There are very few people in this world that would look at a Ram 1500 TRX and think that it wasn’t excessive. Thanks to its 6.2L supercharged V8 engine, the off-road pickup pumps out 702 horsepower and 650 lb-ft of torque straight from the factory. And while this is enough shove to make it the fastest, quickest, and most powerful truck on sale today, it still wasn’t enough for John Hennessey. This Texas tuning fanatic has long been known for his high-horsepower antics by way of his company, Hennessey Performance Engineering. These madmen down in Texas have designed their own version of the Ram called the Hennessey Mammoth 900, which is essentially a TRX turned up to ten. In order to prove just how potent the modified pickup is, Hennessey squared the truck up against a Chevrolet Camaro ZL1 1LE for an old school drag race.

The Hennessey Mammoth 900

The Hennessey Mammoth 900 starts life as a standard Ram 1500 TRX, before the team in Texas makes a few key adjustments to the powertrain. HPE’s package includes upgrades like some supercharger accessories, high pressure fuel injectors, and their proprietary tune. This brings output up to 912 horsepower and 873 lb-ft of torque at the crank. When stuck on the shop’s dyno, they found the truck actually puts 728 horsepower and 679 lb-ft of torque to the wheels. That’s impressive stuff, regardless of the fact we’re talking about a half-ton pickup. Importantly for the race against the Camaro ZL1, all of that power gets sent to both axles.

Chevrolet Camaro ZL1 1LE

The Chevrolet Camaro ZL1 1LE is an incredibly fast muscle car. Not as outright powerful as the Shelby GT500 or the Dodge Hellcat models, the ZL1 makes up for that with a lower curb weight and a responsive chassis. That isn’t to say that the Chevy is “underpowered” by any means however. Thanks to its 6.2L supercharged LT4 V8 engine, the Camaro ZL1 1LE pumps out 650 horsepower and 650 lb-ft of torque. That may be a lot less than the truck, but the Camaro tips the scales at 3,944 pounds. That is super lightweight compared to the TRX, which tips the scales at 6,396 pounds.

The Race

Unfortunately for muscle car fans everywhere, the weight difference wasn’t nearly enough to help the Camaro ZL1 1LE edge out the Hennessey Mammoth 900. All of that power running through four wheels was just far too much for the ZL1 to handle. The truck dominated the first race, while the second pass was a bit closer. Regardless, the Hennessey Mammoth 900 pulled incredibly hard right out of the gate. The Camaro on the other hand struggled quite a bit to get out of the hole. Once traction was found, the race was essentially over for the Chevrolet.

As the Hennessey Performance Engineering employee notes in the video clip, it is best not to underestimate a truck in Texas. Muscle car fans need not fret however, as HPE built an insane a Camaro with more than double the power of this stock machine. They just won’t be building anymore, however.
