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!"

2015 Dodge Challenger SRT Hellcat has 707 glorious horsepower [w/video]

Hold onto your butts. "600-plus horsepower" is what we were told to expect from the 2015 Dodge Challenger SRT with its 6.2-liter supercharged Hellcat V8 engine. But as we've just learned, those were incredibly conservative numbers. Dodge has officially announced that the range-topping Challenger will hit the asphalt with 707 - seven hundred and seven - horsepower, making it the "most powerful muscle car ever."
Of course, 707 hp is only part of the story, as the Hellcat has also been confirmed to produce 650 pound-feet of torque. All that power will run exclusively to the rear wheels through an eight-speed automatic transmission that differs from other Challengers. The new gearbox, 8HP90 (rather than the 8HP70) is "upgraded to handle the extra power and torque," says Dan Reid, SRT's manager of product design and motorsports.
We certainly hope you're prepared to spend a ton of money replacing tires.

Somebody created a Dodge Challenger SRT Demon droptop

The Dodge Challenger SRT Demon is a vehicle built with one purpose in mind: going fast down a drag strip. Weight is the enemy when it comes to acceleration, and one surefire way to add weight to a car is to make it into a convertible. However, that’s exactly what one Demon owner decided to do to their Challenger. Motor Authority spotted this Plum Crazy Demon convertible conversion for sale online, and the dealer and builder even spilled a few details on the car itself. This particular conversion was done by Droptop Customs, a shop with experience, having previously converted a couple Challengers into convertibles for Shaq in Miami. However, ripping the roof off the 840-horsepower Demon is no small task. ThatÂ’s a ridiculous amount of horsepower to handle for a car that has lost a fair amount of structural rigidity from removing the roof. The Droptop Customs sales manager told MA about the changes that were made to make this build work. To begin, the frame rails were reinforced with 1x2-inch pieces of metal. Then, the shop added diagonally-mounted metal braces underneath to resist twist. Even more structural supports were added to the trunk, front and rear shock towers, and gussets were added to the bottom of each door to keep them from moving. Lastly, the shop boxed the connection of the front rails to the engine cradle. No specifics about weight gain were provided. There is one sad bit of news about this Demon, though. The dealer told MA that itÂ’s currently on consignment, despite being listed for sale on FCA dealership Cape CoralÂ’s website. ItÂ’s priced at an eye-watering $145,995. But the new owner wonÂ’t have to manually put down the top! ThatÂ’s right, itÂ’s powered, and itÂ’s supposed to take about 20 seconds to lower or raise into place while stationary. Somehow, the car has only 172 miles on it, so itÂ’s hardly been used. We have no photos with the top up, so youÂ’ll have to settle for top-down photos for now. It looks like a professional job through and through, and we actually dig the convertible look. Plus, who doesnÂ’t love Plum Crazy?
