per Frank S
do away with the 8speed belt drive with the 1 1/2 HP motor for a 5 HP 3 ph motor that I have and a 3ph VFD I figure by going to 5HP even at the slower speeds it should still have sufficient torque if not then I will incorporate a 3 or 4 sp transmission

A good plan. Lots of potential in a transmission, beyond what power alone can do.

Well I really don't like multi groove pullies as a means of speed increase or reduction more especially when more than 2 multi groove pullies are required
