Heavy-duty machinery semi truck engines reign supreme, but one colossal creation towers above the rest: the legendary Thor 24, boasting a monstrous size that dwarfs all competition.
While heavy-duty pickup trucks may impress with their V8 engines, they pale in comparison to the sheer magnitude of the biggest and best semi trucks. Brands like Peterbilt and Kenworth have earned global acclaim for their massive engines, but it takes a true visionary with deep pockets to push the boundaries of engineering. Enter Mike Harrah, the mastermind behind the awe-inspiring Thor 24.
To claim the title of the largest displacement semi truck engine, Mike embarked on an ambitious project, combining two Detroit Diesel V12 engines into a jaw-dropping creation. But he didn’t stop there seeking to Thor’s power to unparalleled heights, he outfitted the 27.9-liter V24 engine with an astonishing 12 superchargers and a generous dose of nitrous oxide. This boost in power catapulted Thor 24 to an astounding 3,974 horsepower, making it a force to be reckoned with on the road.
Built upon a 1984 Peterbilt 359 Ultra Custom TT Crew Cab, Thor 24 is a sight to behold, stretching a colossal 44 feet in length and tipping the scales at a staggering 32,000 pounds. Its custom leather interior, hot rod-inspired dash, and state-of-the-art entertainment system reflect Mike’s attention to detail and commitment to excellence. And with four 12-foot parachutes to bring it to a halt, Thor 24 commands attention wherever it goes.
In 2019, Thor 24 made waves at auction, fetching a staggering $13.2 million to its unparalleled craftsmanship and engineering prowess. While other semi truck engines may boast impressive horsepower and displacement, none can rival the sheer magnitude and innovation of Thor 24.
From the Volvo FH16 to the Detroit Diesel DD16, these engines may be formidable in their own right, but they pale in comparison to the modified marvel that is Thor 24. With 12 superchargers, 24 cylinders, and a touch of NOS, Thor 24 reigns supreme as the undisputed titan of semi truck engines.
