Cold Air Intake... Where to put piping in an r33

[dan_the_man]

Ok, I have a k&n pod filter on my r33 gtst. Its sucking hot air from the engine bay. It has a partion around it to reduce this, but I want to duct cold air from the front bumber. I have a standard intercooler. Has anybody else done this? Where can u get piping through to get to the pod? Would I have to cut holes through metal?

Regards,

Dan

yes I believe you would have to cut holes. If you wait for a FMIC first (if you're doing one) there is a really nice hole freed up.

dan_the_man,

I've got to agree with Steve, do the FMIC, it will make much more difference, then use the hole for the factory IC as the intake for the CAI. Most people tend to use the flexible silver tubing as the intake runner, but can be done with PVC, just spray it to make it look less shit.

See'ya :burnout:

ok thanx

a 3" holesaw will go through the metal in 10seconds. just drill a hole, then feed your pipe through. you can get hose/pipe from any hose distributor, i got mine from IHF in welshpool for $20. black - flexible. cant say it made much of a performance difference but if you want to do it, takes about 15minutes all up

agreed, get a front mount and you can use a right angle pipe from the stock cooler to collect air from the bottom. as i did with mine and works great (tight arse)

bugger... i've got an ARC front mount that uses the standard I/C holes and piping...

i'll have to look at another way!

[Hicks]

Yeah man, I got the same problem. I gotta drill a hole too.

Didn't really wanna have to though, Im sure cops could sticker ya for it.

[GiJOr33]

i think it might be an excuse to get a bigger intercooler with the right piping and a Greddy Plenum

If you've got a big FMIC, does the cold air intake actually have any affect??

[Steve]

Have had a partition done and that definately made a difference, mainly after sitting in traffic or on hot days the throttle response was alot crisper, alot closer to when the car is first started in the morning. A duct, at the cost of only a few dollars, couldn't hurt, and is supposed to give a better top end as well - only to the tune of a few kilowatts but better than nothing.

Just my 0.02c

Steve

[ron]

yeah definitely works!!!

build a partition and some sort of cold air ducts and youll feel the diffrence!!!

[riggaP]

Steve & ron: you both have aftermarket coolas? What boost you guys running??

[ron]

HI,

im a faint harted running 10PSI....tur bo smoking up thats why

. i have a trust cooler, and i think they are the best out there.

ron

[Steve]

I too am a bit faint hearted, just run 10lb standard, but have been known to crank it up to 12.5 (0.85bar) when its a bit cooler.

The reason being, that when in traffic, I think I am getting a bit of heat soak through the coola piping, so she tends to ping a bit on higher boost settings during the day when it warms up. Also waiting on a Z32 AFM so that I can get a better tune, then might try upping the boost a bit more.

Steve

[riggaP]

It don't make a lot of sense to me. If the coola is big enough, it shouldn't matter what temp air is going into it, by the time it gets out of the intercooler it should be around 20-30 deg anyway.... right??:confused:

I think what I'm trying to say is that a cold air intake will only reduce the load off the coola, which isn't gonna produce a real power gain...

[GTS-t VSPEC]

riggaP,

The intake temperature will dramatically effect the temperature going into the plenum, thats why everyone tries to reduce the hot air going in, either via a CAI or vented bonnet etc.

Imagine its a 30deg day, if you have no CAI and engine air goes into the cooler at 45deg, even with a big cooler you wont get the temp down much past 32deg. On the other hand if the 30deg air goes in the temp could go down to 24deg. Although it doesn't sound like alot it can make a big difference, cooler air carries more fuel which means more power, and the car is less likely to ping.

Big intercoolers are great but will not cure high intake temperatures, minimising the intake temperature is the best way.

See'ya:burnout:

[Steve]

The cooler the air the better. If it didn't work no one would do it but the advantages of a cold air intake have been prooven time and again with dyno figures to back it up.

[ron]

totally agreed:D

or we just leave the air alone and put the cooler in the freezer every night and served chilled in da morinig:D jk

guys, as you would saw my thread, i need a new turbo.

do you think i should get a GT28 400hp? bolts on to the stock manifold.

ron

[Steve]

Why are you changing your turbo? What other mods do you have? Where do you expect to be getting spool up? What is the car being used for? What are your future power plans?

sorry to be asking so many questions, but I think it is important to get things in perspective otherwise any opinions would probably be no better than a yes or no answer:)
