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!"

Watch 1,414-hp worth of Dodge Challenger SRT Hellcat do stereo burnouts

When Dodge announced that the 2015 Dodge Challenger SRT Hellcat would produce 707 horsepower and 650 pound-feet of torque from its supercharged 6.2-liter V8, automotive enthusiasts were shocked. The company had promised us that it would be powerful, but no one expected for the muscle car to post even larger numbers than the range-topping Viper.
Car and Driver recently got ahold of two new SRTs and decided that the only proper way to show them off was by lighting up the rears in stereo. With a combined 1,414 horsepower, the pair of them make burnouts from the Hellcat V8 look as easy as breathing. The tires start spinning at the slightest provocation and just don't stop. If you buy one of these, it looks like you and the employees at the local tire store are going to be on a first name basis.
Scroll down to watch these two Hellcats to lay down enough smoke to alert the local hook and ladder trucks.

Dodge performance trio thrashed on Roadkill

Of all the shows that Motor Trend does, Roadkill is probably the last one we'd pick to evaluate the latest performance automobiles. That's not a slight against David Freiburger or Mike Finnegan, who host the show: they're certified gear-heads and the go-to guys when it comes to hot rods, rat rods and anything grungier than it is shiny. But as exemplary as they are of Detroit muscle, the Charger Hellcat, Challenger Hellcat and Viper are also shiny new pieces of metal. Still, since it will now be sponsoring the show, someone at Dodge apparently thought it would be a good idea to hand Freiburger and Finnegan the keys to the company's top performance models. So to ring the best out of them, they solicited help from some of their colleagues at MT, gained access to a closed-down air strip, devised as many ways as they could to destroy the tires, and proceeded to set about doing exactly that. Watch the grin-inducing mayhem unfold in the half-hour clip above. Related Video:
