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.
