    Adjust Boost = More Power. A Whipple Supercharger 8-Rib Pulley will add additional boost to your Whipple Supercharged SVT Cobra for even more tire shredding power. You can order the Whipple SC Pulley in your choice of sizes, spanning from 2.75" up to 4.00". A change of 0.125" in pulley diameter yields about 1 PSI change.

    Superior Materials. CNC-machined from billet aluminum, this Whipple SC Pulley is hard-coat anodized in black for impressive good looks and to resist surface wear. There are no special tools required for this installation - they use the same allen head bolts that are utilized with the original pulley.

    Recommended Upgrade. To realize the full power potential that the Supercharger Pulley has to offer, AmericanMuscle recommends a Bama custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

    Application. The Black Whipple Supercharger Pulley is specifically designed for use on the 2003-2004 SVT Cobra Mustangs equipped with a Whipple Supercharger. Please choose your pulley size from the options above.

    Technical Note. On the 3.75", 3.875" and 4.00" pulley options, they will not fit under your stock hood without K-Member spacers.
