Hennessey Tunes 2020 Ford Mustang Shelby GT500 Up To 1,200 Horsepower
850- and 1,000-horsepower models are also available.
The 2020 Ford Mustang Shelby GT500 hasn't landed in showrooms yet, but Texas-based tuner Hennessey already has packages ready to crank up the power on the super Stang.
While the GT500 proudly stands as the most powerful factory-built, street-legal Mustang ever released by Ford, Hennessey's Venom 1200 blows it out of the water with a twin-turbocharged V8 that delivers 1,200 horsepower at 7,000 rpm. To add context, the stock GT500 delivers 760 horsepower.
Hennessey pegs the maximum torque output at 1,000 pound-feet when the tachometer indicates 4,800 rpm. Achieving those figures was easier said than done. The tuner explained its engineering department upgraded a long list of parts including the intercooler, the fuel delivery system, the induction system, and, crucially, the pistons and the connecting rods. On top of that, the Venom 1200 requires E85 or 109-octane race gasoline.
The V8 spins the rear wheels via a seven-speed, dual-clutch automatic transmission that has also been strengthened. Hennessey hasn't released performance specifications yet, but the 440-horse bump should make the Venom 1200 a force to reckon with on the drag strip.
