What happens when you twin-turbocharge a 707-hp Hellcat? 1,023 hp, that’s what

Hennessey HPE Challenger Hellcat

Sprint, drag times drop dramatically with overhaul to Charger and Challenger

When a supercharger isn’t enough, add turbos. At least that’s the Hennessey Performance formula.

The Texas tuner pushes both the Challenger and Charger Hellcat to a whopping 1,023 hp at the crank, along with 987 lb-ft of twist, for its new HPE1000 package. Is it overkill? Sure. Would we still be stoked to drive and own one? Absolutely. Those go-fast parts bring the 0-60 time down to 2.7 seconds and the quarter-mile down to 9.9 seconds from 11.2 … both achieved with drag radials, by the way. Your times may vary.

In addition to the 15 psi boost from the turbos, Hennessey adds a high-flow air-to-water intercooler, stainless steel headers, dual turbo wastegates, new plumbing, high-flow fuel injectors, an upgraded fuel pump and more. As for visual effects, the Hennessey Hellcats come with new HPE1000 badges, side and rear; a serial plaque signed by John Hennessey and the tech who did the work; and premium floor mats, baby!

This monstrous upgrade costs a stout $55,000 for either Charger or Challenger. Of course, that’s on top of the price of a base Hellcat — $67,645 for the Charger and $64,195 for the Challenger. Turnaround time is about four-six months.

Just 12 of each will be built, so go to hennesseyperformance.com for more information … and send a check.

Let us know when it arrives.
