More Horsepower and Torque! Has the speed bug bit you? Are you itching to increase the power and performance of your Phase 1 Roushcharged GT? Then scratch that itch by installing a Roush Phase 2 Supercharger Upgrade Kit. The Phase 1 Roushcharger already produces an amazing 475 HP and 435 ft-lb of Torque at the flywheel, but after upgrading to a Phase 2 Kit you will see that number jump to an incredible 550 HP and 500 ft-lb of Torque at the flywheel. With an increase of 75 HP and 65 TQ that speed bug will transform your Mustang into a speed demon.

Kit Includes. The Roush R2300 Phase 1 to Phase 2 Supercharger Upgrade Kit includes a new 80mm Bolt-on Pulley, Serpentine Belt, Dual Fuel Pump Kit, ROUSH PCM Flash Voucher Card and installation instructions.

Upgraded ROUSH PCM calibration. ROUSH® PCM calibration is a success of engineering that maximizes the power of the system. ROUSHcharger owners will receive a ROUSH® PCM Flash Voucher Card, which is used to obtain the specific calibration needed for your Mustang and requires ROUSH Diagnostic Tool (RDT) software and a J2534 Pass-Through device to upgrade your PCM (software and pass-through device not included).

Application. This ROUSH Phase 1 to 2 Supercharger Upgrade Kit fits 2010 manual GT Mustangs equipped with the 4.6L Modular V8 engine and a ROUSH Phase 1 TVS Supercharger installed.
