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!"

Dodge Challenger SRT Demon TransBrake eliminates the need for brake torquing

Performing the perfect launch is key to drag racing. In order to get consistent starts, the engineers behind the Dodge Demon developed TransBrake, a system that holds the output shaft of the automatic transmission to keep the vehicle stationary until launch. Rather than the traditional method of two-foot brake torquing, the system is triggered by pulling the shift paddle for quick and consistent launches. According to Dodge, the main benefit of TransBrake versus a two-foot setup is a quicker power delivery and higher engine launch torque potential. The system gives brake-free launches up to 2,350 RPM, a 105-percent increase in launch boost pressures, and a 120-percent increase in engine launch torque. Dodge also claims that using the paddle provides a 30-percent better reaction when compared to using your feet. In addition to shifting duties from your feet to your hands, the Demon's TransBrake will preload the driveline. Torque is loaded at the wheels, not the transmission. That means full torque delivery 150 milliseconds after the shift paddle is released. It should also help reduce the driveline shock that occurs when those 315 section rear tires get near-instant grip. The reveal is coming near.

Fiat Chrysler profit up as it closes in on retiring its debt

MILAN — Fiat Chrysler Automobiles reduced its debt by more than expected in the first quarter, putting the carmaker well on course to become cash positive later this year. Chief Executive Sergio Marchionne expects to cancel all debt during 2018 — possibly by the end of June — and generate around 4 billion euros ($5 billion) in net cash by the end of the year. Marchionne has said that forecast does not include any one-off measures, nor the impact of the planned spinoff of parts maker Magneti Marelli, which he hopes to execute by early 2019. The world's seventh-largest carmaker said on Thursday net debt had fallen to 1.3 billion euros ($1.6 billion) by the end of March, well below a consensus forecast of 2.6 billion euros in a Thomson Reuters poll of analysts. FCA said capital spending fell 900 million euros in the quarter due to "program timing," which analysts said implied higher investments for the rest of the year. The Italian-American group said first-quarter operating profit rose 5 percent to 1.61 billion euros, below a consensus forecast of 1.74 billion, as a weaker performance from its North American profit center weighed. Shipments there were higher due to the new Jeep Wrangler and Compass models. But currency moves hit revenues and earnings, and costs related to new product launches added to the pressure. FCA's shift to sell more trucks and SUVs boosted margins yet again in North America to 7.4 percent from 7.3 percent in the same quarter a year ago, although they were down from the 8 percent recorded in the preceding three months. Marchionne, preparing to hand over to an internal successor next year, is close to his goal of ending a margin gap with larger U.S. rivals General Motors and Ford. The 65-year-old has said becoming debt free and being able to compete on a par with U.S. peers would mean FCA no longer needed a partner to survive and could well succeed on its own. The CEO has previously said tying up with another carmaker would help to meet the huge costs in an industry investing in electric vehicles and automated driving. FCA shares fell immediately after the results, but recovered to trade up 3 percent at 19.71 euros by 1150 GMT, outperforming a 0.4 percent rise in Europe's blue-chip stock index.
