The bearings in the Powerdyne supercharger receive no oil from the motor to help cool them down, so to make your bearings last - they must be cooled some other way. This kit will cool your bearings with a constant wash of cold air running over them to carry the heat away, increasing the adiabatic efficiency of the blower and bearing life at the same time!

• Cools the bearings in your Powerdyne to extend their life.
• Ball-Bearing radial fan delivers 42 CFM of cool air.
• Draws only 2 amps and is water-resistant. Durable.
