How big of a intercooler should I run. Goals is 500whp running E85. Full race manifold, borg warner S258, and I was thinking going 3" piping, but I have read and been told that it might be too big and will cause. So 2.5" is what I am looking at using now. Also has anyone measured the room behind the bumper. Whats the largest that can fit back there without cutting the front bumper support. Thanks.

 

2.5" is fine for 500whp

 

Largest I have seen is from FullRace or AFI, both are very nice units rather than the off the shelf Precisions most others use (Though they do have a VERY nice core).

 

get a used precision 600, cheap, realiable, great quality.

 

Yes but they do not fit between the rails, the core is about 6-8" too long and could be a bit taller also.

135.00 for the 600hp intercooler. Fits under the bumper rails too. Can't beat that price from a reputable dealer.

 

Nice thankf for the link. Thats cheaper than the Godspeed intercooler.

 

The precision600 fits without any modifications to your car or bumper/grill area. Hell I'm running the precision750. stock grill and unmodified oem bumper with no issues.

 

Ill just go with that one that the other person linked. Precision is going to be a lot more money. Thanks.

 

If your shopping turbo parts based on price.. buy another car.
