The 2019 Challenger SRT Hellcat Redeye is quite a piece of machinery, but after Hennessey laid its hands on it, it’s capable of punishing all Demons.
So, what was the recipe chosen by the Texan tuner for the muscle car? The answer is a 4.5-liter supercharger, high-flow catalytic converters and supercharger bypass valve, upgraded fuel injectors, high-flow air induction system, and a few other parts.
The result is an impressive 1,035 horsepower (1,050 PS / 772 kW) and 948 pound-feet (1,285 Nm) of torque at the crank. Hennessey claims that, at the wheels, the output is 880 hp (893 PS / 656 kW) and 806 lb-ft (1,093 Nm) of torque. Keep in mind that these numbers were achieved on the dyno, and with the car running on race gas.
For the sake of comparison, the supercharged 6.2-liter V8 powering the stock Hellcat Redeye pushes out 797 hp (808 PS / 594 kW) and 707 lb-ft (957 Nm) of torque at the crank. This allows the muscle car to complete the 0-60 mph (0-96 km/h) run in 3.4 seconds, and to max out at 203 mph (326 km/h).
Before setting it loose, Hennessey road-tested their tuned Redeye for 200 miles (322 km), making sure that everything performs as it should. They’ve also fitted it with their own badges, serial numbered plaque and floor mats, and are offering it with a 1-year or 12,000-mile (19,312 km) warranty, whichever comes first.
