Hennessey announces 1,035-horsepower Dodge Challenger

The HPE1000 eats Demons for breakfast.

American tuner Hennessey sees the Dodge Challenger as a blank canvas. The firm has released a tuning package for the Hellcat Redeye model that significantly bumps its V8 engine's power output.

The HPE1000 package squeezes 1,035 horsepower and 948 pound-feet of torque from the supercharged, 6.2-liter V8 engine when it's burning race gas. It adds a 4.5-liter supercharger with an upgraded pulley, a new throttle body, long-tube headers, upgraded fuel injectors, and high-flow catalytic converts, among other changes. The result is a hot-rodded Challenger that eats the Demon for breakfast and snacks on Hellcats.

Hennessey hasn't released performance specifications. However, it puts every HPE1000-equipped car on a dyno, and it tests every Redeye it tunes on public roads for up to 200 miles. The conversion is covered by a one-year, 12,000-mile warranty so buyers can rest assured the extra boost won't destroy the V8 engine after two weeks' worth of driving.

Buyers who want to upgrade their Challenger Hellcat Redeye with the HPE1000 package needs to set aside about $35,000 in addition to the price of the donor car. Dodge charges $71,350 for a Redeye with 797 horsepower and 707 pound-feet of torque. Adding Hennessey's modifications bumps the muscle car's price above the $100,000 mark.
