The General Motors Of Diesel Power Challenge 2011

Power. It’s what we all seek as diesel owners. Our compression-ignition, direct- injection engines give us every advantage over the common gasoline-vehicle drivers in the world. Our diesels give us the torque to tow, the strength to haul, the efficiency to get 20 mpg, and the speed to blow the doors off anything else on the road. That’s the Diesel Power way.
In the next 38 pages, you’ll be exposed to 10 daily-driven diesel pickups that have outrun, outgun, and outdone every other street-legal pickup on the planet. We’ve invited all of them to come together to battle in our seven tests of power. We call this event the Diesel Power Challenge, and this year we’ve invited this elite group of Dodge, Ford, and GM owners to gather in Denver, Colorado, for three days of torque, torture, and triumph.
In this month’s issue, we’ll give you a look at the components and drivers that make these machines so potent, but you’ll want to be sure to check back next month to see all the action from the dyno, dragstrip, sled pull, and 160-mile fuel economy drive.

Newly Tolf is an avid drag racer, and his strategy coming into Diesel Power Challenge showed that. Thanks to the influence of an NHRA-sanctioned dragstrip located in his hometown of Las Vegas, Nevada, Newly showed up at the event with a gutted interior and only one seat. His strategy was to dominate the asphalt events like the drag race and the trailer tow and sacrifice some distance in the sled pull. His choice of Nitto 420S tires meant traction would hopefully not be an issue while running down the quarter-mile. Look for Newly’s Dodge to be the strongest on the dragstrip, and with high 10s already under its belt, this lightweight truck could very well jump off to an early lead.

Hailing from ignacio, colorado, Fidel Valasquez comes ready to make a serious dent in this year’s competition. A built bottom end will ensure the Chevy’s Duramax engine can handle all the events with ease, while compound turbos (an S366 over an S483), a two-stage NX-D 4000 nitrous system, and Snow Performance water-methanol kit helps the engine make an owner-estimated 800 hp and 1,200 lb-ft of torque.
Fidel also chose a set of Nitto Dune Grapplers for traction, which have proven to be a very good tire for Diesel Power Challenge. When the competition starts, this bad blue Chevy is going to be a force to be reckoned with.

Owen Horst could be considered a front-runner for the win. With dyno and drag racing expertise, Owen also has experience in the broken parts department, after scattering his engine a few days before last year’s challenge while it was making more than 1,900 lb-ft of torque.
In the past, he’s also made the final day of sled pulls in the prestigious Scheid Diesel Extravaganza, so it’s clear that Owen has experience on his side in all events. This year Owen’s truck is even stronger, as the GMC is rumored to make four-digit power without the three-stage nitrous system. Look for Owen and his truck to be a major player in the sled pull and dyno competitions.

Last year’s winner, Dmitri Millard, is back to defend his title—with more horsepower than ever. After last year’s challenge, Dmitri went on a dyno rampage, putting down 1,437 hp, 1,585 hp, and 1,708 hp on various chassis dynamometers throughout the country. This Chevy isn’t a one-trick pony, however, as Dmitri also clicked off numerous 10-second passes, at more than 130 mph. Huge Garrett turbochargers (the GT55 is a whopping 106 mm in size) along with multiple stages of nitrous are what make this truck so dangerous to the competition.
With low 10s under his belt in the quarter-mile and a record-breaking trailer tow last year, look for this unreal Duramax-powered Chevrolet to dominate the dyno, trailer tow, and dragstrip events.
