This Mustang GT Supercharger is a Single Belt Phase 2 kit that brings your 2005-2009 Mustang GT power to a total of 550 hp and 500 lb-ft at the flywheel! 

This Mustang GT Supercharger Kit is part of a line of superchargers kits for Mustang GT's that allow for upgraded performance over time. This "phased" line-up includes two different FEAD systems, which cannot be converted from one to the other. The single belt FEAD systems are less expensive than the comparable dual belt Mustang supercharger kits. However, the dual belt systems provide a more robust control of power, which is especially beneficial for higher horsepower applications.

  • TVS2300 supercharger
  • Induction system
  • 80mm bolt-on pulley
  • Fuel charging assembly
