Watch the Hennessey Performance Twin-Turbo Corvette Stingray on the Dyno


This sounds really, really mean.

The new Chevrolet Corvette Stingray is not a car to take lightly. Its performance is outstanding and it looks fantastic. The new Corvette Z06 takes things even further with its supercharged LT4 V-8 engine that is expected to spit out 625 horsepower and 635 lb-ft. of torque. Hennessey Performance has a different way of making the Corvette even faster with their new HPE700 twin-turbocharger upgrade that is pushing 700+ horsepower.

The new HPE700 twin-turbocharged Chevrolet Corvette Stingray includes a pair of twin ball-bearing turbochargers that feed about 7 PSI of boost pressure to the 6.2-liter LT1 V-8 engine. The limited-edition upgrade comes with a new air-to-air intercooler, dual wastegates, dual air induction filters, stainless steel inlet piping, and an HPE engine management system. The exhaust is also all-new with the addition of a full stainless steel system with dual turbo downpipes to reduce backpressure as much as possible. After dyno and road testing, the car is capable of producing 708 horsepower at 6,300 RPM.

On the dyno, the HPE700 twin-turbocharger Corvette Stingray threw down a whopping 608 rear-wheel horsepower on 7 PSI and 93 octane fuel.

The HPE700 upgrade program can also be paired up with in-house carbon fiber aerodynamics and monoblock wheels. New Brembo carbon ceramic brakes, a Penske adjustable suspension, and custom leather and carbon fiber interior fittings can also be installed.

The new HPE700 twin-turbocharged C7 Corvette Stingray upgrade will be limited to just 25 units for 2014, and comes with a one-year/12,000-mile limited warranty.
