Corvette fans were excited when the 2015 Corvette Stingray claimed 450 horsepower. Earlier this month, the new C7 Corvette Z06 stunned the crowd even more when it boasted 625 horsepower. However, back at Hennessey Performance, the Z06 didn't take it far enough.

The Texas-based performance shop takes a standard Corvette Stingray and adds another pair of turbochargers for extra power. Other goodies that come with the HPE700 Twin Turbo package include fuel system upgrade, stainless steel inlet piping, dual wastegates, intercooler, stainless steel turbo downpipes, stainless steel exhaust system. Of course, the technicians at Hennessey Performance will take care of the engine management calibrations, dyno tu ning, and road testing. Did we mention that the HPE700 Twin Turbo Corvette Stingray will also come with a warranty?


The twin-turbo Hennessey HPE700 Corvette Stingray effectively dishes out 708 horsepower at 6,300 rpm, more than 80 horsepower more than the standard Z06. Hennessey Performance also made sure the HPE700 Corvette Stingray looked as much of a monster as it actually is by offering a Hennessey CarbonAero package including a front lip, side skirts, and a rear lip spoiler. Hennessey H10 Monoblock wheels are available as well. Finally, a Brembo carbon ceramic brake kit and an Penske adjustable suspension upgrade will ensure the HPE700 Corvette Stingray can stop and turn as well as it goes.


The video below shows the Hennessey HPE700 Corvette Stingray strapped to a dyno. With a mild 7 psi of boost and 93 octane fuel, the HPE700 is posted a 608 horsepower, a fair read-out considering the 15 percent drivetrain loss.
