The truck could end up making as much as 1,200 hp.
The Ram 1500 TRX is a seriously disappointing truck. Its weedy 6.2-liter supercharged V8 Hellcat engine can only manage 702 horsepower and 650 lb-ft of torque, and those figures amount to a leisurely 4.5-second run to 60 mph. Even worse, the quarter-mile takes a tardy 12.9 seconds.
Of course, we've just fed you a bunch of utter garbage. Those are phenomenal numbers for any car, let alone a full-size truck. In fact, the only people who would dare to consider the deranged TRX slow or in need of more power are the guys at Hennessey, but they've just announced a plan to remedy this.
In a new video, John Hennessey himself revealed that they plan to shoehorn Mopar's Hellephant crate engine into a new TRX. In case you forgot, this 426-cubic-inch, 7.0-liter supercharged V8 powerplant produces a staggering 1,000 hp. Although Hennessey has already squeezed that amount of power out of a TRX, the Hellephant engine is capable of producing more than 1,200 hp. That would represent an increase in power of over 70 percent over the already massively capable stock TRX truck. A bonus is the fabulous sound that the Hellephant engine unleashes.
John Hennessey then kept the good news rolling by showing off a new Hellcat-powered Durango, which he says would also be a perfect recipient for a Hellephant engine swap. He didn't confirm which vehicle would get the engine swap first but did suggest that there'd be a video series chronicling the process. Remember, too, that the stock Durango SRT Hellcat is even quicker than the TRX, needing just 3.5 seconds to reach 60 mph. How close could this family SUV and the TRX get to the magic three-second mark if powered by the Hellephant engine? Hennessey seems determined to answer that question and we're not complaining.
