Supercharging a car is a great way to add power. You can have much more power when needed, without the fuel mileage sacrifices of a larger engine. But, while it may seem like a no-brainer, supercharging is expensive and time consuming.
Automakers rarely supercharge these days because of the many hours of testing required, and the resulting increase in power has the potential to stack up warranty repairs for clutches, axles and transmissions. For the end user, supercharging a daily driver would be a nightmare of modification and upgrades.
Enter John Hennessey. From the beginning it has been his mission to push each car to the limit.

Picking up where Chevrolet left off, his new HPE650 Supercharged Upgrade generates more horsepower and torque than the base 2015 Corvette Z06. Developed on the dyno and at their own quarter mile facility in Sealy, Texas, the team at Hennessey Performance has combined and validated a complete package. Their proprietary supercharger is installed, along with intake and cooling system upgrades, to deliver 650 horsepower.
Looking at the dyno graph from a May 27 press release, this car creates the same amount of power as a stock stingray at only 4,000 rpm, and screams to a 6,300 rpm redline. As with Hennessey Performance’s other creations, drivability has not been sacrificed. Only 100 units are being produced for 2014, and each is backed by a 3 year/36,000 mile warranty. Hennessey has done all the hard work, all he needs are your keys.
