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!"

Corvette Z06 and Viper TA square off at the strip

There are many long-standing grudge matches among automobiles: 911 vs GT-R, Mustang vs Camaro, Ferrari vs Lamborghini... but as far as high-end American metal goes, it doesn't get much more legendary than Viper vs 'Vette. So after Chevy released the new Corvette Z06, we knew it was only a matter of time before it would have to square off against the Viper TA. And what better place to pit these two parallel pillars of American performance than on the drag strip? Fortunately that's just what we have here. In one corner, the 2014 Dodge Viper TA, with its 8.4-liter V10 pumping out 640 horsepower and 600 pound-feet of torque. In the other, the 2015 Chevrolet Corvette Z06, the supercharger on its 6.2-liter V8 more than making up for the discrepancy in displacement and cylinder count to produce 650 hp and just as much torque. But numbers don't tell the whole story, so watch the video clip to see which reaches the end of the quarter-mile first.

Highway To Hellcat: Dallas to Vegas with 2,000 HP

Fort Davis, TX. Early November. Late Sunday afternoon. The 1,200 residents of this small town are using their day of rest to quietly enjoy the breeze rolling off the hills. There's an older couple walking down the street, holding hands. A young lady working at a general store, where milkshakes and antacids are purchased at the same counter. It's a peaceful, quaint scene, right down to the tumbleweed rolling across the street and the rickety wooden porches outside the old storefronts. I hit the throttle of the 2015 Dodge Charger SRT Hellcat while turning left onto the road leading toward the town square, sending the sedan's rear end swinging to the right with a few puffs of rubbery smoke. I coast down to the 25-mile-per-hour speed limit and spot the line of Challengers, Chargers, and Vipers in my rear-view mirror, the drivers all mimicking my quick jolt of enthusiasm before pulling up the reigns on their V8s and V10s and idling into Fort Davis. Our posse would roll some 5,000 horsepower of pure American muscle into that small Texas town that day. It was only the first stop on an epic journey that would take us from Dallas to Las Vegas, on a winding route down toward El Paso, up through New Mexico, Arizona, and finally north into Nevada, ending at the ritzy Palazzo casino and hotel on the Vegas strip. It was an opportunity to see parts of America I never knew existed, and a chance to bond with some American cars that until recently, I sort of failed to understand. And most importantly it was an opportunity to drive really, really hard. Charging Through Texas Unless you've driven across it, it's hard to understand the massive space that is Texas. In places, scanning 360 degrees of horizon reveals absolutely nothing. Nothing. On its own, driving from Dallas to El Paso covers some 630 miles. Veer south to Fort Davis and you'll add another 70 onto that, not including the 75-mile Davis Mountain Scenic Loop where I found bliss behind the wheel of this insanely powerful sedan. I always expected to like the Charger Hellcat – comfortable seating for four (five in a pinch), equipped with the latest tech, wrapped in a stylish yet muscular body, like a quarterback in a tux. And it moves. The supercharged 6.2-liter Hellcat V8 pumps out 707 horsepower and 650 pound-feet of torque, which makes for one quick sedan, especially considering its heft.
