Heat exchanger picture
I know it gets blocked some by the bowtie, but there is a gap between the grill and midpart of the exchanger to flow air. I like where it is because of the clean air it gets as oppesed to really close to the ground. The fins stay nice and clean too. No coolant temp increases with it in front of the condensor either, but that is probably due to the really big radiator 
The heat exchanger is all aluminum made by Ron Davis Racing here in Phoenix (Glendale) They make the radiators for the Pratt and Miller C5R Corvettes. The exchanger I had them make measures 22"x8x2.75" including tanks sizes and has an actual cooling surface area measuring 20"x6.5"x2" (260in^3) It is two cores of one inch tubing. Spearco Intercoolers says to run at least a heat exchanger with a cooling s.a. of 260cubic inches.
Before this exchanger I had a heat exchanger from a '93 gmc Typhoon as my previous cooler, about 120in^3 of s.a. cooling, and it seemed to do okay. But after a hard run I could open the pressure cap to the system and the water would want to run out the overflow. (this is in about 80* ambient heat) It was still warm, but not by any means hot. So there was room for improvement
I think the the main determinant for hp system handling is solved from the size of the intercooler itself. Speraco states the 2-230 intercooler will flow 1500cfm and about 1100hp. I imagine that if you meet the minimum criteria of a 260in^3 of cooling suface area you can stay in a relatively efficient area of operation as far as the intake air cooling system goes. I would say this setup would rock all the way up to 750rwhp if not a little more before a larger interooler and heat exchanger would need to be considered to make cooling more efficient.

Nice!, I thought I saw something shiny behind the grill in your pic thread.
You have any dyno numbers on that sucker yet.....at more than 3psi?
When does the 3.3L go on?

I can't wait to see some better numbers running some real boost.
