Thread: Supercharger Pulley Question

What is the point of changing the size of the pulley?
If you do change it do you have to do any PCM Tuning?
Is it really worth it?

A smaller pulley makes the rotors spin faster, thus more boost. On the downside, it also means more heat.

It is only worth it if you can run a smaller pulley safely. Do some more research and read the safely modding your 3800 thread. You need flow mods and a tune, (intake and headers) before you should start thinking about dropping pulley sizes. You don't wanna chip a piston.
