Hennessey performance has another video out, this time showcasing the incredible engine noise of the Corvette ZR1.
You might remember Hennessey Performance from such special projects as the 1,000 hp “Exorcist” Camaro or the rocket-powered living room of a Jeep Trackhawk with an equally ludicrous 1,000 hp. Hennessey really likes their cars to break the 1,000 hp mark.
Now we have yet another video from the same tuning house that thinks every car needs a supercharger. And they’re not wrong.
According to the video’s description, this is a stock 2019 Corvette ZR1 that is due to be upgraded. Before they do, however, the fine folks at Hennessey decided to take it out to their test track for a little spin to see how well the Chevy engineers did their jobs.
As it turns out, they did a pretty good one. We only really get to hear the ZR1, but the sound of the 6.2-L supercharged LT5 V8 engine is a thing of beauty. This is the 7-speed manual, and while the shifts are still slower than what the automatic can perform, they’re still plenty fast and entirely on point.

In its raw form, the ZR1 boasts 755 hp, 715 lb-ft of torque, and a zero to sixty time of around 3 seconds. Hennessey Performance offers three different ZR1 upgrades, all denoting the new power level that the Corvette achieves by the time they’re done.
The HPE 850 upgrades the car’s headers, valves, catalytic converter, camshaft, and more to eventually give the car 850 hp and the same amount of torque as before. A few tenths of a second get shaved off the zero to sixty time, but that’s about it.
On the HPE 1000, a larger supercharger is installed to bring power to Hennessey’s preferred 1,000 hp and 966 lb-ft of torque. Zero to sixty is reduced to 2.5 seconds.
Finally, the HPE 1200 bores out the engine to 7.0-liters and increases power to 1,200 hp and 1,066 lb-ft of torque. Zero to sixty is now an eye-watering 2.3 seconds, with an estimated top speed of over 230 mph.
We’re still waiting to hear what that beast sounds like, but when we do we’ll be sure to let you know.
