Putting a Cummins diesel engine into vehicles they never came in remains a popular swap. However, YouTuber Westen Champlin took it to another level with his recently acquired 5.9-liter 12-valve Cummins-powered Ford Ranger. Built on a heavy-duty 3/4-ton chassis, this compact truck faced a barrage of extreme tests in Champlin’s latest video, showcasing both impressive capability and predictable chaos.

Champlin found the pre-swapped Ranger via Facebook Marketplace and immediately embraced its rough-and-ready nature. He declared, “this is my style, it’s junk and I love it.” After confirming its burnout potential (which violently removed the tonneau cover), he subjected it to a tug-of-war against his own massive big-block powered Ranger riding on 49-inch tires.

After sorting out how to engage the four-wheel drive, the Cummins Ford Ranger easily dragged the monster truck. The real spectacle involved towing tests using the truck’s gooseneck hitch. First, it easily pulled a large trailer loaded with two other Ford Rangers, weighing over 20,000 pounds. Champlin noted, “it pulled it perfectly; it didn’t struggle at all.” Seeking a bigger challenge, he then chained his colossal “Battle Tank Ford Ranger” (estimated at over 30,000 pounds) behind the already loaded trailer, putting over 50,000 pounds behind the Cummins Ford Ranger.

He admitted “might be a stupid idea” with only a “10-percent chance” of success. Champlin was shocked when the truck actually moved the entire load and shouted, “holy… I cannot believe it did that that is crazy!”

Bigger Turbo, More Power, More Chaos

Never one to leave things alone, Champlin’s team then painted the truck yellow, swapped on a larger turbo reportedly taken from his old “Smokestang” project, installed a hood stack, and boldly wired the wastegate shut for maximum boost.

Testing the truck’s quarter-mile performance in a field resulted in a respectable 14.58-second pass. However, the excessive boost proved too much for the intake plumbing, blowing an intercooler boot off spectacularly. “It rips more than that boot… wants them to rip,” Champlin concluded after the failure.

Champlin stated these initial tests established a baseline before planned modifications to “triple the horsepower.” This Cummins-swapped Ranger, capable of towing extreme weight and laying down impressive burnouts (between breaking parts), certainly pushes boundaries.

What do you think of Westen Champlin‘s 1,000 horsepower build? Is it impressively capable, certifiably crazy, or maybe both? One thing is for sure. It’s one of the wildest Ranger builds showcased online.
