This listing is for an uprated supercharger pulley for the vehicle listed in the title. Our pulley gives the supercharger a driven speed increase of 7.5%, the maximum amount possible without modifying the supercharger snout. This pulley is made from high grade stainless steel, CNC machined and produced to the highest standards of surface finish and dimensional tolerances of any pulley on the market. The 7.5% increased supercharger speed and therefore boost equating to about 1.5psi increase, giving typically around 25bhp across the mid range and top end. Changing the pulley ratio increases supercharger rpm and produces more boost. The direct increase in airflow is seen by the ECU where it will compensate fueling accordingly thus increasing power across the rpm with impressive mid-range. Wh.
