Whipple Superchargers 3.50" Pulley
If you are in need of more boost for your Whipple Supercharged 2011-2019 Mustang GT, upgrade to a smaller pulley! The best part of it all, no special tools are required for a pulley change. They are secured with the same four allen head bolts used to mount the original pulley. Each Whipple Supercharger pulley is made of 6061-T6 billet aluminum and anodized in black for wear and environmental protection. These pulleys are engraved with the running diameter size and state-of-the-art lightweight pockets to lower reciprocating mass as well as a guard feature to help unwanted belt wandering during hard running. Each 1/8" of pulley diameter is about 1 psi in boost change.
