2021 RAM TRX HITS THE DYNO, PRODUCES 583 HP TO THE WHEELS: VIDEO

Don’t Worry, This Is To Be Expected

The 2021 Ram 1500 TRX is a seriously impressive truck in every way, but the massive 702 hp Hellcat V8 under the hood is clearly its standout characteristic. The Ford F-150 Raptor is a fast truck, but the TRX really takes things to the next level, with power rivaling many supercars. Now, Hennessey Performance Engineering have put that power to the test on the dyno, and at first glance, the results are troubling. 

That’s because the 2021 Ram TRX Launch Edition they tested only put out 583 hp to the wheels. It’s still a hearty sum of power in any vehicle, but it’s hardly the quoted 702. But when you consider the fact that the dyno measures wheel horsepower and the manufacturer figure is claimed from the crank, it all makes sense. 

Typically, vehicles see a 15-20 percent drivetrain loss in power depending on transmission, drive type and other variables. On a big truck with beefed up components for hardcore off-roading, you’d expect the Ram TRX to have a bigger drivetrain loss than say, a manual Mazda MX-5 Miata. But the  Hellcat pickup actually turned up a pretty respectable drive train loss of about 17 percent. 

Check out the video below to hear the Hellcat motor scream on the dyno:

Hennessey, meanwhile, aims to boost the Ram 1500 TRX’s numbers well beyond the original figure. Called the Hennessey Mammoth 1000, the Texas firm’s TRX package boosts output to an insane 1,012 and 969 lb-ft of torque. This will be possible thanks to an upgraded supercharger, new engine tune, and a high flow exhaust with stainless-steel headers. Outside of the power, Hennessey’s Ram TRX Mammoth package will bring an Off-Road Stage 1 package. It features a 2.5-inch suspension lift and leveling kit, 20-inch HPE wheels, as well as a new bull bar and LED light bar setup. 

Hennessey is estimating 0-60 in 3.2 seconds. In a truck weighing north of 6,000 lbs, this is staggering. But we’ve only seen a rendering of the Mammoth thus far, so we’ll have to wait and see if the final product can verify these claims.
