[QUOTE="04SolidSnake, post: 9657259, member: 34055"] You aren't right here my friend. I think you are mistaking heat soaking the engine, with heat soaking the blower. Heak soak will definately be an issue. No heat exchanger is 100% efficient. It are those ineffciencies that lead to heat soak. Running balls out in the desert is going to heat soak just as badly as a dyno pull.. Since you heat exchanger is not 100% efficient, it cannot pull all of the heat out of the water flowing through the heat exchanger.. This cycle over and over again will cause IAT2 to climb, and it will rob you of power. Further to this, ambient temperature will also affect not only IAT, but also IAT2s since your heat exchanger is only going to cool the intercooler fluid to ambient at best. The only way heat soak can be taken out of the equation would be to have a heat exchange system which can pull the IC fluid temperatures down to below ambient temperature like the Killer Chiller systems which use the vehicles air conditioning system to super cool the intercooler system coolant. This allows water temperatures to fall below ambient temperature, and thus will prevent heat soaking the blower. [/QUOTE]
