Smaller supercharge pulley

I'm not sure about the size you're mentioning. Sites like ZZ Performance have info on what sizes work with your mods. Too small a pulley will cause the supercharger to over heat the intake air charge which will cause harmful detonation among other things. There are other mods you can do to control the temps and to make sure you have enough fuel to go with all that compressed air you are generating. All that info is on the ZZP site and others like it. Do your homework first.
