Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"

Chrysler called out over lackluster Ram Runner by racer who helped develop it

Fans of off-roading and desert blasting might recall that Chrysler offers an aftermarket conversion that can turn a Ram 1500 into a road-legal desert racer, called the Ram Runner. The kit, sold through Mopar, includes some significant suspension upgrades, body tweaks and a brawnier cat-back exhaust for the truck's 5.7-liter V8.
Considering all of this, comparisons with the almighty Ford F-150 SVT Raptor are common. Among the off-road community, that makes these two a sort of Chevrolet Camaro and Ford Mustang for people that prefer driving on dirt. In the Race-Dezert forum, the discussion as to which truck was better was proceeding as normal - Ram fans said their piece and Ford fans said theirs. Then, a man named Kent Kroeker offered up his two cents.
See, Kroeker is a Baja racer, and the man that helped develop the Ram Runner. Despite his association with the truck, though, he had some less than kind words for Chrysler and the Ram Runner.

Motor Trend pits Subaru WRX vs. Ford Focus ST

The Ford Focus ST has enjoyed a relatively calm, if brief, reign in the world of hot hatches. With nothing else in the class (in the States, at least) but the aging Mazdaspeed3 and Subaru Impreza WRX and the slow-selling Volkswagen Golf R, the Blue Oval's 252-horsepower five door has been the go-to vehicle for those that don't need the high-octane lunacy (and expense) of the rally bred Subaru Impreza WRX STI and Mitsubishi Lancer Evolution X.
Now, though, as the new Subaru WRX (it's not an Impreza anymore, though, neither is it a hatchback...) starts to arrive at dealers, the Focus ST appears to be under threat for the first time. Naturally, Motor Trend is here to figure out which one is the best, with another one of its Head 2 Head videos. Host Jonny Lieberman puts both cars through their paces, going above and beyond, quite literally, at the very end of the video.
