i have seen for the 380 that the galant and tmr models had a high flow snorkel..... which is just a larger version of the stnadard snorkel.... i have ssen one listen on ebay atm that claims to give 4-8kw gains plus also better economy.... obviously this would make a difference but would such a simple thing make such a noticble difference?????
i was wondering if anyone know either how to modify this to fit a 3rd gen or how to modify the standard snorkel for optimum gains??????
i do not want to go a standard CAI that most people do as i do not want to but my intake down so low...... and i was thinking that this may be a very cost effective modification.......

Sounds like you want to modify the standard plastic snorkel that's already there. You would need a plastic fabricator.

it wont benefit a 3rd gen as the intake is almost the same size. the reason we do it to 380s is that the standard intake is only 60mm hole were the galant intake is 90mm.

They are so different.

Agreed Modify your original. And do some searching on cold air intakes and NZ CAI and you'll find much debate, with varied results. But I have been toying with this idea too. I have the sheet aluminium, silastics, all I need is a good heat insulator. ( and a professional finish)

....so is the intake in the bottom pic more restricting??? :S

no, the stock intake is a good design.

i've wrapped mine in 12mm foil/aircell (foil coated bubble wrap) up to the engine side of the AFM.
still testing air charge temps atm but so far it looks promising if not pretty (atm... will be if im happy with it)

so basically you have insulated the standard air intake in an attempt to protect the plastic from heating up and in turn heating the air inside??? so basically you will have air entering at the outside ambient temp and remaining that through the intake... if it works it would be a cheap & easy CAI.... would love to see the differnce it makes in the temp of the air after extended running.... and also therefore the difference in KW's.......

Ive tried this with a previous car and setup. I used industrial grade plumbers insulating tape. I saw very minimal, if any, difference... plus it looked butt ugly lol

If you are worried about heat on the plastic maybe try a DIY heat sheild to protect it from the engines heat??

The heat of the air isn't going to make a lot of difference, better off saving up for a set of cams.

Every 3 degrees C that you can drop the air intake should be good for about 1hp.

In an NA vehicle, it will only loose significant power when sitting still on a hot day, once you're moving and some air starts flowing into the engine bay, the difference will be negligible.

For forced induction, it's a very important principal, hence why intercooling is almost essential.

so then what is the puropse of using any sort of CAI on a n/a car?????

currently at idle with the engine hot the air temp @ the filter is +10 deg; cruising it is ~+4 deg
i am yet to test inside the plenum but as i said it looks promising
one idea i had was to ceramic coat the intake ducting but im not to sure how fragile it would be.. perhaps ceramic coated aluminium cai ducting be the key

Ahhh i can't believe there's anothe cai thread

A LOT of info there

The Oz 380 intake is restrictive that is why some have fitted the US Galant intake, 90mm vs 60mm or something like that. For the 3rd gens, esp the L and W series, the NZ ones go around the radiator to between the radiator and the headlight and with the splash shield removed, get cold air. Do a search for my setup which retains the normal snorkel and added another pipe that goes to the area the NZ ones do.

so then what is the puropse of using any sort of CAI on a n/a car?????

1) Cost is minimal and it makes you feel warm and fuzzy in the belief that cooler air is going into your engine or just for the sake of making a modification.

2) If the factory intake is restrictive, you may succeed in improving the air flow. This will make the engine more efficient and instead of producing more power, it's actually sapping less power to suck in air and instead drives the wheels faster.

3) especially with older vehicles, they didn't always receive cold air into the intake, so a CAI definitely improved things. I think with engine performance and pollution requirements manufacturers now do a much better job than they used to.

The magna sucking in air from behind the headlight or from under the bonnet lip is quite ok, provided the opening is about the same size as the throttle body. The biggest restriction in the whole system is the butterfly in the throttle body, and who drives on full throttle all the time? lol
Most people do CAI for the noise anyway. But who wants to drive a car that sounds like a vacuum cleaner? lol

The biggest factor in power output is ambient air temperature, drive in 40 degrees stop/start traffic and the engine feels sluggish, drive on a cold winter's night and the engine feels good. Live with it.

I simply removed the first resonator that is under the snorkle, and added a flexi pipe from the hole to the front bar in the lower grill area. i faces forward to collect air. i also saw a GDI Diamante, and they have slots in the plastic that covers the gap between front grill and bonnetlatch, where the standard magna has none. i simply removed half the plastic cover so it still just covers the ugly bonnet latch, but has a big gap that lets air from the grill in to the snorkle. usually the bonnet seals this area, and it draws air from each side. i found that i got improved throttle response, and it sounds great at high revs as you can hear it drawing air from the front grill + the pipe in lower grill.

I pretty much have done the exact same thing (which I have mentioned a while ago in another thread). However, I am wanting to go a bigger tube. Someone suggested a funnel that is cut to the diameter of the tube and faced flush against the lower grill in order to force more air in when moving along, and also to insulate the pipe with one of those silver/foam windscreen covers (and tape). Whether it would make any difference or not I don't know, but maybe worth a try?!...

Screams waste of time/fire hazard to me, seriously just go buy/make your own RPW style one.

Yeah I wasn't sure about the windscreen cover thing either. Still, the flush funnel is an interesting concept, depending on the opening size of the funnel. Probably would do nothing though!

I am a little hung over here but, the venturi effect might help but I would say it would probably just mess with the maf. getting any kind of ram air intake effect means some big speeds.
