750HP! Roush Stage 2 FORD MUSTANG Supercharger (2018-2021) 5.0 GT

Ford Mustang Roush Supercharger Kit

The Coyote in the 2018, 2019, 2020 and 2021 Ford Mustang GT is capable of some serious power from the stock long block. Roush, a famous Ford tuner, knows this and created a bolt on supercharger kit that lets you make significantly more horsepower and torque over stock without having to build an all motor beast. Roush takes the stock 5.0 V8 and gives it a gain of 290 horsepower over the stock setup – how does 750 horsepower and 670 ground pounding torque sound? AWESOME!

Roush includes supporting mods such as a high capacity, high flow radiator to lower temps and keep everything cool and safe. This radiator is designed to give track cars the added cooling capacity to stay within temp range lap after lap.

The Roush Supercharger, considered their Stage 2, or Phase 2 kit, works with both manual and automatic transmissions and is optimized to be run on standard 93 octane. Sorry if you live in a state with 91 octane like we do – your power generation will be slightly lower.

So with all of this added power, your Mustang will now be unreliable right? Wrong! Roush stands behind their supercharger kit and gives you peace of mind with an industry leading 3 year, 36,000 mile limited powertrain warranty.
