This is a replacement pulley for our Modular Pulley System that removes the stock supercharger pulley and replaces it with our stainless hub, and these pulleys will bolt onto that hub. A jaw style puller should never be used to remove a supercharger pulley - if it is used, it will destroy the pulley and possibly damage the supercharger. We recommend using our Supercharger Pulley Puller. Once installed the hub allows quick changing of pulleys with an Allen wrench. The ZZP MPS allows you to change between pulleys depending on conditions, use one pulley for street use and a smaller for the track or when running high octane fuel. A modular pulley system is a must for those planning to continue to modify their car in the future.

3.2 pulley

My L67 conversion was using a 3.4 pulley. It made 284hp to the tires on this size pulley that is 7-7.5psi of boost. Swapping to this pulley will have put me over 300whp. I can definitely tell the difference from the 3.4. Also it took me about 5minutes to change. Very satisfied�

Truly Boosted!

Very glad that I went this direction! I now have a eight rib drive belt and a 3.0 inch pulley, which is really what I needed for the L36 conversion to come to life.
