com/partlocator/index.cfm?siteid=213714

and order this part no for the intake only -

MN156778 - duct, air cleaner - US$13.78

or for the front airbox assembly as well -

MN180008 - body assy air cleaner - US$72.70

It will cost you a bit above $140 AUD depending on your freight preference.

In addition to what Shoot wrote, you have to set up an account with them 1st which is pretty easy. It cost me $47 AUS delivered to Sydney & arrived less than 2 weeks after ordering. I didnt bother with the front half of the air box, I just filed out the old one which was very easy and took about an hour. There is one bolt in front of the air box and one at the rear (both gold coloured on mine) which need to be un-done in order to remove the air box for filing so you will need a 10mm socket with an extension on it. The 2 plastic screws fastening the air intake also have to be removed.

You will need the part number for the intake which I couldnt find but Type 40 has...what is it Dave??? I can assure you ordering & fitting was a very easy exercise and one well worth it!!

anyone considered the 70mm throttle body that RPW now offer, its up from the 65mm standard butterfly. If you're getting gains from a piece of plastic then im sure 5mm more through the TB will help as well

One word,

Yep, I've been thinking about it and will wait til I have an interceptor first. EZ is going to work on something as well.

I've been thinking about the exchange manifold problem and wondering if enough ppl here would be interested in a group buy of a spare 380 inlet manifold (either from wrecker or new). Then we could just send it around to whoever needs it while their's is modified by RPW.

You will pay a fortune for a new one! I was thinking about modding the one off my old TF so i priced a new one as a spare. I think from memory it was about $600! And that was just for the top half... So i think the 380 one being an imported engine will only be dearer.

Hi everyone. Haven't been back here for a while but it looks like we're getting some good things happening with the 380s finally.

I've now got the extractors fitted up to my dual exhaust & has a very noticable increase in torque & responsiveness low/mid rev range. I have ordered my 90mm inlet & a 70mm throttle body from RPW (K&N already fitted).

Next project is a Unichip Q once I have all the above fitted up.

Are they RPW extractors?

Yep RPW extractors

Thats' great. Are you likely to get it dynoed at any stage? We'd love to see what output the extractors will give us; hopefully crack 200hp ATW.

Yep when I get the Unichip done I will have dyno charts. With what you said you got with the intake & what I heard about the extractor/exhaust setup, I think it will definitly be over 200kw at the flywheel with the computer running 98 octane. Maybe even getting up towards the TMR380 but normally aspirated??
Even now with the exhaust/extractors & K&N the traction control struggles & the front wheels feel like they want to lift off.

Yep when I get the Unichip done I will have dyno charts.

Oops :redface: yes of course :)

Can you post up some pics of your extractors in the exhaust thread?

Sorry I'm harrassing you but there is masses of interest in what you've just done, bud!

How did you go with the repositioning the sensors and have u had any trouble re engine warnings?

You are probably in the same situation as me where the ECU is defaulting to an AFR of 10:1 and we're 15hp down on what is available with an interceptor.

Yeah will get some pics done soon.
The two o2 sensors after the header cats have been relocated to behind the main factory cat. I did about 300km of driving then the CEL came on with no affect to the power output. I have sice reset the computer & done roughly 200km & it hasn't come back on.
Although I haven't done a proper check I think the fuel economy may be a bit worse so yep I think the AFR might be a bit out of whack.

Did the extractors make it much louder or just a deeper note?

Also, I'll ask the question everyone wants to know, how much did they cost fitted?

Also, I'll ask the question everyone wants to know, how much did they cost fitted?

The note is lot deeper & a little bit louder which is cool.

Cost was just over $600 plus frieght & not sure on fitting coz I have been doing an open ended contra with my mechanic on a few things now. He had to take the exhaust off & get the muffler guy down the road to weld in some extra o2 mounts as well as fit them. They bolt straight up to the existing main cat so probably wouldn't take that long to fit besides the extra welding etc.

Another thing; as I was stuffing around with bits all over the garage floor, I thought why not try pulling out the Type40 lower resonator thingy? There is a nice opening into the airbox from a cooler area from below. Why waste it? Anyway I couldn't get to the bolt near the fog light and thought for my testing should involve only one change at once.
Did you ever get back to this? Or anybody else? Curious if this makes any further difference, apart from an induction roar (which is almost good enough on its own if without other gains).

I had a go but the hole is only about half an inch by 1 and a half inches so it did bugger all...

we plug those up when extending the intake on our earlier model stuff. Usually makes it sound different and does **** all.

I believe from what ive read they provide ready air for throttle response or some crap.

After fitting the 90mm and the K&N I don't think its worth it. I'm getting very good throttle response and the only thing better would be a pod filter which is going a bit far for me.

Just received my email, 90mm intake is on it's way as is my 70mm throttle body!!

Sweet as, can't wait to see your dyno figure fooz!

Well hopefully, it would be nice if I could get to that magic number of 300 HP at the flywheel! Should be getting pretty close I'd think, after all it's only 225 KW!

Well hopefully, it would be nice if I could get to that magic number of 300 HP at the flywheel! Should be getting pretty close I'd think, after all it's only 225 KW!
That would be impressive!!! I think Knotched said HP at the wheels is roughly KW at the fly so it should be interesting to see how you go. Hey Knotched, what was you HP output last time you hit the dyno with the 90mm intake?

