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!"

1979 Dodge Li'l Red Express in Generation Gap showdown with 1933 Ford Pickup

Auto enthusiasts love a good debate, whether it's Mustang versus Camaro or Ferrari against Lamborghini. But how about a battle between two very different vintages of classic pickup trucks? In this case, the fight is between a 1979 Dodge Li'l Red Express and a 1933 Ford Model 46 truck with a flathead V8.
The shootout comes courtesy of the internet series Generation Gap, and its concept is super-simple. One guy prefers classics, and the other likes newer rides. They choose a category, pick two vehicles and put them head to head. In this case, neither is exactly modern, though. The Ford is more than old enough to receive Social Security checks, and the Dodge is hardly a young whippersnapper.
Other than both being pickups, these two models were made to serve very different functions. The Li'l Red Express was basically the progenitor of today's muscle trucks, with a big V8 that made it one of the quickest new models in its day (admittedly, 1979 was a rough time for automotive performance). On the other hand, the '33 Ford was just meant to work, with little pretense for anything else. One of the hosts describes it as "the simplest, most difficult" vehicle he's driven because of the tricky double clutchwork necessary to shift gears. Scroll down to watch the video and try to decide which of these two American classics you would rather have in your garage.

Chrysler recalls 350k vehicles over ignition switches

Chrysler has announced a recall covering 349,442 vehicles due to ignition switches that can either become stuck or move without warning. All of the affected vehicles are from the 2008 model year, and were built before May 12, 2008.
The automaker has learned that ignition keys on some vehicles "may not fully return to the 'ON' position after rotation to the 'START' position during engine-startup," the company said in a statement. Additionally, "an ignition key may not fully return to the 'ON' position after rotation to the 'START' position and may inadvertently move through the 'ON' position to 'ACCESSORY' or 'OFF.'"
Chrysler says it is unaware of any related injuries, and notes that while reduced braking, engine or steering power is possible in such instances, the airbags are not affected. The later stands in contrast to General Motors' recent rash of high-profile recalls, and it's an important distinction that Chrysler (understandably) felt necessary to call out in bold print in its press release.
