Hey guys just a thought,

Would CAI have much of an advantage over the stock air intake (above the radiator)

Say if i cut off the stock air intake about 15 cm from the box itself and ran CAI flexipipe?

Matty

I'm interested to see the replies we get in this thread. Me and my mate have been trying to work out a way to do CAI into my car in a way that will be easily removed and reversible if need while also adding gains over the stock intake.

Basically after doing some reading this http://www.autospeed.com/cms/article.html?&A=0009&P=2 I thought the best way would be to keep the stock snorkel and add a hole on the bottom of the airbox with piping going into that therefore leaving me with the best of both worlds i.e the snorkel and piping. However I rang mitsu out of interest to see how much this box I would be cutting up is worth. $330 I quickly decided that I would no longer cut a hole in that box and I'd have to find another way.

Obviously the easiest way is to remove the snorkel and run piping into the existing hole in the airbox and seal it with some removeable. My concern here though is the loss of low end power which I'm not real keen on it's also not going to be a easy remove job (I want it out whenever I get my 6monthly service)

So yeah I'm really hoping someone has a good suggestion as I'm starting to get a bit stumped. The piping to use is also another issue I know you can grab stuff from bunnings but I don't know if its the best thing for the job. While searching the net I found this site http://www.purplepig.com.au/ which has alot of different tubing but I have nfi what the best type is.

as reference I'll attach a pic of what my mate currently has in his magna

Yeah i think thats where i got the idea from (that photo)

i wanna know if there is gonna be power loss or gain or hows its gonna work as well?

ive got the K&N Panel filter in there atm (widowmaker would be proud)

purple pig is about 20 mins drive from me, i know they are expensive but they will have the rite stuff the bunnings stuff has holes in it so much for keeping the heat out its just aggy drain pipe

May I ask why you got a loss in low end from Cold Air Induction!?

The whole purpose of that mod is for MORE low end!!

ahh ok yeah he's done a good job of it did it all before I had my magna so I never watched. We both have K&N panel filters as well. The tubing he got is some special one with no ribbing etc so something like that from purplepig would be great. I'm nowhere near the sydney branch so really don't know what they have.

Yep the powerloss is what I'm worried about. Apparently there is a tiny loss down low (this is why I wanted to keep the snorkel) but gains above 3000rpm. It's not a huge difference apparently but it can be a cheap gain it's just working out the best way of doing it hopefuly with everyones combined brain power here we can work something out :)

I've read about it a few times. Don't quote me on this but I think it's because there is less initial pressure being pushed into the airbox until you get going. This is caused by a wider opening and longer length of tubing to travel.

That doesnt make sense though.

Colder air = more dense therefore a more effective fuel and air mixture and stronger combustion which = more torque.

Maybe what's happened is that the fuel mixture is a little lean? Perhaps an FPR will correct that and maximise the CAI effectiveness.

It doesnt make sense :?:

Strange that you've read that a few times..because I've never heard of CAI causing a low end loss...it's a mod done for low end. lol!
Oh well..

I believe it's because at a stop your not actually pulling that much cold air vs the stock setup it's not until you get moving that you notice the gains because the increased piping is allowed to breath a hell of alot more. It's only a very small margin but yeah deffinately seen it a few times and my mate confirmed it today.

I would love to know whats the best way to get CAI working without having to cut ya car up.

which is what were hopefully going to achieve from this thread :)

well this is maine, pretty much the ame idea as Blakes. Easy to intsall, and easy to remove whenever you want. e.g. i just had a recent service, took me 5 minuets to take out the ducting and throw the stock CAI on. piece of piss. you notice a nice differncee flying down the freeway too. And it just runs down to my flood light in the bumper, one of the best places to put it. dont need any glue or anything, just have a play for yourself, you cant break anythin. good luck.

ooh does it come with the sexy model as well :p

Ok so just clarify something for me how is the tubing held into the airbox? and also how is it held down at the fog light hole?

good to see you felt gains on the freeway have you noticed any gains/losses at the low end?

with the pod, you will notice poor low gains. pods are not good for take offs, whereas panels are.

