Are Vortech's pulleys interchangeable with the Procharger's? Is the key the same size? I am thinking about switching pulleys but the one I found is a procharger pulley. The seller said they are the same. Does anyone know for sure?

 

Isn't the procharger pulley an 8 rib. Vortech is 6 rib.

 

I think each brand makes 6, 8, 10, and 12 rib pulley combos.

 

I don't know the specs on the shaft size of Vortech's pulleys, but the shaft size of a ProCharger pulley for the P1SC, D1SC, D1, etc is 0.971 and the key width is 0.188. For the P600B, the shaft size is 0.733 and the key width is 0.125.

I just found that the shaft diameter for a V2 is approx. 0.786 if that helps at all.

 

ProCharger doesn't do 10 rib.
