2007-2009 Shelby GT500 Replacement Superchargers

Sort by:

JMS is the industry-leader in upgrading 2007-2009 Shelby GT500 Mustang superchargers, and we build some of the most powerful modified versions of these cars in the world.  Over the years we've learned a lot about how to maximize the power hidden inside the factory blower.  We've also learned a lot about taking GT500 builds to the next level, and stratospheric levels of horsepower and torque.


The stock 2007-2009 Shelby GT500 is already a brute with over 500 HP, and capable of much more with just some basic twisting of the screw.  However, if you want to go big, you're probably a candidate for something with a little more boost and higher design parameters than the OEM supercharger will support.  JMS carries a full line of aftermarket supercharger systems and replacement head units, and has the most experience tuning and building 1,000+ RWHP Mustangs.
