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!"

Challenger A/T Unlimited Concept could be your next Hellcat-powered ORV

This past June I spent an excellent day hanging out with Joey Ruiter, driving and discussing his Reboot Buggy project. Before heading home, I let him know that he was more than welcome to keep me abreast of whichever new automotive project he'd get into. You can never have too many car designers and one-off fabricators in your Rolodex, right?
Ruiter recently made good with the follow-up, emailing me with details on this Dodge Challenger A/T Untamed Concept that pushes a lot of hot buttons for the muscle car and off-roading enthusiasts.
This all-terrain Mopar is a lot more than a Challenger body dropped on a truck chassis, too. A materialized version of the A/T would included a completely new, long-travel suspension, skid plates, body armor and rock sliders, and obviously flared fenders to help accommodate a hellacious set of off-road-ready tires. The dramatically revised underpinnings would be topped with a slick graphics package and a killer lower light bar, all making the A/T look quite cohesive in its own, radical way. And the result would be a car no longer limited to mere road-driving.

What's the deal with Chrysler demanding colleges crush their Vipers? [w/video]

Students and teachers at a Washington community college are up in arms following an order from Chrysler that it must destroy the pre-production Dodge Viper that was donated to the school's automotive technology program ten years ago.
The Viper in question is said to be the fourth off the production line, based on its VIN, and has had its emissions controls disabled, allowing its ten-cylinder engine to produce 600 horsepower, according to a report from Yahoo! Autos. As one of the first Vipers ever produced, the school's AT instructors claim it could be worth $250,000 in a museum, while a local news report purports that Jay Leno once tried to purchase the car, but the sale was prevented by Chrysler.
As pointed out by our friends at Autobytel, though, there are a lot of things in this story that don't quite add up. Immediately noticeable from the news report embedded below - which shows the car at South Puget Sound Community College - is that the car in question is not a 1992 model. When the Viper went on sale in 1992, it was only available as an RT/10 with a (flimsy) soft top, like the red car shown above. But the car featured in the report from KING5 News (inset image) is clearly a hardtop Viper GTS, which didn't enter production until 1996. And even if, as reported by a local newspaper, the hardtop featured is a prototype, it doesn't explain the lack of another iconic feature of the first Vipers - their distinctive side pipes. This kind of pokes holes in the school's argument that this is the fourth Viper to ever roll down the line. At best, this appears to be a pre-production Viper GTS.
