This is Sean Kelley’s automatic 2012 Mustang GT being tuned at Dyno Tuned Performance in Virginia. The car put down 713 rear wheel horsepower and 540 rear wheel torque. Sean Kelley owns Kelley Performance (Check them out on Facebook) and has quite the 2012 Mustang GT, being powered by a Paxton 2200 supercharger which is complimented by CNC ported heads, JPC/Metco fuel system, and ARH long tube headers. The car still has the stock cams, stock mufflers, stock automatic transmission along with the stock torque converter. So there is still plenty of ways to unleash more angry from this car.
