Diesel Power Challenge 2018 Presented by XDP is in full swing, with Day 3 bringing what arguably is the most popular competitive segment of the six grueling stages that comprise the annual event: The worshipped-by-all chassis-dyno showdown to determine which player’s rig is superior when it comes to making rear-wheel horsepower and torque.
One day after the Mustang dyno at ATS Diesel Performance proved to be more challenging than some competitors might have anticipated (four drivers failed to complete a grueling fuel-consumption drive), our nine teams returned to ATS with a ton of confidence—the trash talk among them confirms this--and ready to take on DPC’s marquee performance test.
Making four-digit horsepower in the Diesel Power Challenge dyno test is the optimistic performance goal that most competitors have each year. And, while their trucks certainly may be capable of making that type of big steam on their respective “home dynos,” such variables as Denver-area’s high elevation (5,800 feet above sea level at ATS) and the fact our competition uses data that is not corrected for that altitude, often leave participants scratching their heads in disbelief, questioning the dyno’s accuracy, or trying to conjure up some plausible excuse for performance that falls (sometimes far) below what they expected—and in some cases, boasted about. Basically, where a truck might post 1,200 (corrected) horsepower on a competitor’s regularly used dyno (that typically is in lower altitude), its uncorrected figure on the ATS Mustang unit will probably be a tick below 1,000hp.

Understandably, the difference is dramatic and can be a bit humbling (one crew member/tuner confessed that his pride was a little hurt by his truck’s performance on the pump). But, when a team makes all the right moves when preparing for DPC Day—specifically by focusing on calibrating the ECM with an optimal tune for making power in thin air, and adding a lot of nitrous oxide for much-needed additional atmosphere—boasts of big power can be backed up.
Diesel Power Challenge alum, Dmitri Millard, proved this by tuning Kodi Koch’s (pronounced as “Cook”) ’01 Chevrolet Silverado 2500HD, and coaching Kodi (it was his first time ever driving on a dyno) to a dominant win in the dyno segment (1,400.4hp/2,417.7 lb-ft). Uncorrected horsepower and torque values are combined and the overall total is used in scoring this segment.

There were smiles (especially in the Koch camp), and there were frowns. But, all in all, the Diesel Power Challenge 2018 dyno segment was an awesome display of diesel-engine performance. The following photos are highlights from Day 3. Today, the DPC 2018 entourage travels to Bandimere Speedway in Morrison, Colorado, for on-track action in the Eighth-Mile Trailer Tow, Quarter-Mile Drag Race, and Trailer-Tow Cone Course segments. See all the action though our live feed (presented by American Force Wheels), on the Diesel Power Magazine Facebook page, or right here in trucktrend.com.
