Late-model Ford Mustang owners with a 5.0-liter V8 have a new way to get supercar power under their hood. Roush Performance just released its new supercharger kit and it’ll pack 750 ponies (559 kW) under the hood. The extensive kit contains hardware and software changes and comes with a three-year or 36,000-mile warranty too.
The kit works specifically with 5.0-liter V8-equipped Mustangs from 2022 and 2023. In stock form, those ponies make 450-480 hp (335-357 kW) depending on trim along with 410 lb-ft of torque and trim is important in this context. The Roush Performance supercharger kit won’t work on the Mustang Mach 1, Bullitt, or the GT350 so you’ll need a base GT to start.
With that foundation, the kit adds an Eaton TVS R2650 supercharger with its four-lobe rotor design capable of 14 pounds of boost. Roush also includes its own low-temperature radiator to keep the engine safe. The tuner says that the kit requires some 16 hours worth of installation time and that a software update is required to optimize the changes.

Once complete, the dyno results speak for themselves. The finished engine should produce about 750 hp at around 7,000 RPM and 670 lb-ft of torque at 4,800 RPM. What’s perhaps most impressive is that just as the torque starts to fall off the horsepower picks up and continues to climb all the way to redline.
It’s worth noting that the kit isn’t compatible with 5.0-liter Mustangs that are equipped to meet Euro 6.2 emission standards. In addition, it’s not even for sale or available for installation in California or any other state that requires an EO number. Thankfully, in states where it’s legal (most of them), it’ll work regardless of transmission.
Roush backs this package as it does with many other of its products. That means it’ll be covered for three years or 36,000 miles so long as it’s installed by an ASE-Certified technician. The kit runs $8,799.99 which seems like a pretty sweet deal for nearly Shelby GT500 (760 hp / 566 kW) levels of power.
