Hennessey Hellcat hits 852 hp

2016 Hennessey HPE800 Charger Hellcat

Four-door Mopar land rocket receives additional boosters

The horsepower output offered by the Dodge Challenger SRT Hellcat and its four-door Charger sibling is enough for most people, but Hennessey Performance is not most people. The ridiculously dynamic duo already pumps out 707 hp courtesy of their 6.2-liter supercharged V8 engines, but in the performance tuning world there is still room for improvement, never mind the fact that there aren’t many places to exercise all those horses.

Enter the HPE800. The Hennessey version of the HellcatĀ dials up the horsepower rating to 805 hp, presumably for Bond villains who suspect that they could at one point be pursued by stock Hellcats. The company accomplished this via the addition of an upgraded lower pulley that bumps boost by 1-2 psi, a high-flow air filter, a port-matched throttle body and an ECU tweak. In other words, not a lot of hardware, which suggests that SRT engineers were being a little conservative in the interest of tire, engine and life preservation.

If 805 hp is still a bit mild for you, there is the option of the HPE850 which has been tuned to produce 852 hp. This upgrade package includes all the gizmos of tthe HPE800, but adds a ported supercharger housing (in case you expect to be pursued by stock HPE800s in a Michael Bay movie).

All versions of the Hennessey Hellcat will receive the company’s badging to let stock Hellcats know they shouldn’t bother racing them, headrests with embroidered Hennessey Performance logos and plaques on the engine and dash.

What other land rockets are on the menu at Hennessey? Well, there’s the 1000-hp Cadillac CTS-V that the company showed off in April of this year, and now that gas is cheap again there’s an homage to the Ford Excursion in the form of the Hennessey VelociRaptor. We picture the latter being in demand among unshaven mercenaries wearing body armor.
