It’s no secret that Hennessey likes to supercharge GM Small Block V8 engines, mostly Corvettes. And recently, the Texas tuning company took an example of an HPE700 Corvette Stingray on the dyno. As you would expect, the results are good, but some numbers need explaining.
As you can see in the video, it says the HPE700 makes 610 horsepower and 557 torques. Why not call it the HPE 610, you ask? That’s because it makes 700 horsepower to the crankshaft, and not the wheels. A dyno measures what is being sent to the wheels and successfully put down on the road.
To compare, the 2015 Corvette Z06 will make about 650 crank horsepower and torque, but hasn’t been dyno tested yet. Nor has it been priced. Comparatively, the HPE700 costs around $120,000 when factored in with a loaded Stingray, of which Hennessey only built 24 for the 2014 model year. And as if this special Stingray didn’t look threatening enough, Hennessey decided to throw on some subtle details, such as blackened writing and stripes, for good measure.
