The Pulley provided in this kit will be a 3.25".
Pulley Size included on Supercharger 2007-2014 Shelby GT500 Whipple Supercharger Kit - Gen 5 Crusher 3.0L for Mustang GT500 (WK-2505B)
Description says the pulley is a 3.5 in one paragraph, but says 3.25 included in kit. So which one is on the supercharger out of the box? Does the Custom Tune in this kit support the 3.5 or 3.25 pulley?
