Hennessy Is Bringing 2,875 Horsepower Worth Of Lusty Machines To SEMA

John Hennessy’s explanation for this: “Being fast matters.”

John Hennessy is a man with simple pleasures; after all, he just wants to go fast. His most notable attempt at this is the Hennessy Venom GT, a maniacal car that embodied Carol Shelby’s philosophy of putting a powerful American engine into a light British roadster. The car was even clocked at 270.49 mph once, faster than the 267.8 mph top speed of the Bugatti Veyron Super Sport. Now, Hennessy wants to take things a step further by introducing an upgraded version of the Venom GT at this year's SEMA show.

No surprise, the only upgrade to the car is a bump in horsepower from 1,244 hp to an incredible 1,451 hp. Hennessy claims that this raises the top speed from 270 mph to a theoretical 280 mph, and while we want to see proof of this, a 10-mph bump in top speed seems plausible given the extra 207 horsepower. The upgrade comes from the GM-sourced 7.0-liter twin-turbo engine’s ability to drink E85 ethanol, which allows for the Texas tuning company to safely raise the boost pressure from 19 psi to 26 psi. Hennessy will also bring two 5.0-liter supercharged Fords to the show, a 774 horsepower Mustang convertible and a 650 horsepower VelociRaptor.
