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!"

Ranking Dodge's Charger Hellcat with the fastest sedans in the world

"This is a car that most brands would never bring to market." - Tim Kuniskis
Dodge CEO Tim Kuniskis had reason to be confident, perhaps even a bit cocky at the reveal of his brand's newest halo car, the 2015 Dodge Charger SRT Hellcat. As he said simply, it's the "quickest, fastest and most powerful sedan in the world."

eGarage interviews a couple with 65 Vipers

Owning multiple vehicles can be a hassle worth enjoying if you're willing to spend the time and the money required to acquire and maintain them. But when it's hard to make ends meet while underused valuable hunks of metal, plastic and rubber sit happily taking up garage space, journeys into the depths of other people's well-developed automotive obsessions will either bring you and your cars closer together, or compel you to sell them off before you become one of those fanatics. A recent video by eGarage is one of those journeys, and it's not for the faint of heart: D'Ann and Wayne Rauh own 65 Dodge and SRT Vipers in a collection of automobiles that exceeds 100.
We're not sure if the couple has developed heat-resistant calves from stepping over Viper door sills made burning-hot by side-exhaust pipes, but we wouldn't be surprised if they did. We did learn that their obsession with the no-holds-barred sports car started in 2006 with a trip to a dealership to buy just one Viper, which goes to show how innocently car obsessions can start. But the Rauhs seem to be doing just fine - perhaps better - 64 more Vipers later.
Watch the video below for the full story and to see what eGarage claims is the world's largest Viper collection.
