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!"

2014 Ford F-150 Tremor adds some sport to shake things up

Like most quakes, the 2014 Ford F-150 Tremor caught us by surprise. We weren't expecting Ford to offer up another version of its best-seller so soon before the truck's full redesign, but that's exactly what the company is doing.
While Ford calls the Tremor a "performance truck," the new pickup doesn't play on the same level as the SVT Raptor does on dirt, or even the long-gone SVT Lightning did on pavement. Think of it as a parts bin sport truck that probably does a better job looking the part than acting it. The Tremor utilizes the same twin-turbo, 3.5-liter EcoBoost V6 available across the F-150 lineup, producing 365 horsepower and 420 pound-feet of torque, but matches it with a 4.10 rear axle - the shortest final drive ratio you can get in an F-150 - for the strongest possible acceleration.
The Tremor does do a decent job looking the part. Available only in short-wheelbase, regular cab configuration with your choice of two- or four-wheel drive, it struts around wearing the F-150's FX Appearance Package, flat black accents, 20-inch black wheels, HID headlights and a special exterior graphics package. The Tremor is the only regular cab F-150 with a flow-through center console, which means it also gets a floor-mounted shifter and bucket seats that are covered in black leather with red piping. Some brushed metal accents and steering wheel with red stitching round out the interior upgrades.
