I'm no expert on forced induction, but I agree with Tim Z if it works good for a stock setup making 32lbs why won't it work with a smaller engine with half the pressure?? In theory it makes sense right? Is there anyone that's done or seen it done with good or bad results? It's definitely a good thought for sure.

The Duramax coolers don't fit without a lot of hacking and modding. The CX Racing fit and to a great job for the 6-700hp and below crowd which is the majority of my customers. You really can't uses Foose04's comparison as a great example as his EST intercooler was also an 1" thicker then the CX Racing intercooler he was running. That's a lot of extra flow and surface area to dissipate heat. He is also running 70/72/now a 76mm turbo's in the 18-20psi range. How many guys on here are doing that???
I also use the ETS intercooler on my BIG HP builds but they cost a lot more.

You may want to take a look on ls1tech. There are a lot of guys running ebay I/C with great success. I went the times in my sig with one. Cablebandit went 9.29 @ 153 in a 3800 lb car with one also. Are they the best I/C made? No, but for the money they work great. I would not use one for an all out race car, but for a DD and fun at the track they can't be beat.

I notice this was for a Whipple. Seems I read somewhere (can't remember where) that A2A I/C's don't work well with PD systems. Apparently, since the rotors are sync-locked to the crank, they have trouble filling up the additional volume without losing boost. Hence, most PD systems use A2W coolers. Turbo's OTOH will just spin more until the boost pressure is reached and the load on the pump side equals the power on the turbine side. Can anyone confirm or refute this?
