Here is a great package for those looking for the 'extra' performance using the tried and true upgrades. The supercharger pulley upgrade uses a 15% smaller diameter supercharger pulley to increase the boost up to about 15 psi from a stock 10.5 psi. This results in about a 20 hp increase. The crankshaft pulley is a lightweight version that greatly reduces intertial mass and improves the throttle response.
