How helpful is a TB spacer?
Question says all. Is it good at reducing KN? If one has a spacer, could they run a 3.3 pulley instead of a 3.4?

TB spacers have no effect on KR (not KN). They're primarily for providing a point for Nitrous or Water Injection.
The length of the intake is not as important of a factor in a supercharged car as it is in a NA car.
If you think about it, wouldn't lengthening the pipe on your CAI accomplish the same thing?

the only REAL benefit would be if it were to block off coolant passage through the throttle body, or separating it from heat sources theoretically decreasing intake temps by a fraction of a degree, but nothing that i think could make much difference at all certainly NOT a pulley size difference

No, I wasn't thinking that way. I was thinking something along the lines of insulating the TB from the hot supercharger. Aluminum seems to spread heat quite well. It SEEMS to make sense. At least that is what ZZP says.

A throttle body spacer will insulate your TB from the heat of the supercharger. Keeping your TB cool will help keep your intake temperatures down thus reducing KR and increasing HP potential. The inlet is 72mm to work great with our ported throttlebodies.

Not really. Even if your TB was hot (ignoring the fact that the coolant COOLS your TB at high temps) how much heat do you really think that high-velocity air will pick up from the hot aluminum in a few miliseconds?
