We take a 2011 Shelby GT500 Ford Mustang in bone stock form and add some bolt-on modifications that will increase both horsepower and torque. We added a cold air intake, upper supercharger pulley, lower harmonic balancer, off-road x-pipe, high-capacity heat exchanger, colder plugs and topped it off with a Bama Performance custom tune for huge increases in power - almost 600HP at the tires! Make sure you watch the video for dyno results and to see this GT500 go from mild to wild! This video will work on any 2010, 2011 and 2012 Shelby GT500 Mustang! less
