DPC 2017/Day 3: Dyno Performance
Diesel Power Challenge 2017: Day 3
As Diesel Power Challenge events go, the demonstration of horsepower and torque on the chassis dyno arguably is the most feverishly anticipated segment of the competition, and it has been so for more than a decade.
In what seems like just a few short hours after concluding Day 2 activity on the pump (for the uninitiated, “the pump” is an old-school, but still-cool term used for a dyno) at ATS Diesel Performance (for the fuel-consumption/drivability test), nine competitors returned to the Arvada, Colorado-based diesel center to have their trucks strapped down on the rollers once again. This time, however, the second go-‘round was strictly for the purpose of seeing exactly how they all match up performance wise, in Day 3 of Diesel Power Challenge Presented by XDP.
That’s right; the all-hallowed dyno clash was the only competitive segment on the agenda. However, the landmark happening that really made the air electric on DPC 2017’s third day, was the launch of LIVE coverage of the Challenge (made possible by Fleece Performance Engineering), via video streamed on www.trucktrend.com and the Diesel Power Magazine Facebook page, as well as across countless other social media pages.
While there was an assumed expectation by all crews and staff for Charlie Keeter’s ’04 Ford F-250 to be one of the heavier-hitting, if not the most dominant rig in the dyno session, the 2016 DPC champ’s 1,099.9 hp and 1,722.3 lb-ft of torque (2,822.2 combined) landed him in Fourth place. The position was a surprise to many folks in attendance (and also viewing the feed), but Charlie took not reaching the podium in great stride, and we’re sure he immediately began plotting next steps for achieving high scores in the remaining segments.
The dyno competition definitely was filled with surprises. McCoy Black’s ’95 Dodge Ram 2500—a 5.9L Cummins-powered truck that was completed just three weeks before the Challenge—leapt out of the event’s scoring basement with a phenomenal 1,255.8 hp, 2,131.8 lb-ft (3,387.6) run. On the previous night, McCoy left the dyno with concerns about a superheated engine, and carrying a last-place DNF score for the fuel-consumption test.
Finishing closely behind McCoy was Tim Jahn, who’s ’08 Ford F-250’s 6.4L Power Stroke engine blasted out 1,315.7 hp and 1,999.4 lb-ft (3,315.1). Patrick Whitcomb’s ’08 F-450 dualie rounded out the Top-3 dyno scores for the day, posting very solid 1,147.5 hp and 1,860.3 lb-ft (3,007.8).
All in all, everything ran smoothly and without any carnage (with the exception of a leaking rear transmission seal in McCoy’s rig, which the team repaired at ATS Diesel Performance. No radical breakage is a bit atypical for DPC’s power-and-torque test, but the issue-free dyno pulls helps ensure that nine trucks will be ready to go for on-track events at Bandimere Speedway in Morrison, Colorado, on Day 4 of Diesel Power Challenge 2017 Presented by XDP.
