Well, my supercharger pulley cracked in the accident, so I just figured i'd upgrade. My question is, if I were to run the 3.1 or 3.0 pulley, what belt size would I need? I have one a little smaller than stock, and am not sure what to do.
Your fine down to the 3.0" with the stock (GM SC kit) belt. The tensioner will make up for the difference. If you wanted to go the extra step though you could buy the 2.0 SC stage two belt and cut a rib out, but if your going to the 3" don't bother (assuming your tensioner is in good order).
