It has a 6.2-liter V8 engine that makes 707 hp and goes 0-60 in 3.4 seconds. As such, the Dodge Charger Hellcat should not leave much to be desired, should it? As you can imagine, the Texan answer to this question is 'no,' which is why Hennessey Performance has just given the world its HPE800 upgrade package. With a new ECU and upgraded tuning software added, the tuner has also performed a lower pully upgrade to increase boost, added high flow air filters and thrown in a port matched throttle body. The results? Insane, as expected.

The Hennessey Charger Hellcat HPE 800 will now supply its owners with 805 horses at 6200 rpm. To complement this performance, the tuner has also added some extra appearance accessories, including Hennessey embroidered headrests, Hennessey and HPE800 badging, and serial number dash and engine compartment plaques. For those who are still unsatisfied, rest assured that an HPE850 upgrade is also on the way, featuring a mind-blowing 852 hp. The cost of these upgrades has not been revealed, but you will have to bring your Charger SRT Hellcat yourself. Similar packages are also available for the Challenger SRT Hellcat coupe.
