Roadkill pits every project car against each other

The guys behind Motor Trend's monthly Roadkill series have collected nine of their favorite project cars from their videos and pitted them against each other in a battle royale to determine a winner. It's 44 minutes long, but it's completely worth the investment of time.
The cars run the gamut from a 1973 Chevrolet Ramp Truck, a 1975 AMC Pacer and a legitimately impressive 1967 Chevy Camaro, and they are pitted against each other to see which is the fastest around an autocross course. The drivers include Roadkill's two hosts and Motor Trend's Johnny Lieberman and Carlos Lago. It's reminiscent of the best episodes of Top Gear and worth a watch.
So it's the weekend - the perfect time to relax. Grab your preferred beverage, get comfortable and enjoy 44 minutes of some seriously ratty but utterly cool project cars as they are throttled within an inch of their lives (or past it). Scroll down to check out the video.

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 Hellcat ringtone revs up [w/video]

The best (or worst, depending on your views) thing about smartphones is that you're able to carry lots, and lots of useful stuff around in your pocket. That means you can always have a phone, messaging service, email, flashlight, calculator, dictionary, encyclopedia, and literally thousands of other things on your person at all times. Now, we can add one more thing for you to carry about in your little slab of aluminum, glass and plastic - a Dodge Challenger SRT Hellcat.
Now, you obviously can't carry around a 707-horsepower muscle car around in your pocket. That'd be ridiculous, impractical and uncomfortable. You can, however, carry around the noise made by said muscle car's 6.2-liter, supercharged Hemi V8, thanks to a new, free-to-download ringtone from the folks at Dodge and SRT.
We can't embed the ringtone here, so if you'd like to hear exactly how it'll sound when your phone goes off, you'll need to head over to the SRT Hellcat's page. If that's more trouble than it's worth, the same ringtone was attached to a tiny speaker on the press kit for the mighty Challenger, and was captured on video by our own Seyth Miersma (don't worry, he's already been soundly dressed down for shooting a video in portrait mode).
