Stage 3 adds an intercooler, but does not increase the HP. It makes the engine run 20 degrees cooler... You guys think it's worth adding? 3K to add it. I've already ordered all the parts for stage 2, but I can get the intercooler here pretty quick...

Opinions please.

i say say yes, anybody that i know that has ever run a turbo makes sure they run an intercooler

Is one of the MOST important mods for a FI car.

At wide open throttle and full boost the hot compressed air coming from a turbocharger is probably between 250 and 350 deg F depending on the particular turbo, boost pressure, outside air temperature, etc.. We want to cool it down, which reduces its volume so we can pack more air molecules into the cylinders and reduce the engine's likelihood of detonation

Yes, the intercooler helps sustain the power band longer. Did you add the long tube headers or the shorties?

Please email me privately with your contact info. I would like to speak with you about this. The guy who sold me this, I don't think knows much about it.

Ok.

This thread is funny.

I agree maybe he has the signatures turned off???
