2010-2012 Mustang Shelby GT500 650 HP Performance Upgrade Parts

Don't be beat by the new 2013 and 2014 Shelby GT500! Add more power to your 2010, 2011 or 2012 Shelby GT500 with JDM Engineering's Shelby GT500 650 HP Power Upgrade Package!

This package includes the same components as the 600 HP kit but adds a 2.60” supercharger pulley along with a Dual Bearing Auxiliary Idler Kit to maximize belt wrap & eliminate slippage. The addition of the smaller blower pulley spins the stock supercharger fast enough to increase boost nearly 4 psi which results in a gain of 50 horsepower and approximately 60 more pound feet of torque!!
This kit can be installed in about 4 hours and requires a pulley removal/install tool which can be purchased or rented through Team JDM HERE.
