      More Horsepower and Torque! Increase the power and performance of your current 670 HP Roush R2300 Phase 1 Supercharger to an impressive 727 horsepower and 610 lb-ft of torque with a Phase 2 Supercharger Upgrade Kit.

      Kit Includes. The Roush Phase 1 to Phase 2 Supercharger Upgrade Kit includes a new 80mm S/C Pulley, a preset plug and play digital fuel pump controller, cooler range NGK spark plugs, ROUSH PCM Flash Voucher Card and installation instructions.

      Roush Performance Quality - Guaranteed. Roush is known for a rich tradition of excellent racing performance engineering at the highest level of OEM quality and design. This Supercharger upgrade kit features a 3 Year/36,000 Mile Parts limited warranty (ROUSH Supplied Parts Only).

      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). If you don't have access to a pass-through device, you have the option of sending your PCM back to Roush, where they will flash your PCM for an additional $100 fee.

      Application. This ROUSH Phase 2 Supercharger Upgrade Kit works with both manual and automatic 2015-2017 GT Mustangs equipped with the Coyote 5.0L DOHC 4 valve V8 engine and a ROUSH R2300 Phase 1 TVS Supercharger that produces 670 horsepower. This voids optional Roush limited powertrain/drivetrain warranties.
