This 3D-Printed Part Helps Ken Block’s Hoonitruck Make 900 Tire-Destroying Horsepower

Of all the vehicles featured in Ken Block's Gymkhana 10, his 900-horsepower Hoonitruck is arguably the most high-tech. Alongside all the complex electronics required to run the high-powered engine and all-wheel-drive system, it features the single largest 3D printed metal component ever fitted to a wheeled vehicle.

In order to make the 900-plus horsepower necessary for all that tire smoke, a twin-turbo, 3.5-liter V-6 of the same spec as that found in the Ford GT supercar was dropped into the 1977 F-150, but its base power of 647 horsepower wasn't quite enough to do the job. The solution—more boost—is simple on paper, but required an intake manifold capable of withstanding the greater pressures associated with cramming extra air into the engine.

Ford Performance's answer to the quandary was to contract the Digital Additive Production Institute of German technical college RWTH Aachen, which advised the automaker on how to turn its conceptual manifold into a reality using additive manufacturing—known better as 3D printing. Though it takes time, additive manufacturing is typically less wasteful than machining and capable of more intricacy than casting.

By gradually adding aluminum over a period of five days, layer by tiny layer, Ford built up the complex, six-kilogram (13.2-pound) part, which juts up from the Hoonitruck's low hood, the crown jewel of the engine.

"I think Ford did an exceptional job," Block said of the manifold. "This is my favorite part of the Hoonitruck. You could not have made it any other way."

"We are fortunate to have access to incredible technology, but this was one project that pushed us—and our computing power—to the absolute limit," added Advanced Materials and Processes Engineer Raphael Koch, from Ford of Europe. "The manifold has a complex web?like structure that couldn't be made using traditional manufacturing methods. We ended up dissolving the support systems in acid."

Automakers and aftermarket suppliers alike are turning to 3D printing for more parts as the technology matures. General Motors is readying a handful of cutting-edge components manufactured using 3D printing for use in low-volume vehicle applications, while wheel manufacturer HRE has demonstrated that additive manufacturing can be used to create elaborately designed titanium wheels for use on exotic cars. At this rate, it may not be long before 3D printed parts appear in your next commuter.

Mopar Lovers Rejoice: Sublime Green Is Back for 2019 Dodge Challenger and Charger

Dodge is a big fan of "If it ain't broke, don't fix it," meaning that it's constantly finding ways to market its Charger and the Challenger muscle cars despite the duo being more than a decade old in their current forms. As a result, a classic Mopar paint color has been brought back—a bright hue called Sublime and it makes these Dodge muscle cars even more in-your-face, and lovable.

A Dodge spokesperson confirmed to The Drive that Sublime will be available across the entire model lineup of cars, from the budget-friendly V-6 models to the fire-breathing Hellcats.

“Our Dodge//SRT muscle cars give our customers what they want, an incredibly wide variety of performance models and high-impact color options," said Steve Beahm, head of passenger car brands for FCA North America in a statement. "Whether it's Sublime paint, all-wheel-drive capability, or 797 horsepower, Charger and Challenger stand out.”

Sublime was available on the Challenger as recently as 2015, but it hasn’t been seen on the Charger sedan since the 2007 Daytona model, meaning it’s the first time the color is available on the current generation of the car. Sublime was first introduced in 1970 when the brand brought the eye-popping color to most of its lineup.

You can order your Sublime 2019 Dodge muscle car starting this Spring. To get a peek at what these cars look like in person in this high-impact color, they’ll be making their live debut at the Chicago Auto Show next week.

Set of Bugatti Veyron Wheels and Tires Pop Up on eBay for $100,000

A quartet of wheels and tires for a Bugatti Veyron has surfaced on eBay for the price of $100,000...with free shipping.

The set is sold by a Fort Lauderdale, Florida-based eBay user by the name of genuinewheel, who has a reputable seller feedback rating. They claim that waiting for replacement wheels from Bugatti can take up to a year and cost $150,000, as opposed to buying their set and having them delivered in days.

