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 drives a 1970 Dodge Charger with 1,650 horsepower

When Jay Leno says a vehicle might have too much horsepower, he's got our attention piqued. That's exactly what he thinks about the 1970 Dodge Charger Tantrum from Wisconsin-based SpeedKore Performance. While it still looks like a classic muscle car, the front end now features a carbon fiber hood and fenders. Underneath the lightweight parts, there's a twin-turbo, 9.0-liter Mercury Marine offshore boat racing engine with an astonishing 1,650 horsepower, or an only slightly less asinine 1,350 hp on pump gas. Jay is very mechanically intrigued by the Charger at the beginning of this video, and puts it on the lift to take a look at the underside. The engine plumbing is a thing of beauty, and the mill packs a massive radiator and intercooler to keep things running cool. Leno's drive in the Tantrum is especially interesting. The beastly engine is difficult to control, and anything above half throttle in most gears can spin the rear tires. The significant turbo lag also makes the power unpredictable. When Jay finally finds a straight piece of road, he puts the hammer down and rockets into the distance. And, of course, you know Jay's not going to end the video without some suitably smoking tires.

Is this the 2020 Dodge Charger SRT Hellcat Widebody?

Last month we told you about the heavy anticipation that Dodge will release Charger Widebody versions in SRT Hellcat and R/T Scat Pack trims for 2020. Now we have strong visual evidence to back it up. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Instagram user and self-described motorsports enthusiast zl1_dre_92c captured a brief video while out driving around suburban Detroit Tuesday of what appears to be a Charger SRT Hellcat Widebody with more pronounced fenders and distinctive graphics passing him in traffic. We can see SRT spelled out on the lower passenger front door and on the rear fascia, and curiously, it appears to be sporting a Florida license plate. Mopar Insider says a source told it that's because Dodge was trying to keep the muscle car away from the usual prying eyes in Detroit and instead has been running it around its secret testing facility near Naples, Fla. The website further surmises that the model could well debut this weekend at the SoCal LX Club Spring Fest 14 in Pomona, Calif., an annual gathering of Mopar fanatics. That would explain the flashy wrap graphics and our suspicions that this isn't a test car; why else would Dodge so clearly advertise the car's SRT lineage? Although both models would get specialized suspension tuning, it's believed that the engines and outputs will remain — a 485-horsepower, 6.4-liter V8 in the R/T Scat Pack and the 6.2-liter V8 making 717 hp for the SRT Hellcat. Both will also reportedly get the same 20-by-11-inch Pirelli performance tires as are found on the Challenger Widebody. They're wrapped around five-spoke blacked-out aluminum wheels, accented with red brake calipers. It appears we'll know more about this curiosity soon.
