Shelby GT500 2007-2012 675 HP Performance Upgrade Parts
Free up some safe and reliable horsepower with our JDM 675 Horsepower upgrade kit. This JDM 675 kit optimizes the factory supercharged setup, eliminating the need to upgrade to potentially $5000.00+ superchargers to reach the same power levels. The components of this kit are the same as the JDM 650 Horsepower kit, with the addition of a Ford Racing throttle body. The stock Ford air kit is replaced by the JLT 123mm in order to increase air flow and extend the range of the mass air flow sensor.
With all parts combined your GT500 will net over 675 HP at the engine and gain approximately 125 horsepower to the wheels from stock! This sort of improvement will make you think about getting a better set of tires!
Expect a noticeable bump in throttle response with improved tip in feel. Bus loads of off idle torque are available from idle all the way to redline with our tune, so be prepared to shred some tires on demand. Expect with traction to easily shed tenths off of your 1/4 mile ET. A slight bump in fuel economy is to be expected ranging from 1-3 MPG average.
You also can safely add efficiency and power as well from cooler air charge temps with an AFCO heat exchanger listed here, and a Ford Performance upgraded intercooler listed here.
The kit can be installed in 5-6 hours and requires a pulley removal/install tool for the supercharger.
Pulley tool sold separate. See details on the VMP Pulley Removal Tool Here
