Shelby GT500 and Roush Stage 3 go head to head at the drag strip

The Ford Mustang is a brilliantly affordable source of horsepower, with a base 300-plus-horsepower version available for well under $30,000. Jumping up to about $35,000 will get you a solid 420 horsepower from a high-revving V8, while those with some extra disposable income can get a pair of 600-plus-horsepower monsters. Both the Roush Stage 3 with its Phase 3 package and Ford's factory Shelby GT500 even crest the 650-horsepower mark, with 675 and 662 ponies, respectively.
Naturally, someone needed to find out which of these hi-po Mustangs was the quickest. And while this video is quite obviously a dealership commercial, at least there's some solid drag racing between two of the most powerful performance machines available for under $100,000.
With two NHRA drag racers at the wheel, the Stage 3 and GT500 go head to head for three races. Scroll down below to see the results in the full 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!"

Jay Leno is far beyond driven in his 1971 Pantera

Perhaps it's fitting that the band Pantera is known for its heavy metal music, because the DeTomaso Pantera is the automotive equivalent of a metal album. It's short, aggressive and makes a mean sound. It doesn't mess around either, with a Ford 351-cubic-inch (5.75-liter) V8 sending mountains of torque to the rear wheels. This week, Jay Leno takes us on a detailed tour of his '71 to show why it rocks.
There's a regular format to Jay Leno's Garage. It starts with Jay and maybe a guest taking a look at the car and talking about its history, and then they take it out on the open road. However, this video is practically a Pantera buyer's guide. Jay is adamant from the start that the last thing anyone should own is a stock example. To remedy this, he and his guest, the editor of the Pantera Club magazine, take viewers to school about some of the ways to turn them into even better performance machines.
No matter what you do to it, though, the Pantera requires that the driver adapt to it, not the other way around. For example, Jay isn't a big guy by most standards, but he has to cram himself into the cockpit with his shoes off and shirt partially unbuttoned just to go for a drive. Still, once out on the road, it all makes sense with that rumbling V8 and those Italian supercar looks. Scroll down to watch and learn a lot more about this uncompromising '70s performance car.
