A few months ago we shared the wild 2021 Dodge Ram TRX being built by Hennessey Performance. They replaced the factory supercharged 6.2 L Hellcat V8 with a supercharged 426 ci (7.0 L) Hellephant V8. The swap gifted the truck with 865 horsepower and 912 lb-ft of torque to the rear wheels on 93 octane fuel (was too big for 4WD dyno). With the swap complete and dyno tuned, the truck’s next step was Pennzoil Proving Ground for a test drive.

To just the rear? Was it not a 4×4? I thought all the TRXs were. 🤔
You are correct. It is 4WD. We forgot to include the truck was too big to dyno 4WD. So they only dyno tuned to RWD. Article is update.
