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!"

Ringbrothers shows off Coyote-powered 1968 Mercury Cougar

We'll openly admit that not every SEMA build is our cup of tea. But this? A tastefully resto-modded 1968 Mercury Cougar with a 460-horsepower Ford Mustang V8? Yeah, this is right in our wheelhouse. Sadly, there was no in-pwerson SEMA show in 2020, so we missed out on gems like this one. SEMA or no SEMA, the aftermarket carries on, and co-owners Jim and Mike Ring of Ringbrothers (get it?) saw no reason to let their time and effort go to waste.  When they're not building wild customs (see: 1,100-horsepower 1972 AMC Javelin AMX) or more subtle showcases (such as this Cougar or their 1971 K5 Chevy Blazer build from 2018), the folks at Ringbrothers crank out factory reproduction parts, whether for old-fashioned restoration or modification purposes. While '60s muscle cars are recurring build subjects for the two, the Cougar was the first of its kind they tackled.  Keeping it in the family, Ringbrothers sourced a Ford 5.0-liter "Coyote" V8 and a 10-Speed Automatic (lifted from an F-150 Raptor, incidentally) for the build. They didn't stop with the driveline, of course. The suspension was overhauled with a little help from DSE and a set of HRE Series C1 C103 Forged 3-Piece wheels were thrown over upgraded brakes.  "We put our heart into each car we build, and this Cougar is no exception," Jim said. "The finished product is mild and classy, yet any enthusiast instantly knows it's not stock. I imagine this is what Mercury designers would have come up with if they were building the Cougar today." "While we couldn't bring the car to the SEMA Show, we hope it can be shown to the public soon," Mike said. "We had never done a Cougar before, so this was a fun build. I love working with new shapes and coming up with new ideas." There's plenty to appreciate about this Cougar apart from the mechanicals, too. The finish is Augusta Green Metallic (courtesy of BASF), which was a factory color in 1968. You may know it by another name: Highland Green. There are a few custom exterior touches, but they're quite subtle and styled to be period-correct. The interior was also restored and updated, and it's where you'll find the only thing we're not fond of: that big, fat truck shifter. Gearbox choices notwithstanding, it's a bit of an eyesore. But considering how gorgeous the rest is, we'll give it a pass.  Related Video:

Ford Shelby GT350 Mustang to cost $52,995?

The 2015 Ford Shelby GT350 Mustang was one of the shining stars of this year's Los Angeles Auto Show. And the Blue Oval's latest muscle car might even have reason to burn a little brighter if a recent rumor about its price proves true. Best of all are rumors that an even more potent version of the Shelby is potentially on the way. According to Horsepower Kings citing unnamed Ford sources at the LA Auto Show, the 2015 GT350 carries a starting price of $52,995, and the Tech package adds a further $2,995 on top of that. There's also the claim of a Track package for an undisclosed price. However, it doesn't look like LA is the last we'll see of the newest Shelby because the source also alleges that a top-rung GT350R is under development with bigger brakes, modified aerodynamics and sportier tires. This rubber-burner is reported to be unveiled at the North American International Auto Show in Detroit in January. Assuming these claims are correct, it puts the Shelby in fighting form against its two Chevrolet Camaro rivals. Ford reports that the GT350's 5.2-liter V8 pumps out over 500 horsepower and more than 400 pound-feet of torque. At $52,995, it would undercut by a couple of grand the $55,505 (before destination) base price of the 580-hp 2015 ZL1. The super 'Stang might also beat the 505-hp Z/28 with its power rating, while being vastly cheaper than the track-focused Camaro's $72,305 price. This could be quite the performance shoot-out.
