Watch A Ram 1500 TRX Get Obliterated In A Drag Race

The Mammoth 900 has a clear power advantage in this race since Hennesseydynoed a stock TRXat 583 hp and 571 lb-ft after calculating drivetrain loss. But although the Mammoth is entering the drag race with bigger guns, it's also wearing larger tires. Hennessey equipped the truck with 20-inch wheels wrapped in 37-inch tires, which are heavier than the standard 18-inch wheels with 35-inch tires.

年代o do the wheels and tires hinder the Mammoth's performance in a significant way? Nope. The Hennessey-tuned TRX takes the lead from the get-go and holds it until the end of the quarter-mile. The gap by the end is sizable.

This result is not at all surprising, but we were a bit perplexed to see such a commanding victory even on such large tires. If the Mammoth 900 package isn't crazy enough for you, Hennessey will offer alimited edition Mammoth 1000producing 1,012 hp and 969 lb-ft of torque. Hennessey says this will be the quickest truck it has ever produced, hitting 60 mph in only 3.2 seconds. The tuner only plans to build 200 examples priced at $135,650.
