Hennessey Mammoth 1000 Ram TRX Floggs Their Dyno

Thats a ton of torque! Hats off, its time to salute the Dyno Room at Hennessey Performance. It has been subjected to millions of horsepower over the years, and their latest Dodge Ram TRX has an achievement unlocked. With their special blend of boost and tuning, it has proven to be a consistent badass. Mild-mannered in traffic, they loaded the rollers to simulate highway rolls to dial-in the transmission for more power. This prototype will form the basis for the Mammoth 1000 SUV, with seating for 7 and 761 horsepower at the ground. Torque at the tires is a blistering 701 lb-ft, and it does this without E85. Your Dodge, Jeep, Ram, & Chrysler Hemis can also be treated to Hennessey upgrades ranging from mild to wild. Click the button to learn more and stay with us for all your Hennessey news. Learn More

Hennessey Mammoth 900 TRX vs Stock Ram Drag Race

How fast would you be with an extra 200 horsepower? Spring 2021, with the outbreak on the mend we find ourselves in a war for truck supremacy. The wizards at Dodge have cooked up a wild beast with 702 horsepower, but that doesn't cut it in Texas. To see how their upgrades perform in a real-world setting, let's watch the Hennessey Mammoth 900 TRX vs a stock, unmodified one. RAM TRX Horsepower and Specs Making more boost and adding fuel was where it started. After miles of testing and several dyno sessions, the boss was happy with 728 horsepower and 679 lb-ft of torque at the wheels. Speaking of, those 20" Hennessey forged monoblocks are wrapped in 37" rubber. This fancy footwear was meant for serious off-roading so how does it compare to a showroom-fresh model? Tuning a truck that is safe for hard work was done by towing Mr. Hennessey's Heritage Mustang around the Pennzoil Proving Grounds, so the Mammoth's abilities speak for itself. Send your new TRX to Houston and you won't be disappointed. The 1,000 horsepower package will be completed soon, so stay with us for all the details. RAM TRX FOR SALE

2021 Ram TRX Arrives at Hennessey Performance

Hundreds of Hellcats have left Houston with incredible power, so we're happy to see a 2021 Ram TRX has arrived at Hennessey Performance. In order to get a baseline for tuning and performance, Alex and his team attempt to shakedown the 702-horsepower pickup. For a frame of reference, the Jeep Trackhawk uses the same Hellcat V8. Without touching the heads or cam the HPE1000 series offers 1,012 horsepower and 969 lb-ft of torque. Without the weight of the big SUV, the Mammoth 1000 is potentially a truck that offers consistent 9-second timeslips. A 3rd-generation VelociRaptor is also in development, so tell us which one you would drive in the comments below.