Its been almost a week since I fitted the 90mm and the car continues to impress me reving very hard all the way to 6000 when I change up - no sign at all of it running out of puff before that. It doesnt feel quite as responsive down low (I think Knotched experienced that also) but perhaps I will have to give the K & N a go to see if that sharpens up the lower end.

Had a check engine light come on briefly yesterday which concerned me a little (thanks for the re-assurance Type 40 & Knotched) but fortunately hasnt come on again.

My last run was ~ 180hp atw with everything except AFRs were 10:1.

That was on the dyno from hell lol

So I think Fooz would be pulling at least that now (based on ChipTorque cars with extractors and no 90mm) and with the 90mm intake to come and the interceptor....?

Re low down response - the K&N got rid of the woolley/doughy feel when accelerating just off idle and cruising with small throttle inputs.

It's nice and sharp now and around town is a pleasure.

My theory is ... I read somewhere that exhaust & extractors presented 25 hp atw on a dyno, you got I think 13 hp from the 90mm?, so plus throttle body lets round it off to 15 hp, as you said probably looking at roughly 15 hp from the computer, so that all adds up to 55 hp at the wheels ..... 55 kw at the flywheel? Soooo 175 + 55 = 230 KW. (306.66666 HP).

Since mine is an auto not a manual I may loose some in the translation but I think it may be achievable! If I don't get that may have to do some more mods!!

What mods would be next? You've done exhaust/extractors, K & N, doing intake, throttle body & chip - I'm guessing after that you are getting into serious stuff like cams, head etc...

........ Cut & shut intake manifold with ram tubes??

On a slightly different note... I have just had an idea. Because i am conservative by nature and want to keep my cats how about a twin system utilising the current exhaust manifolds and cats but having 2 separate pipes running down the middle of the car with an extra cat + balance pipes running to a dual exhaust system much like Foozrcools VRX?

This way the EPA should be happy, i can get a freer flow system and perhaps more power? I had a similar tuned length header pipe system like this on my TF but with a single pipe after the cat and that worked really well. Any thoughts?

Wait til you get a dyno reading - I think it's counterproductive to guess an output. I was really surprised at the big variance between dyno readings.

Cams are definitely the next step. 380s have an advantage, both manual and auto of lots of low down torque. So if we lose a small portion for big gains in the mid to high rev range it will be worth it.

After that it has to be forced induction; but is it worth it if you can make 240kw (flywheel) with just mods including cams?

I think for the 380, big outputs will be achievable quite cheaply rather than FI. For example a couple of thousand will buy you everything we have talked about here versus 6000+ for a supercharger from the US.

Not on a Posties wage i wont be...lol

Hey, quick question. I want to order the intake now, and am wondering how+who is it delivered by? What if there's nobody home when it arrives? Does it get taken to the post office or something?

As im in the "trade" i will and can answer this for you! :D

It is delivered international registered so that means that we handle it. If you aren't home it will be carded to the closest P.O. ( if the postie doesn't like you then it will be the furtherest ;) ) It is a signature item so that means it wont just be dropped at the door and left insecured. I hope this helps!

Yeah, that helps a lot! I haven't ordered stuff this way before (I always prefer to see the item/s "in the flesh" first, but of course in this situation that can't be done).
If I am as impressed with this mod as everyone has been, then I'll go for the exhaust.
PS I do recall your occupation from one of your first posts, so I figured you'd be the one to answer this query.

My intake arrived in under 2 weeks from the date I ordered it at a grand total of AUS $47 delivered to Sydney.

As I (and others) have already done exhaust & intake, my advice would be to do the exhaust first....the gain from the intake is noticable, but the biggest gain is definetely from the exhaust (or in my case the rear muffler). I'm no expert but I wouldnt think the benefits from the intake would be as significant if you are running the very restricted standard rear muffler.

Taken from RPW site....anyone interested living in perth to try???

$220 for a CAI kit??? Why buy that when you can get the Galant snorkel for around $50 landed here? lol

Dont know what they change though. They could be doing a larger more freer flowing intake. Have to wait and see

I noticed that it was dated on the 19th of March this year. If we haven't heard anything by now than maybe it isn't eventuating. Looking at pics of their other CAI's all it might be is some pretty blue or red ducting... Thats a lot of coin for pretty ducting!

ah. fair enough. well in that case you have made my decision easier. i will order the 90mm intake and K&N filter asap . I thought there was a chance they would make something better and i was going to hold off for a bit.

i agree that is alot of money for come coloured intake.

:bowrofl:

Agree with Type40.

If there was another $170 worth of power i.e. 20hp, to be had - definitely. Somehow I doubt it.

The 90mm intake is a proven gain and looks totally stock - which it is - in the US lol

Im sure you have poured endlessly over the posts in this thread about the US intake. I think that for the money spent it provides a good gain, especially teamed with a straight through muffler.

Looking back on it i don't think there is one person on here who thinks the US intake isn't worth the money!

hhmmmm definately.

Out of curiousity is the 90mm intake the factory intake or is it a mod for the galant?

If its original i would hardly doubt a mitsubishi engineer would notice the difference....especially if it has mitsubishi labels and logos over it

Off topic, but...

Seadevil, are you going to post up some pics of ur ride in the "Post ur ride" thread?

Blue 380s are a fav colour in the 380 section ;)

i will soon. i appear to have lost all of my photos i took ages ago. will take some more soon and post them. Air intake is now on order :D
