Hey guys need your expert advice. I have a built z06 with a Vortech supercharger boosting about 14lbs of boost. Car pushed 700hp to the rear wheels. Started having problems with the belt coming off the supercharger. When I first got my car back i had no issues. The only thing I did was change the alternater. They machined the aftermarket alternater so the pulley would align. But this is the third time I'm going to do the serpentine belt. I currently have an upgraded 6rib pulley set. Do you guys recommend a flip drive? And if yes who makes the best flip drive and what em I looking at price wise and price for someone to install? Do I have to retune?
