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!"

2015 Dodge Viper getting small increase in power

The Viper is used to being the most powerful car in the Dodge and SRT stables, but the arrival of the 2015 Dodge Challenger SRT Hellcat means that's no longer the case. The serpentine supercar is, however, reportedly getting a small boost in output for 2015, amounting to all of five horsepower.
The increase was uncovered by Road & Track courtesy of the SAE J1349 certification process to which Detroit's Big Three automakers submit themselves and which reports the Viper's output at 645 hp instead of the 640 it was rated at until now. There are a hundred factors that could have contributed to the relatively mild boost in output (best guess? nothing at all changed...), but we doubt anyone's going to complain about some extra horses under the hood.
The five-horsepower boost brings the Viper that much closer to the 650-hp Chevy Corvette Z06, not to mention the 707-hp Hellcat, but the Viper's impressive power-to-weight ratio ought to mean it'll have little problem keeping up in a straight line - which is just one of the reasons why Chrysler won't shoe-horn the Hellcat into the Viper: as R&T points out, the supercharged engine is too heavy and the blower makes it too tall to fit in the Viper's engine bay.

Legacy Classic Power Wagon First Drive

Shortly before the US entered World War II, Dodge supplied the military with a line of pickups internally codenamed WC, those letters designating the year 1941 and the half-ton payload rating. From 1941 to 1945 Dodge built more than a quarter million of them, and even though "WC" came to refer to the Weapons Carrier body style, the WC range served in 38 different configurations from pickup trucks to ambulances to six-wheeled personnel and weapons haulers. The story is that soldiers returning from active duty badgered Dodge for a civilian version of that indefatigable warhorse, so Dodge responded with the Power Wagon in 1946. Even for those no-nonsense times the truck was so austere that the first three names Dodge gave it were "Farm Utility Truck," "WDX General Purpose Truck," and "General Purpose, One Ton Truck." "Power Wagon" was the fourth choice, not finalized until just before it went on sale. Nothing like today's Power Wagon, the original could be seen as either a glorified tractor or a slightly less uncouth military vehicle – hell-for-leather meant going 50 miles per hour. But it would go nearly anywhere. The civilian version was still built like it had to survive, well, a world war; power take-offs (PTOs) ran all manner of ancillaries; multiplicative gear ratios helped it produce enough torque to make an earthquake envious. Said to be the first civilian 4x4 truck made in America, any organization that needed a simple, sturdy mechanized draught animal knew it needed a Power Wagon.

The Jackson Hole, WY, restorer retains every ounce of the Power Wagon's orchard-work aptitude, decorated with present-day amenities and the best components. Each job starts with having to find a usable donor. The city of Breckenridge, CO, bought the red truck in our gallery in 1947 and used it as a snowplow for the next 30 years. In 1977 a log-home builder bought it from the city and used it for another decade as a company hauler. That's the kind of grueling longevity that lets Ram put a five-figure premium on the 2500 Power Wagon pickup it sells today. Legacy Classics founder Winslow S.
