Watch The Hennessey Venom 1200 Mustang GT500 Put Down 1000 HP On The Dyno

Just in case a factory spec 760 bhp Ford Mustang Shelby GT500 isn’t quite enough for you, and you have a craving for more power, why not take a look at one of the most powerful Mustang-based cars Hennessey ever offered, the 1,204 bhp Venom GT1200, adding another 200 bhp to the already incredibly fast Venom 1000.

Straight from the factory, a Shelby GT500 comes with a hand-built supercharged V8 with a 5.2-liter displacement, delivering a healthy 760 bhp and 625 lb-ft of torque, making it the most powerful engine ever fitted straight from the factory in a Mustang, but it seems Hennessey found a lot more power hiding in this configuration, about 58% to be exact, by fitting a higher capacity 3.8-liter supercharger, a high-flow induction system, new fuel rails and injectors, and an air/oil separation system. They continue with custom fittings, lines, and belts, while the stock tensioners are upgraded, and the dual-clutch transmission is recalibrated for its high-output role.

Each Venom 1200 is fine-tuned on Hennessey’s in-house dynamometer, before being taken onto the road for further shakedown testing, when the car is finally ‘released’ by the test driver and is ready to leave Hennessey Performance, its comprehensive upgrades and enhancements have unleashed a formidable 1,204 bhp and 902 lb-ft of torque, a massive increase compared to the factory original numbers.
