Just a question: does this 10 degree drop in temperature mean from the intake to TB or TB to engine. My worry and thought is that it would take a drastic drop in air intake temperature to even see a 2-3 hp gain as the heat of the TB etc. is so hot that it's sort of working like a hair dryer: cool air enters from the back but because the internal components are so hot, it blows out hot air on the front end instantly - air can be heated up so quickly that cooling down intake temperature even 10 degrees seems like it wouldn't help much, intercoolers on turbos work well because they drastically cool down the air... correct?
