After owning your 707 horsepower Dodge Challenger Hellcat for a little while, you might become a bit used to the power at your disposal and seek something more. If you find yourself in this predicament, you could pay a visit to Texas-based tuners Hennssey Performance, who offer 800, 850 and a 1000 horsepower upgrade packages for the muscle car.
To demonstrate the capabilities of their HPE850 upgrade package, Hennssey lined up an HPE850 Challenger Hellcat next to a stock 707 horsepower Hellcat and had a drag race. The HPE850 kit consists of a new ECU, a new lower pulley for the supercharger, a port matched throttle body and a high flow air filter.
These upgrades allow Hennessey’s Challenger Hellcat to properly walk all over the stock car. Check it out in the video above, and click here for additional information on Hennessey’s HPE850 upgrade kit for the Challenger Hellcat.
