Kyle from Dark Iron Diesel flew his blown up 12 valve Cummins out to Power Driven Diesel so the crew could rebuild it from the ground up, and this episode follows the build while the guys dig into what actually separates a fast truck from a truck that just sounds fast.
Kyle's 12 valve made 650 horsepower before a nitrous mishap put a freeze plug through the block and warped the head. Instead of a simple repair, Todd, Will, and Myer turn it into a full stroker build, taking the 5.9 out to a 6.1 liter on a 6.7 Cummins crank that Power Driven now manufactures in house. They cover custom Wagler rods, ceramic coated pistons, a reconditioned head, a Colt Stage 4 cam, and an Aggressor 60/65 over 98 compound turbo setup aimed at 1100 to 1200 horsepower.
We filmed the full teardown, machine work, and stroker crank install start to finish, so keep an eye out for the build video covering every step of this engine in detail.
The crew also compares Myer's 1300 horsepower race truck against Kyle's Lamborghini Huracan, which he had on hand from a cross country supercar rally, breaking down 0 to 150 times and why horsepower alone does not tell the story without weight and traction factored in.
Kyle also talks about walking away from a potash mine job to do YouTube full time and his approach to dyno testing.
