On the very same afternoon that Hennessey Performance Engineering managed to get their HPE600 Corvette Stingray past the 200 mph mark on a closed off section of the Texas Toll Road, the team hit an incredible 163 mph in their supercharged HPE600 Chevrolet SS.
The HPE600 Package includes a TVS2300 Supercharger system, a custom HPE pulley, high flow fuel injectors, a custom HPE engine and fuel management system and more. The upgraded SS hits its 163 mph top speed with ease, as Hennessey claims the car is limited by its gearing.
Hennessey has big plans for the Austrailian made SS, with HPE 650,800 and twin turbocharged HPE1000 upgrade packages listed on their website. They might want to take care of that gearing issue first though.
