What would be the best intercooler to run.Air to air,Liquid to air.I am a machinist and was wondering what everyone thinks.

 

depends on the use of the car. gonna need to give out some more info like daily or track only? hp level? turbo?

 

I am building this car for autocross Bridge port motor and the power is around 500 rwhp and turbo is innovative gt61hp dual ceramic ball bearing q trim.

 

hello anyone

 

your turbo will be too small. I have a gt-40 on a half-bridge ported fd block, it gets spooled like its a toy.

I'd get a greddy r-core front mount if i was you, but thats just my opinion.

 

You’re going to attempt to autocross with a 500 rwhp bridgeported car????? And with a Gt61 Q trim??????????? Good luck with that, lag is your enemy on a autocross course and so is explosive spool up. Its like you’re building a car for the EXACT opposite for auto crossing. Just don't tell us there will be 195 front tires and 335 on the rear.

But for your post question. Air to Air is best for the street or long race courses. Its lighter and pretty darn effient if it gets good air flow and is properly sized. For the ultimate in cool intake temps, go water to air with a reservoir for water and ice. But this is really only good for a drag race, as the water / ice combo will melt eventually and need refilling with cool water/ice. There are air to water intercooler which use a heat exchanger also, but it does not cool as well as either aforementioned methods, it just maintains a steadier temp. For those willing to argue this.. think.. your going from air to water then back to air, physics dictates each time you convert energy from one form to another there will be a loss, now do this 3 times instead of 2.

My $0.02 anyway

sorry i meant to put down i also have a innovative gt66-ball bearing

 

I agree with RacerXtreme7, might want to rethink your set-up or change your event.

 

sorry but you maybe confused with autocross with solo2.a innovative gt 61 is not a big turbo on a bridge port.it should give me somewhat linear power

 

gt61 will spool like a joke. you wont make 500 horsepower.

you will be overrevving that compressor

 

back to the intercooler question perhaps? I'm on the same page as far as loking for an IC setup. My 13B is in a miata, and my rad is 26x16x3, dual-pass. I'm unsure if I will have cooling problems if I usea front mount, and I'm unsure how I can keep the IC setup light and effective for 20-30min track sessions if I go water/air....

 

Turbo 1

Thats pleanty size for a radiator, go front mount and use ducting with a good puller fan behind the rad, you should not have any cooling issues at all. Water to air is heavy and only works better then a optimal air to air if the water used is chilled (ice added). Save your self weight, complexity, space, maintenance, and potentual issues (leaking, bad pump, wiring pump etc) and get a properly sized front mount.
