Bone stock, a brand new 2022 ‘Stang with Ford’s 5.0-liter V8 will make 450 hp and 410 lb-ft of torque. This means the supercharger adds 300 hp (or one Volkswagen Golf R) and 260 lb-ft of torque. Mercifully, Roush says the kit is 50-state legal and even lists the kit’s CARB EO number right on the site. Tuning companies have had a tough time adapting to tightening emissions regulations, but it would appear Roush has found a way around it for now.
The kit is optimized for 93 octane fuel (and may even need it to get the above power figures), but it’ll run just fine on 91 octane as well. The kit comes with all necessary hardware, including a new intake and radiator. The kit can work with either an automatic or stick shift Mustang, but you know which one you should be putting it on.
