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 engine with incredible potential. This engine utilizes Variable Valve Timing and aggressive spark calibration (with spark knock sensors), which allows the 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!). 

Note: HO and Stage II Tuner Kits (with Factory Airbox) use a 6 rib shared belt drive. 

Tuner Kits: These kits make sense for someone wanting to perform custom tuning of the car and push the envelope in performance.  Will most likely be experimenting with alternative fuels such as 93 octane, race fuel, E85 fuel, and methanol supplemental fuel.  In addition, possibly changing engine components like heads, headers, exhaust, and cams for the engine.
