BIGGER IS BETTER 

Our Stage II system includes a fuel system upgrade and our higher performance intercooler, over 75% larger than our HO intercooler, ensuring your air charge will be at its lowest temperature before entering the throttle body.  Our engineers have designed this system for a capable DIY’er making it easy to install while still delivering monster power numbers requiring no fabrication at all! 

It’s still hard to believe that our Mustang supercharger systems can deliver more Hp increase than the total HP a stock Mustang GT left the factory with a decade ago. Now that is progress!

 The Coyote 5.0L is an incredible motor with incredible potential.  This engine utilizes Variable Valve Timing and aggressive spark calibration (with spark knock sensors), which allows this engine to constantly push itself to its potential.  Factory Hp is a rock solid 460Hp at the crank, and we build on that firm foundation with performance upgrades that go beyond a Horsepower increase of 70%+ (approaching 800 total Crank HP!). Our approach is to offer 4 power upgrade options depending on how far you want to push your new Mustang.
