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.

Chrysler readying 20 Moparized vehicles for SEMA

The Las Vegas Convention Center has plenty of space for aftermarket companies and automakers to show off their wares, and it looks like Chrysler is taking advantage of the spacious floor plan. At next month's SEMA Show, Chrysler will have a full 20 cars from its six brands decked out with Mopar gear.
As a hint of what is to come, Chrysler released a handful of teaser sketches showing glimpses of modified Jeep Cherokee, Ram 1500, Fiat 500L and Chrysler 300 concept vehicles. The automaker will also use the venue to show off a new line of Jeep Performance Parts offered by the all-new Mopar Off-Road Division. In addition to the images, Chrysler also issued a brief press release - posted below - breaking down some of the "industry-first features" that Mopar has offered in recent years.

Dodge adds fire-breathing Durango SRT for 2018

The playbook for Dodge right now is pretty simple. Wring as much power out of as many things as humanly possible. Now comes the 2018 Dodge Durango SRT. Packing 475 horsepower and 470 pound-feet of torque, this seven-seat school bus will scoot to 60 miles per hour in just 4.4 seconds. Since the latest Durango launched for 2014, Dodge has unabashedly called it a three-row Charger. This beefy SUV makes that aggressive claim even more legit. "It does all the things we want a performance car to do," says Mark Trostle, head of performance, passenger, and utility vehicle exterior design. "It really is our three-row Charger." The 6.4-liter (392 cubic inches) Hemi V8 is considerably stronger than the already-potent 5.7-liter Hemi V8, which is rated at 360 hp and 390 lb-ft in the most powerful Durango available now. The SRT powertrain includes the TorqueFlight eight-speed automatic transmission used in the lesser Durango models (and many other FCA US vehicles), though it's calibrated specifically to the sportier demeanor of the SRT model. A similarly retuned full-time all-wheel-drive system rounds out the powertrain. Despite the fact this is a hot-rod SUV, it can still tow 8,600 pounds with a trailer, 1,200 pounds more than the most capable 2017 Durango (the rear-wheel 5.7-liter variant). View 9 Photos The Durango SRT is an obvious move for Dodge. The Jeep Grand Cherokee, which is built on the same platform in the same factory in Detroit, already has an SRT model. With rumors of a Hellcat-powered Grand Cherokee swirling and another Demonic Challenger on the way, the Durango was overdue for an engine upgrade. "When we launched the Durango in 2014, this is the one we really wanted," says Tim Kuniskis, head of FCA US' passenger car brands. There's no doubt this is an enthusiast-oriented SUV. Dodge even went to the trouble of certifying the Durango SRT's 12.9-second quarter-mile time with the NHRA and tested it a Virginia International Raceway. Buy a Durango SRT, and you get a full day at the Bob Bondurant School of High Performance Driving. When's the last time anyone did all of that with a three-row ute? It certainly looks the part. The hood bulges with new air-ducts to help keep the big Hemi chilled appropriately. There's a new front fascia with more air vents and LED fog lamps. Plus, the grille takes on a menacing new glare with a mesh pattern, and the body gets wider wheel flares. Click through the gallery, it really does look like a Charger from some angles.
