Key Product Specs
  • If you've installed the Phase 1 Supercharger Kit from Roush and want to expand your power even further, Roush's Supercharger Single Belt Phase 1-2 Upgrade is just what your 2005-2009 Mustang GT needs. It boasts power gains of 75 HP and 115 lb/ft of torque over the phase 1 kit, providing for a total 550 horsepower and 550 lb/ft of torque.

  • Roush has specifically designed these superchargers to be easily upgraded by reusing a lot of the parts that you have installed from the phase 1 kit. The upgrade kit comes with an 80mm supercharger pulley, a GT500 fuel system upgrade and the flash voucher card to have your PCM tuned. This must be done using the Roush Diagnostic Tool and pass-thru device. If you dont have access to one, you can send your PCM to Roush and they will tune it for you!
