While the Ford (F) 2020 Mustang Shelby GT500 boasts a powerful 760 horsepower and 625 pounds-per-feet of torque, it can now be made even more powerful with some upgrades offered by Hennessey. Hennessey is offering big horsepower boosts for the GT500 with its Venom 850, 1000, and 1200 kits.

With the Hennessey Venom 850 tuner kit, the GT500 can see ratings of 850 horsepower and 725 pounds-per-feet of torque. Those car enthusiasts looking for even more power can jump into the Venom 1000, which offers 1,000 horsepower and 850 pounds-per-feet of torque.

At the top of the power line is Hennessy’s Venom 1200 option, which offers 1,200 horsepower and 1,000 pounds-per-feet of torque at 4,8000 rpm.

To harness the added power, Hennessey takes the V8 to a twin-turbo setup and uses an enhanced fuel system along with bigger pistons and rods, according to Motor 1. A stainless-steel exhaust is also integrated along with an upgraded cooler, and high-flow induction system to complete the engine modification, the news outlet said.

With the added power of up to 440 horsepower, Hennessey also reportedly modifies the transmission to handle the power. Hennessey said it also provides a one-year/12,000-mile warranty and test drives the modified GT500 as far as 150 miles for quality assurance.

The Venom packages also come with badging and logos, plaque and embroidered headrests to complete the look.
