This 4WD Demon Can Barely Be Held Back!
How many safety straps does it take to contain a beast? All of them! The new Hennessey Mammoth 900 screams on the dyno in order to validate their latest offering, and it combines all the innovations unleashed on their Charger and Challenger packages.
Starting with the top end, the team adds more fuel with new injectors to handle more boost. The supercharger is treated to a new snout with upper and lower pulleys before 200 miles of road testing. Once the tune was safe on the street the most successful dyno run yielded 728 horsepower and 679 lb-ft of torque. Almost 150 horsepower over what it made from the factory, you will keep Raptors in your rearview.
