Thanks to a custom twin-turbo, this Mustang GT500 produces over 1,200 hp on the dyno.
Most people would agree the 2020 Ford Mustang Shelby GT500 has more than enough grunt. In stock form, Ford's 5.2-liter supercharged V8 pumps out 760 horsepower and 625 lb-ft of torque, which is sent to the rear wheels through a seven-speed dual-clutch automatic transmission.
That's an excessive amount of power in a road car for most people, but it didn't take long for aftermarket tuners to extract even more power from the new GT500, taking the high-performance muscle car to new levels of insanity. Last month, the Texas tuning wizards at Hennessey Performance unveiled the new Venom 1000 package that cranks the GT500's V8 up to 1,000 hp and 850 lb-ft.
Now, Palm Beach Dyno has shown off what the car's owner claims to be the most powerful 2020 Ford Mustang Shelby GT500 on the planet. Based on the numbers, we're not going to doubt them. Under the hood is a Hellion twin-turbo installed by the Ohio-based tuning shop RaceMod. A bolt-on kit is also in development with no customization required if you don't want to get your hands dirty.
To find out how much power this beast produces, the modified GT500 was hooked up to the dyno. On the first run at 5 psi of boost, the GT500 generates 711 hp and 540 lb-ft. Cranking up the boost pressure to 12 psi increases the power to a very respectable 944 hp and 691 lb-ft.
If that's still not enough power for you, the customized GT500 produced 1,145 hp and 817 lb-ft when the boost pressure was increased to 17 psi. In the final run, the boost pressure is increased to 20 psi, and the sound is deafening. Palm Beach Dyno expected the GT500 to hit around 1,220 hp and 850 lb-ft, but was pleasantly surprised when the result came in at a staggering 1,252 hp and 867 lb-ft. That makes this GT500 even more powerful than a Bugatti Veyron.
Dyno tests aren't always 100-percent accurate, but it hopefully won't be long until the 1,250-hp GT500 gets taken for a spin so we can find out how this massive power increase affects the performance. It should be capable of hitting 0-60 mph in well under three seconds and set some blisteringly quick quarter-mile times, so we can't wait to see it in action.
