The 2019 C7 Corvette ZR1 is weeks old from its proper debut, but Hennessey Performance Engineering has already announced plans to pull more power from the car. And you thought 755 horsepower was enough.
HPE listed the HPE850, HPE1000 and HPE1200 upgrade packages for Chevrolet’s range-topping Corvette and they come with some major upgrades. Starting with the lowest-rung model, the HPE850 adds upgrades such as a modified lower pulley, high flow cylinder heads, upgraded valve springs, intake and exhaust valves and new pushrods and lifters. Power at the crank is, as the package suggests, 850 horsepower.
Moving to the HPE1000, the biggest change is a different supercharger to boost power to 1,000 hp. Similar upgrades are found elsewhere from the HPE850. Now, the HPE1200 has a really big change: a 7.0-liter V8 engine. Coupled with a larger supercharger, the package will bump the ZR1’s power figures to 1,200 hp and 1,066 pound-feet of torque. Additionally, HPE will back each package with a 2-year/24,000-mile warranty, save for the 1200 package. A one-year/12,000-mile warranty applies to it.
The Corvette team already feels like they’ve calibrated the ZR1 just right to hit a sweet spot, but we’re certain HPE will have some takers.
