Diesel Power Challenge 2016 - Travis Koller

’15 Ford F-250, 6.7L Power Stroke

We’re pretty sure the entire Diesel Power Challenge Class of 2016 shares Travis Koller’s feeling of being a “winner,” simply because like Travis and his ’15 Ford F-250, each competitor represents one of the 10 people and their trucks that were chosen to compete in the event. “I bought this truck brand-new off the dealer’s lot and started playing with it as soon as I got home,” Travis says. “Making it into Diesel Power Challenge has been a goal since the first time I saw a video of the event. Just being nominated and now getting here is a win for me.”
While the daily driven rig is often used for drag race and sled pull competition (installing Add-A-Leaf helper springs is actually the result of having to repair the rearend after it twisted while pulling), Travis hooks it up to and tows heavy machinery on a regular basis. Furthermore, it does the job with only conservative—by hard-core, diesel-guy standards—upgrades done to its 6.7L Power Stroke engine (the lone 6.7L Ford in the competition).

“I had already added a Midwest Diesel & Auto 65.5mm StreetMaxR turbocharger (modified stock VGT),” says Travis. “But, for the Challenge, I installed a custom cold-air intake setup by Absolute Performance and Maryland Performance Diesel intercooler tubing. I also have a few different Spartan Diesel Technologies ECU calibrations I can select for each individual segment, as well as for the weather and track conditions.”
It will definitely be interesting to see how well the combination of a relatively simple drivetrain package, the newest truck entered in DPC, and Travis’ driving skills will answer the demands of the various events in the competition.

You’re looking at the newest (and least modified) engine in the entire Diesel Power Challenge 2016 lineup. While the 6.7L Power Stroke in Travis Koller’s ’15 Ford F-250 is upgraded with only a modest assortment of bolt-ons (compared to powerplants in other DPC competitors’ rigs), we’re not underestimating its capability in any way. This engine might surprise a few folks in Denver.

While traction bars are the norm for most street-strip pickup trucks, the bars helping Travis’ rig hook up are pieces Travis designed and bolted to the truck’s chassis (they’re usually welded on). Urethane bushings, as opposed to Heim joint rod ends, are unique pieces that help keep the ride smooth and quiet.

We dig the personalization of the truck’s front four-link suspension system, which was fabricated by Duane Burkholder. Koller’s setup definitely is “killer.”

Travis’ F-250 is super clean and it “sits” perfectly, thanks to a great balance of front and rear leveling and lifting hardware, 18x10 Moto Metal MO962 wheels, and 35x12.50R18 tires at all four corners.
