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!"

Weekly Recap: Ferrari plans to gradually increase production by 2019

Ferrari has long been known for the exclusivity of its performance machines. It's on a different level than Porsche, BMW, and Mercedes. But as it transitions to a new era of independence from Fiat Chrysler, Ferrari is going to get a little less exclusive. It's by design, and it means a subtle, slow ramp-up of production – a move Ferrari believes will ensure its future by meeting growing demand in new markets. The strategy was detailed in SEC documents filed this month as part of the company's pending stock offering. The files reveal Ferrari will gradually increase shipments to about 9,000 units per year by 2019. This is a reversal of Ferrari's 2013 plans to cap production at 7,000 cars annually, which it hit on the nose that year. Ferrari shipments inched up to 7,255 in 2014, though that's down from 2012's record tally of 7,405. Ferrari is a vastly different operation than it was in 2013. Longtime chairman Luca di Montezemolo stepped down last fall, and FCA chief executive Sergio Marchionne has been overseeing the company since then. Its IPO has attracted high levels of attention from enthusiasts and investors. As expected, demand has reportedly outstripped the availability of the stock, which has an estimated offering price of $48 to $52 a share. Speaking of more Ferraris, the company revealed a limited-edition model this week called the F12tdf (shown above). Based on the F12 Berlinetta, the car is a salute to the Tour de France endurance auto race that Ferrari dominated in the 1950s and '60s. The V12 engine's output increases to 769 horsepower, while weight is cut by 243 pounds – allowing for a sprint to 60 mph in 2.9 seconds. Dramatic carbon-fiber elements and a radical redesign of the body panels give the F12 a more dramatic look. It will be limited to 799 units over the life of the car. If this is how Ferrari is increasing production, we're more than okay with the company's new strategy.
