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!"

The final-year Viper special editions sold out so fast Dodge is adding more

Viper collectors don't mess around. After Dodge opened ordering for its 25th anniversary 2017 Viper models – some of the last ones that will be built – all of the cars were spoken for in just five days. The company managed to sell 206 cars, an average of about 41 per day. Compare that to the 241 Vipers sold through May of this year and you can see why special editions make good business sense. Demand was so strong that Dodge will add a sixth special-edition for the Viper's last year of production. Within the group of five initial special packages, the winner was the 1:28 Edition ACR; all 28 went in 40 minutes. Dodge sold the 31 VooDoo II Edition ACRs in two hours, while 25 Snakeskin Edition GTCs and 100 GTS-R Commemorative Edition ACRs took two days to sell out. The 22 Dodge Dealer Edition ACRs took five days – apparently the dealers were too busy taking orders for the other 184 cars they didn't have time to order their own. The additional anniversary car is called the Snakeskin ACR. Dodge will build "up to" 31 of them, which we're pretty sure means exactly 31 if the previous demand is any indicator. The count matches the 2010 run of Snakeskin ACRs and will take the final-edition total to 237. We don't have any photos of that one yet, but you can get a good idea of what it will look like from the Snakeskin GTC. This one features Snakeskin Green paint, obviously, with a custom snakeskin-patterned SRT stripe, the ACR Package, the Extreme Aero Package, carbon-ceramic brakes, the ACR interior, a serialized Snakeskin badge on the instrument panel, and a custom car cover with the owner's name by the door. It will be available to order in the middle of this month, which means it will be sold out well by the end of the month. Chances are these and many of the others will go to mega-collectors like Wayne and D'Ann Rauh of Texas, who, at last count, owned 79 Vipers. Seventy-nine. Like we said, Viper collectors don't mess around. Related Video:

MotorWeek revisits the awesome, original Dodge Viper

MotorWeek is bringing the automotive world a wonderful blast from the past with its latest Retro Review. Not only does the video feature the now-famous, original Dodge Viper, but this is also a chance to watch one lapping Pocono International Raceway in a test of track prowess. This segment was MotorWeek's first chance to unleash the Viper around a racecourse, and the show took advantage of the opportunity. In addition to the usual 0-60 mph and quarter-mile tests, the 400-horsepower V10 is let loose to do lap after lap. The clip offers a great dose of nostalgia and is worth a watch to remember the intense enthusiasm surrounding the Viper at the time.
