the thing i didn't mention was that they also said to bypass a lot of coolant that flows through the intake manifold and devices thereon, THAT is where the temperature drop is, not from gaskets. the reason throttle body get's heat is to warm up the air going in (what YOU in particular are trying to avoid) which keeps the car running richer, it's purpose is for emissions reasons, since you're supercharging i'm pretty sure you don't care at all about that, basically i'm agreeing with yes you will have lower intake air temps by bypassing some coolant flow through the intake manifold BUT, the gaskets shouldn't receive any glamour for the result of lower temp because of the bypasses.
