First start after 928 Motorsports rebuilt my BD11A supercharger. Much quieter and I had them install a Competition belt, upgraded impeller shaft, pulley shaft, case venting, better bearings and a smaller pulley. More boost is happening.... She is pulling nicely. Evolene38
I just received my rebuilt supercharger for my Escalade from you guys and it is working great! Thank you so much for the quick and friendly service! John N
Our techs will open your Powerdyne up, inspect it, clean it, replace all 4 bearings and the belt, re-assemble it, bench-test it, and return it to you. Our turn-around is fast, most of our customers receive their supercharger within 1 week from the time we receive it.
We use ABEC-7 dust-sealed HSS deep-grove bearings (Powerdyne uses an ABEC-5 rated bearing). Our bearings are rated at 7 tons - beyond the work load and more durable than the older OEM Powerdyne bearings. Because our bearings have tighter tolerances, they whine a little bit more than the OEM bearings, but most owners report an increase in blower boost output.
MULTIPLE BENEFITS: Use this rebuild and your stock pulley to lengthen your service intervals, or go down a pulley size to pick up some more HP. It's up to you!
PURCHASING: Add the item below to your cart and check out to pay for the racing rebuild service. Then just pack and ship your head unit to: 928 Motorsports LLC, 604 E Maple St, Horicon, WI 53032 We recommend you pack it well and insure the shipment.
WHAT TO SHIP: Ship only the supercharger to us for rebuilding. The drive pulley can stay on. There will be a surcharge if there are any mounting brackets, idler pulleys, etc that we must remove in order to rebuild the unit.
Superchargers that arrive without payment or contact information do not get worked on.
