I have a vortech blower and am only running 7psi (the stock pulley) but id like to be in the 15lb range (yes I have a built motor) Whats the mast boost I can run on a 6-rib belt before I start getting belt slip, and what all does it take to convert to 8-Rib? is it even worth it? Harmonic Balancer, A/C pulley, P/S pulley, Belt tensioners, Blower, Water Pump... What will all this run or should I just still with a 6-rib?
