    Supercharger Upgrade Kits

    Kit Contains:

  • Fuel pump voltage regulator
  • Plug-n-play Wiring harnesses
  • 80mm supercharger pulley

  • The Roush Phase 3 Supercharger Kit is the best way to add serious power to your 2011-2014 5.0L Ford Mustang GT. It is calibrated to give you 675 HP and 585 FT/LB of torque. That's a huge increase of 255 HP and 195 FT/LB over stock!

    With all of this new horsepower under your hood you are going to need an upgraded fuel delivery system. Roush has you covered with a fuel system upgrade that will ensure your engine gets the fuel it needs to perform. A fuel pump voltage regulator and easy to install wiring harness were developed specifically for this kit. Just plug it in and you are protected against extreme fuel-to-air changes and possible engine damage.

    This 675 HP phase 3 kit is part of the TVS (Twin Vortices Series) line of superchargers, developed by Roush. It raises the bar for performance, reliability and efficiency. For years Roush has had a proven record with this series and it shows with their own Roush built vehicles. You can expect more power, better fuel economy, with a smaller package. Truly uncompromised performance that you can only get from Roush Superchargers.

  • 675 HP and 585 LB/FT of torque (using 93 octane fuel)
  • R2300 supercharger featuring TVS technology
