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!"

Ford Mustang GT500 successor spied near SVT

Details about the next-gen Ford Mustang are scarce, and there's even less information out there about the upcoming replacement for the Shelby GT500. Previously rumored to drop the Shelby name and wear the GT350 moniker, the highest-performance Mustang has just been spotted testing near Ford's SVT operations.
Despite being cloaked in heavy camouflage, we can instantly tell this prototype is different from other Mustang spy shots we've seen in the past. Aside from the Shelby-spec wheels, quad exhaust outlets (previous spy shots show only two) and beefier brakes, this car also has air intakes on the hood and front fenders. These elements help to neither prove nor dismiss rumors that the next SVT Mustang will be naturally aspirated. It also looks like Ford is may be planning some changes to this car's rear suspension, as there is some extra camouflage added beneath the rear end of this prototype.
As a bonus, these spy shots also give us our first look inside the new Mustang, revealing a new steering wheel (with more buttons) and a glimpse of the dual-pod instrument gauges. Check out past spy shots of the 2015 Mustang showing off its new face and driving around town.

Ford Mustang Shelby GT500 has a bit of a dyno issue

We're of the mind that each and every dyno should come with Murphy's Law painted in big, visible letters down the side. For every ten successful dyno runs out there, it seems there's one where events to horribly wrong. Take, for example, the video below. The clip shows what happens when a Ford Shelby GT500 and a mobile dyno have a bit of a disagreement at the Performance Expo 24 in Sherbrooke, Quebec. We won't spoil the results for you, but we will say there's some substantial carnage involved.
It's unclear just how much damage ensues from the dust up or whether anyone was harmed in the incident, but from the looks of things, everyone made it out without serious injury. If only we could say the same for the machines involved. Check out the video below.
