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 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 clear anodized. Dimension of each supercharger pulley is based off of the running diameter.

1025/1075/1200SCI: Stock diameter is 4.05".

850SCI: Stock Diameter 4.73" (use 4.65" for replacement).

*A general rule of thumb is every .125" of pulley change is .75psi of boost (increase/decrease). There are no returns or exchanges for used pulleys. PCM's will control boost levels in stock form, therefore boost levels will not change with pulley changes.

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