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 spied exercising supercharged Hellcat Hemi V8

One of the prime complaints against the Dodge Challenger is that, even in SRT8 guise, its 470 horsepower is responsible for hauling over 4,200 pounds of vehicle. For comparison, the 420 hp in the Ford Mustang GT only has to deal with 3,618 lbs. Things only get worse from there, as the higher-performance variants of both the Mustang and the Chevrolet Camaro are far more powerful than an SRT8 without adding on much heft.
So what is Chrysler to do? The correct answer is add a whole lot more grunt to its hefty two-door and even the odds. That's where the all-new Hellcat engine comes into play. We reported on this engine in May, and suggested that the Hellcat, a supercharged powerplant based on a 6.4-liter V8, would easily generate 500 to 570 hp and could likely arrive boasting more than 600 ponies.
Chrysler's ace in its sleeve has now been spied testing, with a number of Hellcat-equipped Challengers running the potent new engine both in more urbanized areas and under the sun of Death Valley. The hoods on these testers have been raised to accommodate the engine, and that camouflage over the fascias of these prototypes is there to hide a larger air intake. We also note what appears to be a new split grille under wraps. As for power output, our spies are now suggesting a Viper-equalling 640 hp from the Hellcat-equipped cars.

2016 Dodge Challenger and Charger Hellcats see doubled production

The launch of the Hellcat supercharged V8 in the Dodge Challenger and Charger for the 2015 model year was a massive success. The one-two punch of muscle cars probably grabbed the brand more headlines than it had seen in ages by offering a world-beating 707 horsepower from the growling engine under the hood. The only real wrench in the works was keeping up with all of the orders. For 2016, Dodge might have fixed that little problem with plans to make more than twice as many of these mean machines Despite production seeing a massive boost, a few customers with orders for 2015 examples will need to wait just a little longer to experience those 707 ponies. The automaker will cancel any unscheduled, sold orders for the current model, but those buyers will receive a discount on the 2016. Similar to last year, dealers will earn their allocation of the muscle cars based on Dodge sales and how long the Hellcats stay on their lots. There are some very tiny changes for any buyers who are holding out for the 2016 Hellcats, too. Mechanically, they are identical to the 2015s with a 6.2-liter supercharged V8 and eight-speed automatic. The interiors see some improvements, though. Both the Challenger and Charger now receive standard Laguna Leather upholstery and an improved 8.4-inch Uconnect system with navigation, an HD radio, and five years of SiriusXM Travel Link and Traffic. Orders for both open in the second week of August, and production actually begins in September in Brampton, Ontario, Canada.
