The guys at Hennessey have unveiled their HPE650 kit for GM 6.2 liter engines, it can be installed on the 2015 GMC Sierra, the 2015 Chevy Silverado and also the 2015 Escalade. The kit adds a supercharger bringing power up to 665 horsepower and torque up to 658 ft-lb’s (stock is 420 horsepower and 460 ft-lb’s of torque). In dyno testing this translates to 545 horsepower at the wheels! Perhaps even better is the video below, to listen to that supercharger whine! The “Supercharged” badge is also a nice touch in my opinion. This kit will set you back $24,950 installed. For a full parts list scroll below the video.
