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!"

Mopar maneuvers into SEMA with a multitude of modified models

As the aftermarket and performance arm of Fiat Chrysler Automobiles, Mopar has a duty to extract everything from the company's models that it can, and there's no better place to show all of its work off than the annual SEMA Show.
Dodge really gets in on the act this year with several customs to show off different parts of the brand's performance heritage. Perhaps the most interesting among them is the track-prepped Viper ACR Concept (pictured above). It wears a custom body kit to produce even more downforce, thanks in no small part to a monstrous wing at the back. To shed weight, most of the interior is stripped out, as well. Next up, the Challenger T/A Concept takes inspiration from '70s Trans-Am racing in a livery of Sublime Green and matte black paint. The center scoop in the hood keeps the 6.4-liter V8 fed with cool air, and the special's 20-by-9.5-inch matte black wheels keep it planted in the corners.
Also getting the once-over from Mopar is the Charger R/T. It wears the division's body kit, and under the hood, a cold-air intake keeps the 5.7-liter V8 breathing. The suspension is retooled to hold the road better with a coil-over kit, upgraded sway bars and strut tower braces for the front and rear. The company is also showing off a snazzy blue Charger with a mean look. The final Dodge getting work from Mopar is the Dart R/T Concept with bright, O-So-Orange paint and a matte black hood with a scoop hooked directly to the air intake. The performance-oriented design is finished off with a coil-over suspension and big brake kit, as well.

1972 Dodge Challenger on an M1009 CUCV military frame is YES

The subject of this post is cause for celebration, not reason to ask "But why?" We don't know why this random Craigslist seller chose to marry the body of a 1972 Dodge Challenger with the frame and axles from a 1987 Chevrolet M1009 military vehicle. We're here to appreciate it, thanks to The Drive, and maybe spend some time after dinner considering whether to buy it. Now that we're on the same page, an owner in Tucson wants to rid his garage — or his Bullet Farm — of what appears to be an exceptionally well built conversion. Starting from the bottom, the M1009 CUCV, for Commercial Utility Cargo Vehicle or "Cuckvee," emerged from a program turning K5 Blazers into supply rigs that were meant to support hardcore hardware like the AM General Humvee. The M1009 got GM's 6.2-liter Detroit Diesel V8, a TH400 transmission, an NP-208 chain-driven transfer case, a 10-bolt rear axle and 3.08 gears. Produced from 1983 to 1987, they returned "less than desirable" results in the field and the military unloaded them. Not much of that remains for this build. The diesel got dropped, replaced by a 5.7-liter GM gasser with a four-barrel carb and long-tube headers, shifting though a 4L80E automatic transmission attached to a U.S. Shift Quick 1 transmission controller in the cabin. The seller doesn't mention output, but if it's a more recent Chevy 350 then it'll certainly provide a healthy bump over the maximum 160 horsepower from the diesel, especially running through a custom Flowmaster dual exhaust. An NP-205 two-speed transfer case switches between 2H, 4L, and 4H. The Dana 44 front and Dana 60 rear axles feature lockers and 3.52 gearing in back. Skyjacker Black Max provides the suspension to keep the 37-inch BFG KM2 on the pavement or the dirt. About 11,000 miles ago the owner rebuilt and upgraded the drivetrain, installing new accessories like a high-rise intake, four-core radiator, new alternator and Holley fuel pump. Losing the K5 body for an E-body Challenger cap means losing M1009 features like the rifle rack and gas can mounts. But you gain style, something real hard to find on a vehicle stout enough to back you up when you tell the crew, "I've been to hell and I'm going back." As part of that rebuild a few miles back, the minimalist interior got all new panels, dash and custom gauges, headliner, seats, and a Sony audio system with Alpine amps, a sub, and Kenwood speakers.
