      • Whipple 8-Rib Supercharger Pulley
      • 6061-T6 Billet Aluminum Construction

      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.

        More Boost :)

        Well worth the money! It took about 8-10 minutes to remove belt/pulley and install a new Gates green belt and Whipple pulley. I gained 3-4 psi of boost with a 3.00 over the stock 3.50. The Pulley is lightweight and clean looking. The only bad part of the pulley is being black anodized, after some long us (track, hard pulls) the pulley will turn dark purple but it still those it's job

      What is the boost output for each pulley?

      • The overall boost achieved with each sizing of Whipple Supercharger 8-Rib Pulley will depend on a number of factors, including which Whipple supercharger you have, and additional modifications you have done to the car. A general rule of thumb is that each .125" of pulley change will net approximately 1psi of boost.

      I'm trying to find out if the 3.4 Whipple supercharger pulley #102490-K will work on my 2002 Ford Lightning with a new Whipple 3.4 charger? I would like to order the pulley but need to know for sure if it will work on the Ford Lightning.

      • Unfortunately we can only guarantee fitment for Ford Mustangs, I would recommend checking directly with Whipple for the answer to that question.