Closeup photos of the wheels show Bugatti's trademark "EB" stamp, and "Made in Italy" markings. Though these wheels would be expensive to counterfeit, the markings do not inherently rule out the possibility of these being knockoffs.

Better evidence backing the seller's claim that these are the Real McCoy can be found on the sidewalls of the tires, where manufacturing information on the tires reveals their origin. Moldings reveal two of the tires to be 365 millimeters wide, or exactly that of the Veyron's rear wheels. There are also "Pax" readings on the sidewall, which designates a type of run-flat tire manufactured by Michelin for a small selection of vehicles. The Veyron was one of these vehicles, and it's the only one to feature 365 millimeter-wide tires (on the rear axle).

If you are a Veyron owner in need of a set of tires, or spare wheels, hold your 987 horses—these tires aren't necessarily in peak condition. Though the seller says they have 85 percent tread left, and the photos suggest this to be true, there's a troubling string of numbers on the side. They say "2513," and are shorthand for the tires' date of production, or the 25th week of 2013.

Old tires and high-performance cars are a bad mix; the combination killed Paul Walker. Tires more than five years old are unsafe for any kind of fast driving, which is the Veyron's raison d'être. Consider instead buying a set of Veyron wheels sans tires, which this eBay user, coincidentally, is also selling. Pick up a fresher set of tires separately so you don't make the evening news.

This Hot Rod Snowblower Is Powered by a Harley-Davidson V-Twin Engine

A wimpy little single-cylinder snowblower might be good enough for your measly little driveway, but when you want to get serious about snow removal, call the madmen at the Sisufab motorcycle shop in West Fargo, North Dakota. These guys felt like taking their dirt bikes out on a frozen lake, but there was just one problem; there was too much snow covering the local watering hole. So, they did what any self-respecting Midwesterner would do and restored an old snowblower using a Harley-Davidson V-twin and slapped it on the front of an old Dodge Ram.

We went ice riding this weekend. Oddly, I didn't take any photos of motorcycles. •• #harleydavidsonsnowblower #sisufab #iceracing #snowster #sportsterofinstagram #sportster #harleydavidsons #jäärata #snowblower #snowthrower #servocity #truckmountedsnowblower

Many questions might be rushing to your mind upon seeing this beauty and we’ll do what we can to answer them. It all started with an old Mckee 720 seven-foot, two-stage snowblower originally designed to be mounted to a tractor. It wasn’t pretty when the guys at Sisufab picked it up, but they certainly gave it a new lease on life.

The top auger of the snowblower was ditched in the name of weight savings and some new bearings as well as a fresh coat of paint made it like new again. They needed a donor engine for this old unit and went with an Evo V-twin from a 2010 Harley-Davidson Sportster XL1200 that was involved in a fire. All it took to get the engine running again was replacing a few parts that were damaged by the blaze.

We needed a way to move snow for ice racing so @tuurdferguson85 and Ben with some help from myself spent some after hours time building this. I think it's the first @harleydavidson power, truck mounted snowblower. Powered by a 2010 XL1200 engine and a bunch of on the fly engineering. It works pretty well! Now time to slap a coat of paint on it and do some ice racing! •• #harleydavidsonsnowblower #sisufab #iceracing #icebike #jäärata #sisu #dodge #dodgeram #sportster #sportsterofinstagram #xl1200 #nightster #snowster #radiocontrolled #becauseroadkill @dodgeofficial

Once it was all put together, they needed something to push their hot rod snowblower. They went with a rather humble farm truck; a 1999 Dodge Ram 2500 4x4 single cab. Perhaps the coolest thing about the whole setup is the RC system that allows you to control the throttle, clutch, and chute of the snowblower from inside the truck.

Harley-Davidson keeps horsepower figures a secret, but the Evo 1200 engine is often estimated to make somewhere between 60-70 hp. For reference, the snowblower in your garage probably makes less than 10 hp, proving this as a pretty strong improvement over the typical Briggs and Stratton or Honda power unit.

While this may be a case of overengineering for a problem that many wouldn't consider an issue in the first place, we're all on board for a bit of redneck tomfoolery.
