buying an Intercooler

Raptor · 12-10-2004

It will definately have a larger effect on higher boost levels, how much is hard to figure exactly. Some vary carefull testing will need to be done to get accurate info. The truely telling tests will have to wait till spring at the trac since that is where the performance gains are desired and under those conditions. I am bugging the engineering groups into telling me their opinions on the effect in our situation considering the speed of the charge etc as well. By the time this is done, we should all be a little smarter.

Since it is already a percent, I don't think it is going to drasticly rise with more boost. It might go up or down some, but I don't think it is going to double or triple. I don't see big HP changes on the dyno when my intake air temps are 10 degrees higher, not anything like a 3%(20whp) change at 3 bar absolute if the temp is 10 degrees different. I would like to try some drastic cooling of the intercooler with nitrous or CO2, but it would be hard to get 100% factual results with the CO2 or nitrous contaminating the surround intake air. I guess, if you can get a big HP gain with CO2 then you know it's working, since sucking in CO2 should kill HP. Jason Siebels, the guy who designed the Pro-EFI and AEM EMS standalone doesn't even run an air intake temp sensor on his turbo MKIV Supra. He thinks it is not nearly as important on a turbo car compared to an NA car. I don't know why.
