Cold Air Induction

[400HP]

I'm thinking of getting a custom box made with the cone filters inside (this makes it legal apparently and stealthier) with a pipe running from the guard up feeding the cold air in.

I would like to know what experience people have with a cold air induction system and if it makes a lot of difference in terms of responsiveness, actual power increase and anything else.

i thought id play with the idea one night, so i cruized the strip, with ice packs in/around my cone filter, and after stop-start traffic for about 1 hr down queen st, i got to the bottom lights turning right, anyway i was in the left lane and he was in the right lane (in a worked gsr), and when the lights went green we both gave it death, any way to cut a long story short i kicked his ass, and he couldnt keep up. And i had 4 people in my car, as did he.

And my cars got about an extra 200kgs anyway from all the stereo.

Weather or not it was from the ice i dont know, but later on that night he kicked my ass in a race. So i dont know.

Im in the process of making a cold box at the moment so ill keep u informed

i made a heat shield from aluminium for my pod filter

i noticed alround better performance, but not much.... although the intake temps have been decreased quite a bit, and the induction noise is loudish now

[Guest INASNT]

i made a heat shield with thick neoprene rubber!

and after a long run i stopped the car popped the bonnet and touched the temp of the pod, it was reasonabally cool to the heat coming from the engine and the temp of the neoprene!

If its intercooled, why the need for cold air intake? Doesnt the coola bring the temp back to around 20deg anyway??? :confused:

It couldn't possibly make all that much difference unless its boosted beyond what the coola can handle. Could it??:confused:

[Guest | hype^ |]

hes talkin about air filter intake..

the intercooler doesnt stop the air filter from sucking the hot engine bay air..

Yeah but why suck in hot air to begin with? Might as well only take cold air in to reduce temps all the way through. And I put a cold air partition in to get the most out of my crappy little factory cooler.

Has anyone cut their standard airbox up underneath and plumbed air up from the front. Considering putting standard air box over HKS pod to make engine bay look more legal

Hi guys, 8 degrees celsius increase in inlet air temperature = 5% less horsepower. So feeding your engine 25 degree (ambient air temp) is worht 15% more power than feeding it with 50 degree air (as in what comes out of the radiator). Simply the cheapest and most effective mod you can make to your car.

yep - when i put the heatshield in the 33 it was noticably more responsive. Felt better in stop start traffic too.

[Brody]

The next question is,

where do I buy premade kits for an r32

[JimX]

I noticed a fair sized power increase after putting my cold air box in. I don't see any reason not to do it, if only for legal reasons.

[TTT]

I tried all combos...

in the end (which is now) I have my standard R32 gsts air box with a TRUST panel filter in it.

I have noticed no drop in top end (which is what people reckon the problem with the standard air box and standard filter is) and the car is a lot more responsive due to the fact that the air it gets is cool air rather than engine air.

If my intercooler wasn't in the standard location, I would have mounted the air box down there.

that way, you get cold air coming in always and there is no engine bay heat to heat up the box.. and believe me, it heats it up.

I've done a few tests with temp probe and digital display that I have...

[WazR32GTSt]

yeah you may as well just start with cold air to begin with i think...

i ran a pipe, albeit smallish, up to the stock box with high-flow panel filter in my car. worked a charm although i have to clean the filter and box more often now than before...

plus its relitavely free so worth it if you're bored!

PS if you are looking to find some pipe, the BEST place is clark rubber - i looked everywhere and this was the cheapest way to get pipe that was free-flowing inside...

[TTT]

PVC pipes from any plumber store is also cheap.

AND they also have pre fabricated bends like 45 and 90 degree bends.

All you need to do is slot them together like lego.

if you're really fussy, you can also get that BLUE glue they use for those pipes.

paint the thing black and you're done.

Once all slotted together, the inside is compeltely smooth.

I've got a short length of pipe and a few bends if anyone is interested and is in Sydney..

Yang.. you want them?

[WLD747]

Well Ive got the stock air box cut up, A pipe running down into the guard where my POD filter is, that is covered with a shield to protect from water.

The car runs much more responsive than the engine bay. The best is cold nights the car just launches.

Hope it helps

Cheers

If anybody requires a box I have 1 sitting at home (sitting in my room for 10mths now). I bought it from UAS for $195 and its your from $50.

Oh and I also wanna swap my HKS Pod for a standard airbox.

benm- damn if only this was posted a week ago i just bought the exact one from UAS shyt hehe

ben...

Ben, will this fit my FMIC?

[C yar]

hey guy, over here in W.A you can get a permit for pod filters.

once you got that and you have a FMIC you can run a 3" mandral bent pipe through your old intercooler pipe hole ( you need to make it a little bigger ) and put your pod filter behind your bumper.. perfect ambiant temp there... and legal cos you have a permit for a pod filter.
