With a massive 797 HP and 707 pound-feet (957 Nm) of torque produced by the 6.2-liter supercharged V8, the Dodge Challenger SRT Hellcat Redeye is anything but powerless.

Nonetheless, Hennessey decided that it needs to have hypercar levels of power and proceeded with upgrading the Redeye with its HPE1000 pack that includes among other parts, a 2.65-liter supercharger system, pulley and throttle body upgrades, high-flow catalytic converters and supercharger bypass valve.

Available for the 2019-2020 MY, it lifts power to 1,035 HP at 6,500 rpm and 948 lb-ft (1,285 Nm) of peak torque at 4,200 rpm. These numbers are achievable when the car runs on race gas, and even more impressively, the Texan tuner claims an outstanding output of 880 HP and 806 lb-ft (1,093 Nm) on the wheels.

To put their money where their mouth is, they strapped the modified Redeye to the dyno during the lab testing phase of the build and set it loose at the track to prove that it’s fast, no matter the surrounding environment.

Without the Hennessey kit, the stock Challenger SRT Redeye has the ability to sprint from rest to 60 mph (0-96 km/h) in just 3.4 seconds, with the factory spec sheet talking of a max speed of 203 mph (326 km/h) and only 10.8 seconds needed to run the quarter mile, on a good day.

The Redeye has a manufacturer suggested retail price of $70,245, $5,000 and $11,000 more than the Hellcat Widebody and regular Hellcat, respectively. The Challenger lineup starts at $28,095.
