The 2021 Ram 1500 TRX offers a manufacturing facility-quoted 702 hp and 650 lb-ft of torque, but which is as calculated at the crank, not the wheels. Hennessey Efficiency Engineering attempted to evaluate how significantly electric power the TRX makes at the wheels by strapping a single to a dyno, but only ran figures for the rear wheels.
The dyno examination showed 538 hp and 570 lb-ft of torque at the rear wheels. That represents all-around 17% driveline decline, which is just not unusal for a pickup truck. Hennessey formerly recorded 20% driveline reduction at the rear wheels when it examined a 2019 Ford F-150 Raptor.
The TRX is comprehensive-time four-wheel drive, so you could be asking yourself how Hennessey received dyno benefits for the rear wheels only. Firm founder John Hennessey instructed Motor Authority that four-wheel generate was disabled by disconnecting the front driveshaft.
2021 Hennessey Mammoth 1000 1500 TRX
Though the TRX was made for off-roading, the quantity of power produced by its 6.2-liter supercharged Hellcat V-8 will make this truck really speedy on pavement. Ram states it will do -60 mph in 4.5 seconds.
Inevitably, that was not sufficient for Hennessey. The company has produced more highly effective versions of each individual Hellcat-driven car, and it’s executing the exact with the TRX. Dubbed the Mammoth 1000, Hennessey promises its consider on the TRX will boast 1,000 hp, will do -60 mph in 3.2 seconds, and operate the quarter mile in 11.4 seconds.
To achieve people numbers, Hennessey options to equip the Mammoth 1000 with an upgraded supercharger, pulley, and air intake, stainless-metal headers, substantial-stream exhaust piping (retaining the catalytic converter), and new engine mapping. The price tag for the finish truck is $135,350, and Hennessey only designs to establish 200 this calendar year.
