STARTLINE PERFORMANCE B7 B8 B8.5 S4, S5, Q5, SQ5; C7.5 A6, A7, Q7 3.0T Supercharger Crank Pulley – BOLT ON STYLE

Startline Performance Crank Pulley Upgrades dramatically increase horsepower and torque by increasing the rotational speed of the factory supercharger. Startline Performance Pulley increased supercharger speeds, and in turn allows the engine to create more power. Crank Pulley Upgrade increases the diameter of the factory pulley from 162mm to 189mm. This results in a larger bump in horsepower and torque across the entire RPM range, as the supercharger is spinning at an even higher rate of speed. It is CNC machined from light weight billet aluminum.
