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!"

Viper owners raising money to retake the Nurburgring lap record

Nurburgring lap times – unofficial as they may be – are the locker room comparison contest of the automotive world. For several years, the lap record of 7:12:13 was held by a 2011 Dodge Viper ACR. The Viper and America were the rulers of the roost until the usurper, the Porsche 918, came in a stole the crown. The death knell is ringing for the Viper, and a group of owners are raising money to send the car to the 'Ring for one last chance at glory. The current Dodge Viper ACR is an astonishingly capable car. All of the flaws that make it miserable to live with everyday - stiff suspension, obnoxious exhaust, speed-bump-gouging splitter - make it one of the most formidable road-legal track machines ever created. Unfortunately, that single-purpose nature turned off a lot of customers, and slow sales have led to the end of Viper production. The Viper holds lap records on more than a dozen of tracks, but, like a driver winning the Indianapolis 500, only one belt notch truly matters. The ViperExchange is willing to supply two ACRs and two drivers well versed in the Nurburgring in order to retake the record. The problem with attempting to set the record is mostly down to logistics. According to the GoFundMe page, the total cost to send the cars, pay for the track, the supplies, and operating expenses is about $150,000 and $200,000. The group says this is entirely a volunteer effort and are asking for donations to fund the Viper's return. Those wishing to help replant the stars and stripes and fill the forests of Germany with the truck-like roar of an odd-firing V10 can donate online. If they fall short, donations will be returned.

Dodge Challenger SRT Hellcat's 707 storming horses can be yours for $60k

We love a good deal on high performance. It's what traditionally makes muscle cars so appealing - you get lots of speed, for not a lot of money. For 2015, Dodge has taken this to its logical extreme, offering its new 707-horsepower, supercharged, V8-powered Dodge Challenger SRT Hellcat for just $59,900. For those wondering, that works out to just about $85 per horsepower, which when compared with a typical budget performance car, like the $24,995, 210-hp Volkswagen GTI ($119 per hp), demonstrates the Hellcat's astonishing value.
The information was revealed by a photo (click on the inset image to expand) taken at this week's Portland launch event (our man Seyth Miersma is just now on the ground and will have a full report on the madness that is the Hellcat soon) for the entire 2015 Challenger range, and reveals the Hellcat's price alongside its high-powered competitors from Ford and Chevrolet.
The discontinued 662-hp Mustang GT500 started at $56,000, while the 580-hp Camaro ZL1 starts off at $58K. Indeed, the only muscle car that outprices the Hellcat is the track-focused Camaro Z/28, a car that we're guessing could still wallop the Hellcat on the right piece of track, despite being down over 200 hp.
