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!"

Ken Block ain't got a care about ruining his wheels

During a drifting session at Irwindale Speedway in California, Ken Block made a boo-boo that would send a number of drivers immediately back to the infield. But there's an answer to "What do you do when you bash the wall while drifting and your wheel explodes?" and there's completely different answer when the question begins with the phrase, "When you're Ken Block..."
Instead of us telling you how Block handled the calamity in his Ford Fiesta competition car, you can watch it happen in the video below. You can probably also guess what it is - but it's more fun to watch.

Ford Fiesta banned from SCCA autocrossing because of rollover risk

Autocross can be a great way to break into motorsports, especially at SCCA events that allow run-of-the-mill, street-legal vehicles to be run through the cones in parking lots across the country. But while a wide array of vehicles are eligible, not every one is. And now the Ford Fiesta has been removed from the list of qualifying vehicles in the Sports Car Club of America's Street category for solo events. The removal of the Fiesta was publicized in the latest issue of the SCCA's Fastrack News bulletin, which stated that, due to roll-over risk, Fiestas "do not meet the requirements and are to be removed" from the HS category of eligible vehicles. H Stock (or HS for short) is the lowest category of vehicles certified by the SCCA for use in sanctioned events. The disqualification applies to Fiestas from the 2011 model year onwards, and does not apply to the Fiesta ST, which remains eligible. Of course the Fiesta isn't the only model deemed ineligible for SCCA autocross events. According to Jalopnik, other small hatchbacks and crossovers including the Dodge Caliber, Fiat 500, Scion xB and iQ, Nissan Juke and Mini Countryman are also prohibited from competition. We've reached out to both Ford and the SCCA for clarification on the issue, and will issue an update if and when we receive any substantial information.
