The MOTOBLUE™ Interchangeable “QC” Blower Pulley System for the factory supercharger. The factory blower pulley is pressed onto the shaft - which makes quick, trackside changes impossible. With the MOTOBLUE™ Interchangeable “QC” Blower Pulley Kit you simply replace the factory blower pulley with a precisely machined steel hub and attach your choice of pulleys with the 5 grade o allen head set screws provided.

Running a larger pulley on the street saves fuel, while the 2..65" bumps the boost for an impressive 100+ horsepower gain (tuner required). Best of all you don’t pay the high price other manufactures are trying to charge for the same technology.
