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!"

2015 Mustang-based Saleen S302 to boast as much as 640 hp

The Ford Mustang is obviously a famous performance vehicle in its own right, but it often works even better as a platform for the aftermarket to upgrade. With the all-new 2015 model just now hitting the scene, the famous tuners at Saleen are getting their improvements for the new pony car ready for the world. After recently teasing it, the specs for its fresh S302 model are officially here, along with a first look at it in profile.
Of course, the biggest question on everyone's mind is how much power the company can get from the Mustang's V8. With the 2015 V8 model rated at 435 horsepower and 400 pound-feet, Saleen expects to bump the Ford factory numbers slightly to 450 hp and 410 lb-ft in naturally aspirated form, or with the benefit of a supercharger, it will rocket the engine's output figures to 640 hp and 565 lb-ft. No matter which powerplant a buyer chooses, there are a wide variety of available final-drive ratios with a six-speed manual or automatic gearbox.
Available as either a coupe or convertible forms, Saleen will offer its S302 in three trim levels - White Label, Yellow Label and Black Label. The White Label is the only naturally aspirated one of the bunch, but it still benefits from upgrades like a new exhaust, limited-slip differential, improved suspension, heat extractor hood and rear wing.
