 Replace the original 3.00" supercharger pulley with a Metco 2.80" overdrive pulley to add 2-3 lbs of boost to your Shelby Mustang or a 2.6" overdrive pulley to add 4-5 lbs of boost. The kit includes a pulley hub machined from high-grade steel that presses onto the blower shaft. The CNC-machined aluminum ring bolts to the steel hub using the supplied stainless steel fasteners, and this two-piece design makes subsequent pulley ring changes a snap. Fits 2007, 2008, 2009, 2010, 2011 Mustang GT500 |
