And here it is testing on the dyno.
When you first think of Hennessey Performance, cars like supercharged Corvettes, Camaros, and Cadillacs often come to mind. Then there's also the Venom GT. No explanation is needed here. But the Texas-based Hennessey also performs upgrades for SUVs, like the Escalade, as well as pickup trucks. Yes, trucks. One example is this: the 2014 HPE500 Supercharged GMC Sierra. Power comes from a 5.3-liter V8 that now produces over 500 horsepower.
Along with the supercharger, this was accomplished thanks to a high flow intercooling system and engine management calibration. There are also the typical Hennessey badges throughout. And yes, it sounds awesome on the dyno.
