Hennessey’s H1000 upgrade for the Dodge Challenger Hellcat transforms an already legendary muscle car into a true powerhouse. Pushing output to an astonishing 1,000 horsepower and 948 lb-ft of torque, the H1000 package delivers jaw-dropping acceleration and relentless top-end speed. Thanks to a high-flow supercharger system (non-redeye models only), upgraded fuel injectors, a high-performance air induction system, and a custom engine calibration, the H1000 Challenger isn’t just faster — it’s an entirely different breed of American muscle.

Beyond raw numbers, the H1000 upgrade amplifies the Hellcat’s aggressive personality with enhanced sound, sharper throttle response, and brutal performance both on the street and at the track. Every H1000 Challenger is built with Hennessey’s signature attention to detail and backed by a limited warranty, offering customers the ultimate combination of power, reliability, and exclusivity. This is the Hellcat as it was always meant to be: louder, faster, and absolutely unforgiving.
