Intercooler ???

[TurtleSpeedZX2er]

Allrite all you turbo pros! I got a question for you. I know how an intercooler works but how much cooler does it make it..? any one with an intercooler temp gauge thinngy??

Now for my real queston... I made a home made cold air intake for my turbo system. For me it works pretty damn good. my intake tube to my throtle body was touchably cooler than before. I know that the intercooler has a similar function (make intake air cooler) but if cold air is already being sucked in would it be the same thing??

I got a turbonetics T3 set up @5 psi... Let me know what you think...

u only running 5 psi, that make not much a difference at all
but when u running high boost at 1.4Bar like me(sorry dunno whats the conversion to psi). MASSIVE air and fuel is needed at the combustion chamber(2 liter engine), when the air is too hot, gas expand right? simple physics, but when the air went cold, what happen? "more oxygen at the same density", when u know the engine is basically making explosion and push the piston to make HP. more oxygen give more power. and the intercool is the point to do the job, every 1 degree make a difference. but occationally there is some pressure drop when ur intercooler is too big.
a lot of manufacture made things to cool down the temp in engine bay, e.g. St.May Air dancer, those thermo tape.etcetc

u'll know why after once u saw ur exhaust manifold turn red.
u pop ur hood and u can feel like summer is here..

he's running only 5psi because other than his turbo, his car is completely stock. he doesn't even have an exhaust yet. hey Ed, hurry up and get one!!!

[TurtleSpeedZX2er]

Hoh HOh thats what spring break is for. Does any body know of a good exhaust..? Please no bees in the coffee can ones. im trying to keep the sleeper look and sound. Flowmaster, borlas, dynomax?? n e one?

Ahh ... Intercoolers ...

For an answer about the temperature drop provided by the intercooler, it depends on the size, the location, and the airflow going through it (ambient air flowing through the fins, not the air going to the intake). A really good intercooler in a great location with adequate air flow will cool the intake air to near ambient air temperature. For example, my BLITZ FMIC will cool so effectively that the air leaving the FMIC to around 10 degrees warmer than ambient air.

For the reason WHY to have an intercooler and if it has effects if you have that "cold air" intake, you have to remember that the first contact that the ambient air makes when entering the system is with your VERY hot turbo which is powered by very hot exhaust gas. And before it gets into the combustion chamber, it picks up even more heat from the intake manifold. So not only with the intercooler cool the air, but as my homie SiN-6 mentioned cooler air is denser air is safer air.

Hrmm..*cough cough*
whos homie? :p

oh well, i need a new FMIC, or maybe if the leaking can be fix, FUCKING LITTLE ROCKS from a construction site!! ARC man..oh lord..

btw..also get a AFC if u getting a larger intercooler and higher boost, running lean=detonation...good luck

Your my homie because you know what you're talking about ... except that one time, I forget what it was!

Anyways, run water through your FMIC and find the leaks and either seal those parts off or repair it. Good luck!

1bar of boost equals ~14.5psi.

so 1.4bar is ~20.3psi. I boost 13psi on my civic daily which is 0.89bar and 17psi at the track which is ~1.17bar.

On a stock SVO, I think the change was like 300 degrees down to 175 with the intercooler.

But this is an IC that is mounted over the exhaust manifold. You could probably lower the temp even more with a front-mounted IC, or if you do an air-water setup. (IC is sealed in a housing surrounded by water which is cycled through an external reservior.)
