Horsepower is actually pretty cheap these days. You can walk into a Dodge dealer and get a sedan with 707 hp. Soon, the engine that makes that crazy amount of power will be in an off-road pickup truck. Ford can crank 332 hp out of a 2.3-liter turbocharged four-cylinder–not to mention the 800-hp Dragon Snake concept–and the new GT500 can out-muscle a few supercars. And with 760 hp, it’s more powerful than any Dodge Hellcat. But it’s also $74,000. Luckily, there’s Roush, the tuner behind the 650-hp F-150 Nitemare and Tactical Edition. And the latest Roush Mustang has the boost to handle some Hellcats.
Roush Mustang Stage 2 supercharger details
Normally, the 5.0-liter V8 in the Mustang GT makes 460 hp and 420 lb-ft. To give it more go, Roush, installed an Eaton TVS R2650 roots-type supercharger and reprogrammed the ECU. When running on 93-octane, Roush’s Phase 2 kit lets the Mustang develop 750 hp and 670 lb-ft.
But Roush also made sure the supercharged Mustang would be durable. Roush’s Phase 2 kit also includes a high-capacity radiator, as well as strengthened bearings and timing gears. It’s also 50-state emissions-legal.
How the Roush Mustang Stage 2 supercharger lets the Mustang compete
Normally, a Mustang GT hits 60 in as little as 3.9 seconds, according to Motor Trend. However, simply adding power doesn’t always make acceleration better. For example, the GT500 has more horsepower than the Z51 Corvette, but the Corvette hits 60 sooner. Even with 760 hp, the GT500’s 0-60 time is 3.5 seconds—the tires just can’t get any more grip.
So, the Roush Phase 2 supercharged Mustang may not necessarily be a match for the GT500. But it’ll almost certainly out-accelerate the Toyota Supra. Even the Dodge Charger Hellcat Widebody will likely be slower: its 0-60 time is only 3.8 seconds.
The Charger Hellcat Redeye is slightly faster and more powerful. Its 6.2-liter supercharged V8 puts out 797 hp and 707 lb-ft, letting the mad muscle car hit 60 in 3.4 seconds. Considering that’s faster than even the GT500, the Roush Stage 2 supercharged Mustang probably won’t be able to beat it in a drag race. But it’ll almost certainly give the Charger Redeye a run for its money.
Speaking of money, the Roush Mustang will be cheaper than the Redeye.
Pricing and availability
The Roush Phase 2 supercharger kit costs $7999, not including the cost of installation, which can be done at any Roush-authorized Ford dealer. The kit can be installed on any 2018-2020 Ford Mustang, except for the Bullitt. And unfortunately for EU customers, the Roush kit is incompatible with the particulate filters needed to meet emissions standards.
A Roush Phase 2 supercharged Mustang, then, can be yours for as little as $45,000. That’s significantly less than the GT500 ($74,000), Charger Hellcat Widebody ($71,745), and Charger Hellcat Redeye ($72,295).
Oh, and unlike all those other high-power muscle cars, you can get the Roush Mustang with a stick.
