Hennessey Says Goodbye To Dodge Challenger And Charger With 1,000-HP Upgrade

To get these dodges up to the HPE-1000 spec, the company fitted both with upgraded superchargers, intercoolers, and pulleys. Both the Charger and Challenger received high-flow catalytic converters, stainless steel headers, and an upgraded crankcase ventilation system.

The company assures these upgrades were installed professionally, which is why they’re backed up by a three-year/36,000-mile warranty, whichever comes first. HPE-1000 builds are track-proven and undergo a total of 500 hours of testing to make sure they are up to snuff. In fact, the brand says that the cars shown in the video are performing some of the same antics that form part of the company’s “validation testing.”
