      Features, Description, Reviews, Q&A, Specs & Installation


      • Whipple 10-Rib Supercharger Pulley
      • 6061-T6 Billet Aluminum Construction
      • Black Anodized Finish
      • Engraved Running Diameter

      Adjust Boost = More Power. A Whipple Supercharger 10-Rib Pulley will add additional boost to your Whipple Supercharged 2007-2014 Shelby GT500 for even more tire shredding power. You can order the Whipple Supercharger Pulley in your choice of sizes, spanning from 2.75" up to 4.00" for your 2.9L, 3.4L or 4.0L Whipple Supercharged Shelby.

      Superior Materials. CNC-machined from billet aluminum, the 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 2007-2014 Shelby GT500 Mustangs equipped with a 2.9L, 3.4L or 4.0L Whipple Supercharger ONLY. Please choose your pulley size from the options above.

      Please Note. A change of 0.125" in pulley diameter yields about 1 PSI change.

        Great power gain

        This pulley is easy to install and power gain is absolutely noticeable right away, its instant power it spins wheels without any problems. Tested on a 60mph roll and its way faster than before.

        The increase in performance was phenomenal with just a pulley change. It seems to good to be true. I will bring to tuner to insure it was put on right.

        Whipple Black 10-Rib Pulley (07-14 GT500)

        I had a 3.00 pulley on my 2009 GT500 with a 2.9L Whipple and changed to this pulley. It added 4 psi boost using the same belt with no belt slip.

      I have a 2008 GT500 with a 2.9 Whipple Supercharger with a 3.00 pulley. If I go from 3.00 to 2.75 will that cause belt slip?

      My 08 GT-500 has a few bolt on's, my goal is to make 650-675 hp. on 91 octane pump gas. Im running a Ford Racing shorty headers with Borla cat back, ford racing 113mm cold air intake, Ford Racing 65mm throttle body,VMP fuel pump booster .and 3:73 gears. I have a gen 2 Whipple supercharger that im about to install but I'm missing the main drive pulley. I was wondering if you can help me select the proper size pulley that I'll need to meet my goal. I'm also thinking up grading the fuel injector size too, and not sure which to buy.

      • We recommend contacting your tuner to get their recommendation on pulley and injectors size.