I have 100mm air con ducting. It fits right in the airbox, no silicone needed or snything, unless you wanna make a fuss, hehe(its prolly just me). and i pretty much just wedges it in the flood light hole. no worries, doesnt move or anything.

Killbilly's right. It shouldn't reduce anything as cold air is denser. I can't see why there would be a difference between CAI and the stock air intake when the car is idle or starting to move. Realistically, it's all at one atmosphere so the pressure should be the same where ever it is. I'd imagine the stock intake gets air at a similar temperature as a CAI setup. What CAI would have over the stock intake would be it's shape, size and flow path into the intake. Correct me if I'm wrong.

hmm Tiphareth that's deffinately a possibility then very easy to install and remove which is what I want!
Redav yeah as I said I don't have this fitted myself so don't have any first hand experience but I have come across a few reports of drops in low end and as my mate said theres gains above 3000rpm although only small down low there's an even smaller loss the only way I could justify this was the shorter distance the cold air had to travel with the stock setup vs the increased distance with CAI. I will be giving this a go myself when I can find the neatest most efficient way of doing it and fingers crossed there will be no loss cos I just love my low end torque and accelleration :)

I dont want to argue with you Slayer so please don't see it that way.

Just that the stock intake for ALL magnas is pretty shocking.

The air that comes in isnt exactly the coldest air it could get.

So even if it does travel a bit further the result is still colder air.

And of course at idle that's different..but that would be the same with the stock intake too.

The air travelling further shouldn't make a difference really because air is already in the pipe.

Anyway...Im just confused as to why that loss has been experienced. It's not that I dont believe it...of course I do..Im just stumped as to why..lol

I know how you feel, mate. I *finally* got the Lukey muffler this week and have installed the panel filter. I've know what mods I was after but wanted to research the how's, why's plus the other side of the coin. There's plenty of stuff I don't know and always keen to learn. I'll admit that I was either skeptical of mods or worried that I'd loose something somewhere. I guess we're all here to find out the same truths and the experience of a community is what it's all about. I'll be keen to see what you come up with. I've posed a question to Dave from RPW so hopefully he'll fill us in.

Also, is it just me or are NRMA being a little anal lately? I sent a simple question about the change of muffler and how it will affect my policy. They came back with:

[quote:ef0d950355]On behalf of NRMA Insurance, we do not provide our insurance criteria on modifications.[/quote:ef0d950355]

It's just a muffler!!! Heck, the last question I sent was, Can I swap the 3.5 for the 3.0 in my car? They came back saying they spoke to their under writers and it's all fine.

Sheesh!

Guys, I phoned a company in QLD 2 months ago called SS Inductions where they design & manfacture aftermarket cold air induction systems & other related airflow products. They make CAI for Holdens & Ford with good gains. The bloke I spoke to there reckons they are designing & working on CAI for the magna range & hope to have something out by December this year. Give them a call later in the year on 07 5597 2393.

Killbilly it's fine mate I think it's good that we can hear both sides of the story here honustly I'm really hoping your right cos I don't want to lose any low end! but yeah as I said I'm just going by word of mouth so want to confirm things before I go ahead with it.

Redav I'm with NRMA and they have accepted my lukey without a problem here's there guidelines on exhausts.

"With the exception of turbo charged vehicles, an exhaust modification is
generally acceptable, provided it meets registration noise guidelines in
your State"

Sounds interesting tones keep us updated

Okay, here's a comment from Dave.

RE: NRMA. Rang them and the lady said we didn't need to know but if you'd like to list it then that's fine. I did. Figured it would make me sound like an honest kind of guy. Except, that I am :D. Seems as though their left hand doesn't know exactly what their right hand is doing. Anyway, it's all fine.
