Running a KB supercharger @10psi, thinking of getting a lightened flywheel but I've heard from a few people that you need the rotating weight to help build boost. Can anyone explain why this is true or if it is even true at all?
I have a '96 with a KB and 10psi. I also have a lightened flywheel and never have a problem building boost. Full 10 psi by 3000 rpm and it does not drop off even with my little 1.5l.
