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!"

Dodge Viper recall requires small-handed mechanics

It has been over a year since Chrysler first announced its recall of 3,660 2003-2004 Dodge Vipers because the airbag could suddenly deploy. The repairs are finally beginning, and it appears to be a nightmare for mechanics.
According to the automaker's filing with the National Highway Traffic Safety Administration, the airbag control module can fail, which causes the bag or the seatbelt pre-tensioner to deploy without warning. It took over a year to design the new parts, according to The New York Times. However, Chrysler finally has a new "jumper harness with an in-line diode filter circuit" ready to fix the problem.
The dilemma now moves to the mechanics who have to actually install the part. A 47-step guide from Chrysler explains that the procedure should take about two hours. It's not an easy job, though. Most of the dashboard has to be taken apart, and the instructions include this helpful bit of advice: "Installing the jumper harness and filter box into position is not an easy task. Patience, perseverance, and small hands are required." We wish the best of luck to them. The fix comes just in time for the Vipers to enjoy the summer sun.

Chrysler recalling 67k trucks with manual transmissions

Earlier this month, Chrysler announced the recall of some 280,000 pickup trucks over concerns that their axles could seize up. Now the automaker has announced an entirely separate recall of another 66,819 trucks over the springs that could break in the clutch ignition interlock switch. The recall affects Dodge Ram 1500, 2500 and 3500 pickups, as well as the Dodge Dakota and Mitsubishi Raider. The issue is relevant only to those trucks fitted with manual transmissions, from the 2006 and 2007 model years and manufactured between July 1, 2005, and July 31, 2006. Since a broken spring could, according to statements issued by the National Highway Traffic Safety Administration and FCA US LLC (previously known as the Chrysler Group) prevent the vehicle from starting, or cause it to move unintentionally once the ignition kicks over, the automaker will begin notifying owners of the affected vehicles just before Valentine's Day to bring their trucks into their local dealers to have the clutch ignition interlock switch replaced. FCA emphasizes, however, that the unintended movement would only occur "in rare cases" and only "if recommended starting procedures are not followed." Only one such case is known to have occurred, but it did regrettably result in a fatality. Statement: Clutch Ignition Interlock Switch December 29, 2014 , Auburn Hills, Mich. - FCA US LLC is launching a voluntary global recall of an estimated 66,819 older-model pickup trucks equipped with manual transmissions. The Company will replace their clutch ignition interlock switches at no charge to customers. An investigation by FCA US engineers discovered switches in certain model-year 2006 and 2007 pickups may be equipped with spring wire that differs from wire used in previous switches. The alternate wire may break and, as a result, the vehicles may not start. In rare cases, a vehicle may – if recommended starting procedures are not followed – exhibit unintended movement when its ignition key is turned. The Company is aware of one fatality related to this campaign. It stemmed from the single known accident involving this population of vehicles. The recall covers certain Dodge Dakota, Dodge Ram 1500, 2500, 3500 and Mitsubishi Raider pickups. Switches with the alternate wire were not used in any vehicles produced before July of 2005, or after June of 2006. The Dakota and Raider are no longer in production.
