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!"

GMC Syclone pickup returns via Special Vehicle Engineering

The original GMC Syclone was a 1991 mid-size Sonoma pickup turned muscle truck. Its heavily modified 4.3-liter V6 sported a turbocharger, intercooler, and modified internals, raising output to a Corvette-baiting 280 horsepower and 350 pound-feet of torque. The engine was paired with a four-speed automatic, rear-biased all-wheel drive, and four-wheel antilock brakes (the coming thing). With an all-black livery and a lowered ride height, the Syclone looked the business, and backed up those looks with a 0-to-60 time of 4.3 seconds and a 13.4-second quarter-mile, according to contemporary magazine testing. Given all the recent interest in high-performance pickups, it's amazing that GMC hasn't revived the Syclone. But where manufacturers leave an opening, the aftermarket steps in — in this case that's Specialty Vehicle Engineering, which as CNET reports is resurrecting the nameplate for a build of 100 new Syclones, based on the GMC Canyon, which will update the idea a lot more horsepower. The 2019 Syclone takes as its starting point the extended-cab version of the Canyon. The engine is again a V6, this time a 3.6-liter fitted with a supercharger and a custom cat-back exhaust system, upping output to 455 ponies from the stock 306. SVE's Syclone can be had with rear- or all-wheel drive, and it, too, features upgrades to the brakes and chassis. Six-piston front calipers are fitted in place of the standard four-piston units, and the slotted front rotors are upsized from 12.2 inches to 13.6. The suspension is lowered by two inches up front and five inches at the rear, with stiffer traction bars, bushings, dampers, and a heftier rear anti-roll bar. Unlike the original, the modern Syclone can be had in colors other than black — any of the standard Canyon hues are available — but the appearance is customized with rocker-panel extensions, body-color grille and rear bumper, and a composite hood insert. The interior gets embroidered logos and badges, including a numbered plaque on the dash. The price for the Syclone is $39,995 — that's for the package, on top of the cost of the truck. But at least ordering is easy: The Syclone package can be ordered through select GMC dealers.

2020 Harley-Davidson GMC Sierra brings the iconic brand to a new truck

The Harley-Davidson Ford F-150 rides alone no longer. Thanks to the Tuscany Motor Company, it now has a fellow truck associate to cruise with side-by-side on the open roads. Introducing the 2020 Harley-Davidson GMC Sierra, which will make its official debut at the 2020 Barrett-Jackson Scottsdale auction. For years, a Harley-Davidson special edition package has been associated with the Ford F-150 nameplate. Although Ford does not offer a direct option from the factory, Tuscany Motor Company answered the demand and now builds truck packages that carry the famous American motorcycle name. With the direction of Harley-Davidson, Tuscany creates interior and exterior customizations that reflect notable and iconic features of the bikes. This year is the first time Tuscany has ever offered a Harley-Davidson package on a GMC Sierra, and as expected, it's pretty similar to the one offered on the F-150. The package includes at least 60 exclusive parts, and the Sierra is available in Onxy Black, Summit White, or Satin Steel Metallic.  Setting the tone are Fatboy-inspired 22-inch milled aluminum wheels wrapped in chunky 35-inch all-terrain tires. As Tuscany is a division of Fox performance parts, the truck rides on a specially designed BDS suspension with tuned Fox shocks and lateral stability bars. The truck also has a redesigned front bumper and grille with an integrated LED light bar for off-roading, power running boards with rock guard trim and entry lights, color-matched Harley-Davidson-designed fender flares, custom front fender vents with the Harley logo, an induction-style hood, a redesigned rear bumper, and a tuned exhaust with billet tips. More badging, tailgate cladding, a windshield header, orange tow hooks, and a bed rug add extra pizzazz. Finally, for all the planes, drones, and aliens who are eyeing pickups from the sky, the tonneau cover is debossed with the Harley-Davidson logo.  Inside, the fan pack includes leather seating with orange diamond stitching, and piano black door panels, console, and trim. Harley-Davidson badging and branding is on the seats, on the center console, on the floor mats, the door sill inserts, the instrument gauges, and even the pedals.  If this is up your alley, and you're interested in buying, the Sierras, no matter the color, start at $94,995 before taxes and fees.
