The 928 Motorsports Bearings: We are the original developer of the high-speed bearing for the Powerdyne Supercharger. Working with engineers at SKF, we were able to come up with the right hi-temp grease, the right bearings, and the right alloy inner and outer races to get up to 50,000 rpm out of these bearings where they had been previously limited to 36,000 rpm. Since then: We have improved upon the 2002 formulation, and been able to have an even better bearing manufactured just for us. 928 Motorsports LLC is the only supplier of these high speed bearings for the Powerdyne supercharger in the World. The lubricant inside these bearings will tolerate up to 550 degrees F without failure - over 250 degrees more than the standard bearings.
The 928 Motorsports Belt: We improved on the original belt, too. Raising the impeller speed to 50,000 rpm from 36,000 rpm (stock) requires a tougher belt. Kevlar is a step in the right direction, but its not enough. You also need stronger roots on the cogged teeth or the backlash when shifting will rip the teeth off the belt! The 928 Motorsports 33 G1 belt is the product of that collaborative effort between us and Gates Engineering. Same Kevlar backing as it's GT cousin, but with better rubbers, stronger teeth and cast from a special mold just for us.
Pulley Sizing: With these changes, you can go up a pulley size without loosing performance. Using a larger pulley on your supercharger will eliminate belt slippage and also make the bearings last longer. Or - you can keep the pulley size you have and enjoy up to 20% more boost than you had before!
