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!"

Hurst Edition Trans Am proves the Screaming Chicken will rise from the ashes

It seems the Pontiac Trans Am steadfastly refuses to die. Ever since Chevrolet was granted a retrofied Camaro to compete with the Ford Mustang, Pontiac lovers have lamented the loss of this 1970s icon. And, looking at the Hurst Edition from Trans Am Depot, shown here at the 2012 SEMA Show, may explain what all the fuss is about.
It's not going to appeal to everyone's muscle-car tastes, but there's certainly room for a brash-and-bold black-and-gold Special Edition in many a Trans Am lover's garage. After all, if you want the keys to a custom pony car, you'll certainly get noticed in this one. If this scheme isn't your bag,, you can alternatively order your Hurst Edition in white and gold or silver and black. Oh, and don't forget a color-coordinated Screaming Chicken on the hood.
No matter which way you choose to go, your inner Burt Reynolds will appreciate the Eibach suspension kit, forged wheels with Pirelli PZero tires, functional shaker hood, fender air extractors, rear spoiler and, of course, a Hurst shifter inside. The interior is emblazoned with all manner of special touches, including a Hurst dash plate and T/A stitching on the Katzkin two-tone leather seats.

Corvette Stingray designer lists five goals of new exterior shape

Redesigning an icon is a difficult task, especially when you've got a blank sheet of paper in front of you and the all-new C7 Chevrolet Corvette Stingray is intended to be your final objective.
General Motors has released a new short video featuring Kirk Bennion of the Corvette's exterior design team, talking about the challenges of sculpting Chevrolet's new flagship sports car and the five goals the team had to keep in mind as it worked. In the end, Bennion's team had the pleasure of seeing their hard work take center stage as the Corvette captured the world's eyes at the Detroit Auto Show earlier this year.
