• Hennessey Wants To Give The Ram TRX and Durango SRT A Hellephant Swap

Because 6.2-liter V-8s making 700+ horsepower is for amateurs, right?

When you hear about a Hennessey build, you know it’s going to be fast and powerful. And it’s not just supercars, either, as the company has injected even SUVs and trucks with doses of steroids in the past and continues to do so. Recently, the company uploaded a video on YouTube wherein John Hennessey talks about his plan to plonk Mopar’s Hellephant engine into the Ram 1500 TRX and the Dodge Durango SRT.

We Could Be Looking At Two 1,200+ Horsepower Vehicles Here

In the video, John Hennessey talks about pairing the Hellephant engine with the Ram 1500 TRX and the Durango SRT. The Hellephant engine is a homage to the 426 HEMI V-8 from the past. Mopar sells the Hellephant as a crate engine, which it unveiled at the 2018 SEMA Show. It displaces at seven liters and comes with a 3.0-liter supercharged that made 15 pounds of boost. The result of this was 1,000 horses and 950 pound-feet of torque.

The aftermarket company has already tried this in the TRX when it built a 6x6 version of the truck called the Mammoth. But, coming from Hennessey, no stick figures are even enough. So, they tuned it up to produce 1,200 horses, thus making it one of the most powerful trucks ever. The company has even tuned-up the standard 6.2-liter supercharged V-8 Hellcat engine and offers the TRX with it. It makes 310 horses and 319 pound-feet of twist more than the stock truck, which brings the power output to 1,012 ponies and 969 pound-feet of torque.

John even mentioned Hennessey’s got about 60 TRXs in total, so it seems like a popular choice for the Hellephant build in the four-wheel-drive avatar. For now, the company has got two Hellephant crate motors with it, which could mean both, the TRX and the Durango, getting one engine each. We could see these builds make more than 1,200 horses and perhaps, over 1,000 pound-feet of torque too.

This video was the first episode of a new ‘Hellephant Madness’ series, so we could see the crate engines being plonked into the vehicles in the upcoming videos.
