Anybody know a good calc to size a intercooler? Edit: found a good explanation of how to calculate the size, its somewhat generic but should work well if you can get some of the data on the core like the example shows from Spearco. http://www.turbosaturns.net/articles/intercooler_sizing.html Yeah.. WRX people almost always go way too big on IC's. If the top mount wasn't in such a crappy position (on top of a hot engine bay) it would be probably of a all right size. I plan on going front mount.. but I have some things in mind different from the norm. 04 Subaru WRX "Eurosport bling bling fast and furious tokyo drift" "They have diarrhea of the mouth, and constipation of thought"

I understand alot of piping for an intercooler hurts boost. but would a intercooler with way more cfm's than needed hurt power? Or is this a realy stupid question 98 csvt t-red.. sho-shop intake, b&m, fidanza, spec1 clutch, Torsen, DMD,optimized Y& TB, Brullen, rear strut bar,h&r's,17" konig traffik's.

(the fin design being equal of course) Any drop makes the compressor work harder for the same cfm flow after the intercooler respectively. That equates to more heat. The good thing is most quality aftermarket intercoolers are pretty efficient to begin with. 2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.
