You need the diameters of: (where the belt rides) The drive pulley (crank). The driven pulley (pulley on the supercharger) Plus the internal supercharger ratio. Max engine rpm.

Internal SC ratio is V3 setup so thats pretty easy since they have that option. Drive pulley (Crank) - Okay I will put 5.5" since that is what I replaced my previous crank pulley with. An ATI 5.5" Street Super Dampnr pulley. Max engine RPM: 7800 to be general. Diameter of where the belt rides like how big the belt is in diameter?

This set-up uses 2 belts, right? (sorry, I was thinking of one belt) So you need the crank pulley and the driven jackshaft pulley. Then the jackshaft drive pulley and the driven supercharger pulley.
