One spec turbo, instant green starts, and a purse swelling toward one hundred grand turned this class into the wildest storyline in diesel drag racing.

This episode of the Power Driven Podcast is hosted by Will and jumps straight into the future of diesel motorsports with Josh and Myers in the room. The crew uses the 72 Fast class that runs alongside UCC in Indianapolis as the case study for where the sport is heading and why it matters to anyone who cares about diesel performance and the community that builds, tows, tests, and races these trucks.

They lay out the rules that make this thing so fierce. Every entry runs a VS Racing seventy two eighty T4 turbo and must weigh a strict six thousand pounds with no tolerance. It is fuel only, so no nitrous, no injectables, and no water to air intercoolers except where a factory six seven Power Stroke came with one. Factory pumps are required, a factory ECM is mandatory even if you swap brands, and there is no trans brake. There is a parc ferme style impound between rounds, no test passes in the days before the event, and an instant green start on race day. The entry options even included a package with the turbo, the purse began at fifty thousand, contingencies piled on, and the total payout grew toward one hundred thousand as the entry list capped at one hundred thirty five.

From there it gets technical in all the right ways. The guys explain why common rail tuning windows and cylinder head airflow are a real edge over a twelve valve, how port velocity and reversion affect turbo efficiency, and why a P pump setup benefits from a larger turbine to deal with heat and drive pressure. Expect everything from eight or nine hundred horsepower to well past a thousand, and on an eighth mile you could see anything from six eighties to possible high fives depending on weight, power, and the leave. With foot brake only and an instant green tree, reaction time and a clean launch can beat raw power, which is exactly why this format pulls in racers from street truck roots to serious shop builds.

Culture and logistics get their due as well. Burnout pits are drawing bigger crowds because fans can stand close and feel the noise and smoke, which makes them a real part of the show. There is talk of bringing an air limited, fuel only class out West, maybe pairing it with dirt drags or a street weight sled pull so the barrier to entry stays low. The no time format keeps scoreboards dark, but the tower still sees times and track officials have the final say, a reminder that safety, licenses, and sportsmanship still matter when serious money is on the line. Contingency bounties add even more spice, including brand versus brand bonuses when one platform sends another home.

If you live for diesel performance, Power Driven Diesel tech, Cummins talk, VP44 history, dyno testing, turbo upgrades, drag racing, and truck builds, this conversation is packed with shop floor reality and race day strategy. Long tail topics woven throughout include 72 Fast class rules at UCC, VS Racing seventy two eighty spec turbo details, six thousand pound minimum weight, factory ECM only with no trans brake, instant green fuel only diesel drag racing, no test pass rule with impound, and eighth mile strategy on a budget.
