Here’s another tuner that has recently got their hands on the 2014 Corvette Stingray. Hennessey Performance announced early on their plans to upgrade the new C7 Corvette and that process begins with doing a baseline dyno test of the car.
Hennessey says the Black Stingray is a bone stock 3LT 6-speed auto with the Z51 Performance Package. The video shows the Corvette Stingray put down 399-rwhp and 400 ft-lbs of torque. That’s slightly less than Lingenfelter Performance Engineering’s dyno test which saw a Z51 7-speed Corvette test at 416-rwhp and 416 ft-lbs.
Back in July, Hennessey released an aggressive list of upgrade packages for the Corvette Stingray. Those packages ranged from a 600 hp TVS supercharger upgrade priced at $12,495 to a 1,000 hp system consisting of a HPE custom forged engine priced at $67,950.
