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!"

Detroit's new fleet of donated police cars have safety issues [w/video]

In a show of generosity in mid-August, Detroit's business leaders donated $8 million to the Police Department and Fire Department in order to buy 100 new police vehicles and 23 EMS ambulances. But now officers have discovered - and complained - that the police vehicles have glaring safety issues, Deadline Detroit reports. It is not made clear what models of the fleet vehicles - which include police versions of the Ford Taurus, the Chevrolet Caprice and the Dodge Charger - are affected by the safety issues.
Officers reportedly have complained that the Plexiglass partition separating front-seat officers and back-seat prisoners is easily breached, and that the front passenger seat is installed too close to the dashboard. Prisoners who manage to writhe out of their handcuffs can bend the Plexiglass and reach into the cockpit, and sitting too close to the dashboard can render airbags more dangerous and make officers more vulnerable to injury in a crash.
Mark Diaz, president of the Detroit Police Officers Association, received the complaints and reportedly said the vehicles would get safety updates addressing the issues. But Deadline Detroit reports that it checked some of the offending police cars and, as of the last few days, they hadn't been updated.

Chrysler extends fuel tank warranties on LX cars, NHTSA ends probe

The National Highway Traffic Safety Administration has ended its investigation of 153,817, 5.7-liter and 6.1-liter Hemi V8-powered 2006 Chrysler 300, Dodge Charger and Dodge Magnum models after reports of stalling. Chrysler has responded by granting a lifetime warranty on the fuel tanks for these vehicles.
NHTSA received 299 reports of engines stalling while the models were stopped or driving at low speeds, and began an investigation. The government agency found that the control valve shutoff float in the V8s' 19-gallon fuel tank could malfunction if the fuel had too high of an ethanol content. In many cases, the valve would break in the open position, allowing the tank to be overfilled, which would then cause the cars to stall. However, there were no accidents reported, and the vehicles could be restarted immediately.
There will not be a recall on these vehicles because, "the condition represents a low risk to motor vehicle safety and is adequately addressed by Chrysler's extended warranty," NHTSA said to The Detroit News.
