The WayMotorWorks custom 19% MINI Cooper Supercharger pulley for R53 MINI Cooper S increases the rotating speed of the supercharger by reducing the diameter of the pulley driving your supercharger. Our design has the following features not found on other pulleys: A 2 piece collet style design utilizing 4 bolts to lock the pulley to the supercharger shaft. Taller lips on the front and back to ensure the belt stays put while driving and for easier belt installation. Four jack bolt holes to allow for reduced weight and to ensure proper installation.
The WMW pulley is CNC machined from the highest quality stainless steel to exacting tolerances for perfect balance. The 19% size reduction pulley is not recommended for track or high rpm use. For the R53 Mini Cooper S the pulley swap is definitely the best HP for your buck modification!
