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!"

First 1K next-gen Mustangs to carry 2014 1/2 model year?

A new report from Mustangs Daily, citing insider sources at Ford, tells us that the Blue Oval will produce 1,000 next-generation Mustangs with the model year designation of 2014 ½, to celebrate the 50th anniversary of the storied marque. The commemorative half-year designation is a rumor that's been swirling in Mustang forums for quite some time now, and seems more plausible than ever with this most recent report. Certainly it's not far-fetched to believe that Ford will want to make a big deal of the golden anniversary for its most-loved model.
The story (compiled by Drew Phillips, who runs the aforementioned Mustang site when he's not directing the photography on these pages) goes on to say that the limited-run cars will be the first built on the new Mustang platform internally known as S550 (and spied testing in the attached gallery). Each car is said to carry a "special" VIN and build number, though no performance upgrades versus the 2015 cars to follow are in the works. A collector's dream then, rather than a weekend racer's.
