Hennessey Performance (HPE) has released another weapon for those determined to outgun all other vehicles on the road. This one is called the
HPE700 Twin-Turbo
Corvette Stingray - and predictably, it goes like stink.
While the stock, naturally aspirated 6.2-liter LT1 V8 under the hood of the Chevrolet is good for a healthy 455 horsepower and 450 pound-feet of torque, the good folks in Texas have moved the game on considerably by bolting on a pair of 62-mm turbochargers and cranking boost pressure up to 7 psi. With dual turbo wastegates, twin blow-off valves and intercooling to reduce the charge temperature, HPE has massaged the engine to produce 707 horsepower and 661 pound-feet of torque. Against a stopwatch, Hennessey says its HPE700 Twin-Turbo Corvette Stingray will hit the 60 mph benchmark in 2.9 seconds (factory stock is 3.8 seconds) and punch through the quarter mile in 10.5 seconds at 135.4 mph. Its top speed is estimated at more than 210 mph.
The turnkey price of an HPE700 Twin-Turbo Corvette Stingray is about $120,000 (including the donor Corvette with the 3LT and Z51 package), and buyers are able to choose whether they want a six-speed automatic or seven-speed manual gearbox and a host of other upgrades including HPE forged monobloc wheels and aerodynamics to provide additional stability at speed. The company expects to build just two-dozen examples, so you might not get to see one for yourself out on the streets if you can't make it to the car's Boca Raton Concours reveal. We've got the next-best thing, though – a burnout video – which you can watch by scrolling below.

Hennessey to Unveil HPE700 Twin Turbo Corvette at Boca Raton Concours
Texas Tuner Transforms America's Sports Car into American Supercar
February 11, 2014
Sealy, Texas-In association with AutoNation, Hennessey Performance (HPE) will display the company's most powerful Corvette Stingray built to date-the 2014 HPE700 Twin Turbo-at the Boca Raton Concours in south Florida. The HPE700 Twin Turbo will be unveiled on the evening of Friday, February 21 at the Boca Raton Airport Hangar Party that kicks off the concours weekend.
The heart of the HPE700 is its twin turbo system that utilizes a pair of precision ball bearing 62-mm turbochargers producing 7 psi of boost pressure. The handcrafted HPE system utilizes mandrel-bent stainless steel tubing throughout, and also incorporates dual turbo wastegates. Twin blow-off valves on the intercooler's TIG-welded aluminum plenum are prominently displayed when you pop the hood, and help keep the turbos spooled with lift throttle, exhaling with that muted whoosh that's music to an enthusiast's ears.
The HPE700 Twin Turbo delivers 707 bhp @ 6,400 rpm and 661 lb-ft of torque though either a 7-speed manual or 6-speed automatic transmission. Equipped with optional 20-inch drag radial tires, the HPE700 Stingray hits 60 mph from a standing start in just 2.9 seconds while blowing through the quarter mile in just 10.5 seconds @ 135.4 mph. Top speed is estimated to exceed 210 mph-faster than the Hennessey C7 Corvette that broke 200 mph on a Texas toll road back in December of last year.
"We've taken America's sports car and transformed it into an American supercar," said company founder and president John Hennessey, "and it's a testament to the soundness of Corvette engineering that the new Stingray not only copes with this massive infusion of power, it seems to thrive on it."
Power is nothing without control, and at higher speeds, Hennessey's CarbonAero™ carbon-fiber front spoiler, side sills and rear lip spoiler provide additional overall downforce to this steroid-injected Stingray. "I'd describe the look of our HPE700 Twin Turbo with CarbonAero™ bodywork as being tastefully aggressive," said Don Goldman, CEO of Hennessey Performance. Completing the vehicle are 10-spoke Hennessey H10 forged monoblock wheels, which accept the factory Michelin Pilot Super Sport tires. Compared to the Z51 Package wheels, the set of Hennessey H10 alloys reduce weight by over 19 lb., significantly reducing both rotational mass and unsprung weight for improved acceleration and handling.
With a turn-key price tag of nearly $120,000 (including the base Corvette Stingray with 3LT and Z51 factory options), the HPE700 Twin Turbo does not come cheap. However, the company offers a comprehensive powertrain warranty for its Corvette upgrade systems, while delivering a level of performance on par with European supercars like the Lamborghini Aventador and McLaren MP4-12C.
The company plans to produce just 24 examples of the HPE700 Twin Turbo Corvette for the 2014 model year, ensuring that HPE700 owners not only have one of the fastest C7 Corvettes on the road but also one of the most exclusive. Said Don Goldman: "The HPE700 experience is a rush, and will absolutely ruin driving a stock Stingray...there's just no going back."
