This episode of the Power Driven Podcast features Will, Todd, and Meyer sitting down with Josh after his record setting dyno hit. They cover the whole story from his three thousand horsepower number at UCC to the follow up run in Richfield where he picked up uncorrected power and set a new benchmark. They also dig into why corrected versus uncorrected numbers always stir debate and how altitude, air density, and weather factor into the Dyno sheet.
Josh explains what it is really like strapping in for a pull at this level, running full safety gear including a fire suit, helmet, suppression system, driveshaft loops, scatter shields, and even a plate carrier. The team also laughs about viral comments, correction factors, and the reality that after a record hit, the truck still has to drive onto the trailer.
On the hardware side, the build is based on a cast Cummins block with a deck plate, forged internals, upgraded pushrods, and ported headwork that really shined on the exhaust side. A Steed manifold and smart waste gate setup helped improve airflow, while a refreshed transmission with a tighter converter and updated clutch packs put more of the power to the rollers. The combination came together cleanly, making less boost and drive pressure than before, but more horsepower on the sheet.
The episode also covers the Dyno process itself, how the rollers measure torque and rpm, how correction factors are applied, and why a one second pull can carry so much weight in the diesel performance world. For a full second, Josh’s truck held over three thousand horsepower and climbed through the fours, leaving the shop silent and then cheering.
This is diesel performance at its wildest, record breaking Dyno numbers, Cummins power pushed to the limit, and shop talk that blends serious tech with real world racing stories.
