For most, the 650 horsepower offered by the Chevrolet Corvette Z06 is more than you’ll ever need in a front-engined, rear-wheel-drive sports car. However, for the rarefied buyer out there that demands even more power—much, much more power in some cases—there are companies like Hennessey Performance that endeavor to meet such needs.

Here we see Hennessey testing a new 1,000-horsepower—yes, one thousand horsepower—package for the Corvette Stingray. While it looks stock on the outside, almost all of the drivetrain components have either been swapped out or reinforced in order for the car to safely and reliably handle upwards of 1,000 hp.

Hennessey develops such power using either supercharging or turbocharging, depending on the buyer’s preference, with the version being developed here relying on a supercharger. This is no bolt-on job as Hennessey rebuilds the entire engine using a host of forged, lightweight elements. The tuner also upgrades all of the cooling systems and retunes the ECU to ensure everything works smoothly.

As the video indicates, the car sounds insane. Better yet, a quick look at its dyno chart shows a wide, relatively flat torque curve and a nice linear power curve, which should translate to steady, predictable power delivery out on the road or track. Hennessey is still fine tuning the package but already we can see that it’s producing close to 850 hp at the wheels, which should translate to around 1,000 horses at the crank.

You can't buy this package just yet but if you’ve got a new Corvette and are in need of upping its game right now, Hennessey has upgrades available that lift output to 700 hp. However, for those lucky Corvette Z06 owners, Hennessey already offers a 1,000-hp package for your ride.
