The proverbial numbers—the very unofficial, yet perceived-as-fact statistics—tell us that when it comes to brand loyalty and overall fan base for diesel pickups, Fords are typically on the shorter end of the respect spectrum.
However, despite the hate by others, there are still plenty of Ford loyalists who believe in the Blue Oval’s oil burners and feel the F-Series rigs are plenty capable of holding their own against the mighty Dodge/Ram trucks and even the GMs that compete in Diesel Power Challenge. For 2015, the Ford lovers apparently have extreme amounts of confidence in the ’06 F-250—another 6.0L-powered entry—owned by Jaran Holder, which they voted into DPC’s Ford group by a landslide margin.

At first blush, you immediately think “underdog,” when looking at the former work truck. It’s the only single-cab entered, and where other competitors’ went the extra mile to ensure their pickups look like mean machines (and, of course, run well), Jaran says his focus was on getting everything out of the engine he built (and validating the mettle of 6.0Ls everywhere), rather than giving the crowd something pretty to look at.
“I’ve always had a love for the 6.0L Power Stroke,” says Jaran. “One of my father’s favorite quotes, from Robert Frost’s poem, The Road Not Taken, reads: ‘I took the one less traveled by, and that has made all the difference.’ I used that as inspiration for my build because not many people have pushed the 6.0L to its limits like they do other diesel engines. I plan to continue to push my truck’s combination until there is nothing more to gain.” With Jaran’s outlook for the engine’s performance to reach the 1,000hp zone, we’re anxious to see if taking that road works out for him at DPC.

The aforementioned combination features fly-cut Mahle pistons, R&R Racing connecting rods, and Colt Cams’ Stage 3 billet camshaft. Jaran ported and O-ringed the cylinder heads himself and added high-rev valvesprings and chromoly pushrods, before securing them to the block with ARP studs.
Once a single-turbocharged engine, Jaran’s 6.0L now sports a “specifically for DPC” compound setup that includes Jaran’s self-ported intake manifold and BorgWarner’s S467 and S483 ’chargers. A JGS 50mm wastegate and Mishimoto intercooler round out the induction package. “I added the compounds just one week before heading to Denver,” Jaran tells us.

Basic (by today’s standards) best describes the F-250’s fuel system. A set of Warren Diesel’s 430cc, 150-percent-over hybrid injectors are fed by a pair of HPOPs and a FASS 220-gph lift pump. That’s it.
While it’s not an outright eyesore, Jaran’s F-250 truly is no-frills; a rig that Seattle Seahawks running back Marshawn Lynch would say is strictly “’bout that action, boss,” both inside and out. With its very unconventional 1-inch lowered stance (which disguises the fact that the truck is actually four-wheel-drive), we forecast the truck will be a rough customer in the trailer-towing segment and in drag racing competition, and we kind of wish DPC events included a formal autocross for the big machines, because Jaran’s looks like a sports truck that will out-handle all of them.
