Powerdyne® BD-600, BD-10, BD-11, or BD-11a Supercharger Venting and Shimming


Less heat, More Power, and Longer Service Life for only $139.00

To get more CFM and boost from your Powerdyne, most users will go to a smaller pulley. That works, but it is not the ONLY way to get more performance form your Powerdyne.

If you use bearings with tighter tolerances (like we do), an experienced technician can carefully shim out the impeller so it is closer to the casing. This reduces blow-by - and more of what air the impeller moves gets pushed out to your motor - just like we want.

Next - we need to carry away more of the heat from the bearings in the Powerdyne case. They receive no oil from the motor, and can only cool themselves by dissipating heat into the aluminum casing. If they overheat, the lubricating oil breaks down, and the picture below shows the result.

In our Venting process, we mill and drill your supercharger cover to accept 2 high-quality stainless steel vents - positioned exactly where the internal belt can act like a fan and circulate the air thru the supercharger. Each vent filters the air to 100 microns (to prevent dust and dirt from entering) yet allows more than 60 CFM of cool air to pass over your bearings.

The vents are highly-corrosion resistant, will never tarnish or yellow, and are designed to handle more than 300 degrees Fahrenheit!

Venting your Powerdyne is the best way to get longer service between rebuilds - a 928 Motorsports exclusive!
