      • Phase 1 Kit - 700 Horsepower / 610 lb-ft of Torque
      • 2.65L TVS® Ford Mustang Supercharger
      • ROUSH Designed Upper and Lower Aluminum Intake Manifolds
      • All Aluminum, High-efficiency Intercooler and Full-face Radiator
      • Three Year/36,000 Mile Limited ROUSH Powertrain Warranty Included
      • CARB EO Number: D-418-33
      • Fits 2018-2020 GT Mustang Models


      More Ponies, For More Fun. The 2018-2020 GT Mustang already arrives from the factory with an impressive 460 Horsepower and 420 lb/ft of Torque in its stock form. However, after installing a Roush R2650 Phase 1 Kit those numbers will jump to an astounding 700 horsepower and 610 lb/ft of Torque, that's 240 more ponies over stock!

      Monstrous Blower Kit, Roush Style. This complete package transforms your 2018-2020 GT into a track-shredding beast. Kit comes complete with a 2.65L TVS® supercharger with black finish, upper and lower intake manifolds, an air-to-water intercooler, full face radiator, high capacity coolant degas bottle, and a high-flow induction system with larger throttle body.

      New High-flow Technology. The ROUSH Phase 1 R2650 supercharger features Eaton's newly designed Twin Vortices Series technology (TVS) rotating assembly that features high-flowing front inlet and outlet ports for additional volume and better efficiency which delivers more power and increased fuel economy. This a roots-type, positive displacement supercharger features twin four-lobe rotors that are twisted 170-degrees to greatly enhance thermal efficiency, enabling higher volume capacity, and higher operational speeds.

      Upgraded ROUSH PCM Calibration Included. 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 do not have access to an approved pass-thru device, you can send your PCM back to ROUSH to be flashed for additional $100.00 fee.

      Three-Year/36,000 Mile ROUSH Powertrain Warranty. Roush Supercharger Kits come with an extended powertrain warranty, which is good for 3 years or 36,000 miles from the date of retail purchase for complete peace of mind. Some exclusions may apply, please see manufacturer's warranty for complete details.

      Application. This Roush R2650 700HP Phase 1 Supercharger Kit is specifically designed for use on the 2018-2020 GT Mustang equipped with the 5.0L 4V coyote engine. Fits both manual and automatic transmissions.

      Please Note. Roush Supercharger Systems are built to order for our customers and because of this, there can be a 2 to 4 week lead time on orders once your information is received.

        2019 PP2

        This is the perfect addition to the PP2 while maintaining warranty. The only drawback is the cooling brick hits it’s limit after a few pulls, hence 4/5 stars. There are other systems that use the “lid style” brick locations that handle heat much better. That being said 650whp is more than the cup2s care to handle anyway. This is a great system and looks very OEM. Definitely consider a lid style system if you aren’t only doing 1/4 mile hits.

      5 Top Rated Questions

      If installed professionally,does this void factory warranty ???

      • This supercharger could affect the factory warranty on your Mustang, we would recommend reaching out directly to your Ford dealer to see how that would affect it though. This supercharger itself does come with a 3-year/36,000 mile warranty as well though.

      what is the typical cost for installation?

      • The cost of installation on this supercharger can vary drastically due to variation of labor costs and the profession of installation. We generally say a supercharger kit will cost somewhere between $1000-$1500 for installation.

      Helpful (8)

      Would the stock engine be able to hold the extra power?

      • The stock Coyote motor can handle the power of this Roush Supercharger with the proper tune paired with it. However, adding forced induction will put some stress on the internals of the motor and will expect them to ware down over time. We recommend looking in to some forged internals which will help handle the power the supercharger will put down on the motor. Superchargers can be confusing and overwhelming sometimes so feel free to give us a call or send an email if you need any additional assistance.

      The description of the product says it’s CARB legal, but in the questions and answers section someone asked if it is CARB legal, you guys answered that it’s not currently legal.

      • The product has since been updated, it is CARB legal per EO Number: D-418-33.
