Bundle the famous 64mm supercharger pulley and tune for an easy bolt on power package.

UPD 64mm m112k supercharger pulley is made of lightweight billet aluminum for reduced rotating mass and quicker clutch engagement. Lightweight means less belt slip as well. UPD 64mm pulley is only 1.5lbs verses well over 2 lbs for the stock 74mm steel pulley. Much easier and safer on engine parts to install verses adding a much heavier aftermarket crank pulley. Adding a smaller supercharger pulley will not turn your accessories faster verses adding an oversize crank pulley will greatly increase rpm on all your idlers, AC, power steering components and leading to early failure.
