WHIPPLE SUPERCHARGER PULLEY - 6 RIB - 5 BOLT - 3" DIAMETER - SCP-63000-5

Every Whipple Supercharger pulley is made of 6061-T6 billet aluminum and anodized for wear and environmental protection. Each pulley is 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. Standard finish is hard coated black anodized. Dimension of each supercharger pulley is based off of the running diameter.

*A general rule of thumb is every .125" of pulley change is 1 psi of boost. There are no returns or exchanges for used pulleys.

**Whipple Supercharger pulleys are specific to the application. Do not order this pulley for a different application.

About Whipple Supercharger

Whipple Superchargers is owned and operated by it’s founder Art Whipple and is located in Fresno, CA. Founder and president Art Whipple has always been regarded as a true innovator and enjoyed a very successful racing career as crew chief and owner of Top Fuel Funny Cars and Dragsters, as well as many other forms of racing such as circle and drag boats.While owning and tuning the famed Revelloution Top Fuel Funny Car, Art and driver Ed "The Ace" McCulloch won the 1970 NHRA US Nationals and NHRA 1971 Winter Nationals. Art later retired from racing to start a family but quickly found himself again tuning for his father in-law, Ed Wills which fielded Top Fuel Funny Cars and Top Fuel Hydro boats under the famed "Mr. Ed" and "Whipple & Mr. Ed" banners.

In 1987, Art Whipple got the performance bug again and decided to get back into the performance industry with some new technology. After countless hours of research, Art found a company located in Australia named Sprintex. Whipple quickly adapted their unique "twin-screw" supercharger to his own personal 1988 Chevrolet Silverado. Within a few months, Whipple Superchargers became the exclusive distributor of the Sprintex Supercharger.
