Muscle cars are known for cheap power. That's practically their founding principle and one that runs back to the early days of the pony car. It's something the Ford Mustang GT tries to carry forward into the modern era, despite how expensive new cars are right now. American tuning company Roush would like to make your Mustang's horsepower-per-dollar ratio come up by a little, and as such has introduced a new supercharger.

It's even got a warranty (three years, 36,000 miles). For $8,500.99, your Mustang could produce up to 750 horsepower and 670 lb-ft of torque. That's as much power as a Shelby GT500. Of course, you'll need some supporting mods to handle that power, but nine grand for GT500 power is still a pretty killer deal.

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.

Roush's site characterizes the installation process as "advanced," and we'd certainly want to have someone do it for us. That's because you need an ASE-certified mechanic to install the kit to get the warranty. Given the extra power your now-almost-GT500 Mustang will be making, you'll probably want it.

For around $9,000, it's certainly not a bad deal, but some money will need to be spent on supporting mods like upgraded tires and brakes. Don't go slapping this one on and turning the key without preparing for the extra power first. We'd hate to see someone feed the "Mustang Bro" stereotype.
