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!"

Travis Pastrana signs with Dodge for another year, brings partner Bryce Menzies [w/video]

Dodge and SRT Motorsports announced that the Dodge Dart will be returning for its sophomore season of the Global Rallycross Championship with a two-car team fielded by Pastrana Racing. Travis Pastrana drove his GRC Dart to victory lane in the fourth race of the car's inaugural season, and his race team is looking for even more success with the addition of off-road racer Bryce Menzies behind the wheel of the second car.
The 2013 GRC season kicks off on April 21 in Brazil with plenty of dirt-spewing, ramp-jumping action. Scroll down for a video from the cars' main sponsor, Red Bull, and a press release from Chrysler.

2015 Dodge Charger R/T NHRA Funny Car burns rubber into SEMA [w/video]

Fiat Chrysler Automobiles is showing off a completely redesigned Dodge Charger Funny Car at this year's SEMA Show in Las Vegas and it's ready to blow through the NHRA timing lights next year. Initially, the shape might look like any of the other entrants in its class burning through the quarter mile, but this is the first comprehensive rethink for the racecar's aerodynamics since 2006, says Dodge.
Draped in classy red and black Mopar livery, the 2015 Dodge Charger R/T NHRA Funny Car tries to share the front and rear styling with its roadgoing counterpart, plus the scallops along the side, but this racer is all about crossing the finish line first.
The major goals for the redesign included making the body stronger and lighter without sacrificing aerodynamics, and that has been done with materials like Kevlar and carbon fiber. However, engineers have accomplished even more. By moving the cockpit further back, they've increased engine clearance and improved driver visibility.
