Dodge Demon makes so much torque, it needs stronger driveline parts

Torque is a lovely thing, a sweet and wonderful force that twists and pulls and can help propel a two-ton metal box forward at comical speeds. Torque is also fickle and will bend and break those same metal parts without a second thought, which is why the new Dodge Demon is compensating for its increased torque with some new re-engineered and reinforced parts. And there's software intended to combat wheel hop, which one of the most dramatic ways torque can break stuff. Week 8's video, "Race-hardened Parts," gives a hint towards what all these new parts can do. While we still don't know how much torque the Demon will throw out, we do know it's enough to warrant an upgraded prop shaft, half shafts, and a differential housing. The Challenger Hellcat, which is the basis for the Demon, makes 650 pound-feet of torque already. The new parts will go a long way toward making sure the work from the Demon's engine is properly translated into motion by those Nitto drag radials. The new prop shaft uses high-strength steel, heat-treated stub-shafts, and increases the tube thickness by 20 percent for a 15 percent increase in torque capacity. Additionally, Dodge says the upgraded differential housing allows for a 30 percent increase in torque capacity by using heat-treated A383 aluminum alloy and a higher strength shot-peened gear set. The 41-spline half shafts that deliver 20 percent increased torque capacity through the use of high-strength low alloy steel and 8-ball joints. In addition to the hardware, the Launch Assist software has been tuned to help alleviate wheel hop. Dodge says the Demon is the first factory production car that uses wheel speed sensors to detect hop and momentarily cut torque to compensate. This means a driver can keep their foot planted on the floor while the computer sorts out the traction. Previously, the best solution was to back off the throttle to manually cut the load. Finally, the Dodge Demon will offer a four-point harness mounting bar as an optional accessory. The part will be supplied by Speedlogix and fits in place of the deleted rear seat. Customers can install the bar without having to hack apart their cars to find a proper mounting point.

Rare Dodge Shelby Dakota is a very '80s sport truck

The late-great Carroll Shelby built an incredibly successful career of making all sorts of cars faster, more often than not, with a bigger or more potent engine under the hood. The icons are well known—legends like the Shelby Cobra, GT350 Mustang, and the big GT500. But by the 1980s, Shelby was plying his trade over at Chrysler, at the behest of chairman Lee Iacocca, churning out special editions like the Dodge Shelby Charger, zippy CSX, rorty GLHS, and this—the 1989 Shelby Dakota muscle truck. 1,500 of these racy pickups were built for just one year and a whole two-and-a-half decades later they still turn heads. This one especially. The spotless pickup recently turned up for sale online , and its odometer reads a claimed 25,307 miles. So what makes these rarified work trucks special? As with most Shelbys, it starts under the hood. Up until 1989, the standard Dodge Dakota pickups were offered in only four-cylinder and V6 variants. But Dodge (and Shelby) wanted more, so the larger 5.2-liter Magnum V8 from Dodge's full-size pickup was shoehorned into the midsize Dakota, albeit not effortlessly. To fit, Dodge had to swap the V8's belt-driven fan for an electric unit mounted in front of the radiator. That did the trick, as well as earned the V8 a few extra ponies, pushing the special Dakota up to 175 horsepower and 270 lb.-ft. of torque. That performance may sound paltry by today's standards, but in 1989 it was seen as quite sporty, and netted a zero to 60 mph dash in 8.5 seconds. A four-speed automatic with lockup torque converter transmitted that power to the rear wheels. Additional Shelby performance goodies included a limited-slip differential, transmission cooler, along with a host of eye-catching body mods, including a unique air dam and bumpers, Shelby floor mats, monogramed seats and door panels, a "CS" steering wheel, 15-spoke hollow alloy wheels, and shouty body graphics. While the Shelby Dakota didn't return for 1990, its V8 legacy did continue, and in 1991 the 5.2-liter eight-cylinder became an option on new Dakotas. Of the 1,500 Shelby Dakota pickups built, 860 were dressed in red while a rarer 640 came adorned in Bright White. This '89 is said to be #245 of those white trucks, sold new to its original (and sole) owner in Mechanicsburg, Pennsylvania, for $15,985 (the Shelby package cost $3,933 in its day). Currently, it's demanding bids north of $10,000 for its low-mileage originality. Related Video: This content is hosted by a third party.

Plymouth Rapid Transit System muscle car concepts going to auction

Over the past decade, Chrysler has built a reputation for amazing custom concept cars based on production vehicles for the SEMA Show and the Easter Jeep Safari. But the company's customization tradition has much deeper roots that include this collection of muscle car concepts headed for Mecum's Indianapolis auction this May. The collection includes three Plymouths that were featured in the traveling display called the Plymouth Rapid Transit System, and a Dodge that appeared at the 1969 Chicago Auto Show. The possible crown jewel of these cars is the 1971 Plymouth Road Runner, and that's simply because the car is completely unrestored with just 1,300 miles on the odometer. Apparently the owner of the shop that built the car for Chrysler got it back after the Rapid Transit System tour ended and took care of it until he later sold it to the late Steven Juliano, whose estate is now selling this collection of cars. Like all of these cars, modifications were mainly visual, but they were extensive. A custom nose and headlight lenses were fitted that added six inches of length, according to Mecum. The car's bumpers were removed completely, as were the external door handles. Recessed hood scoops were added to the hood, and the trunk lid was lowered by four inches to create a rear wing. The taillights were given red, yellow and green lenses like traffic lights. But the best additions were molded Road Runner head marker lights. The interior is mostly unchanged, and the engine is a stock 383-cubic-inch V8 with an automatic transmission. It also has power steering and brakes and the Plymouth Road Runner horn, which makes a "Beep! Beep!" sound like the cartoon the car is named after. 1970 Plymouth Duster View 12 Photos Then there's the 1970 Plymouth Duster in the collection with arguably the best paint scheme. It's bright green with groovy "DUSTER" lettering on the hood and various contrasting panels. It's actually the second scheme the car used, as according to Mecum, the car was built for the 1970 tour and then redesigned for the 1971 tour. The paint is matched with color-coordinated wheels and blue and green floral pattern floor mats. There are unique body changes, too, such as the custom headlight housings, functional brake air ducts up front, fake extractor vents above the rear window, racing-style fuel cap and rectangular exhaust. Mechanically, it has a stock 275-horsepower 340-cubic inch V8 and four-speed manual transmission.
