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.

Indications of 825 hp and emissions issues for Hellcat called 'speculation' by Chrysler

The 2015 Dodge Challenger SRT Hellcat is probably one of the hottest cars of the moment mostly because of its insane, 707-horsepower supercharged V8. However, there are conflicting reports coming out that the powerplant might be having problems with its emissions compliance and may be capable of even more power.
Jalopnik says that an unnamed source within Fiat Chrysler Automobiles told it that the Hellcat was having problems meeting emissions standards at its 707-horsepower tune. The person claimed that the automaker has been testing the V8 with different types of sensors, possibly to make it a bit cleaner in the future. Autoblog spoke to SRT spokesperson Dan Reid, and he said about the claimed poor emissions, "It's totally speculation."
The source also claimed that the Hellcat had been dynoed at a monumental 825 horsepower, internally. Based on the other rumor, though, it's hard to imagine the engine being emissions compliant like that. Autoblog also asked Reid about this speculation about more power and was told, "They are totally speculating about that."

Widebody Challenger Hellcat spotted with no camouflage

Well this is a mightily mysterious muscle car. One of our photographers caught this Dodge Challenger out testing without any camouflage. At first glance it looks like an SRT Demon, since it has the same widebody flares and front spoiler of the hellacious Challenger. However, the hood is from a garden-variety Hellcat (as if such a thing existed...), the rear spoiler has an SRT Hellcat badge, and the wheels don't come from the kitty or the Hellspawn. We have two theories as to what this SRT mishmash may be. Our first is that this is perhaps a next-generation Hellcat that takes advantage of some of the Demon's developments. It could have a more potent engine under the hood, perhaps with the extra fuel pumps and air-conditioned intercooler, along with the Demon's beefier driveline. It would be a way to keep the Hellcat relevant, and a way for people who might miss out on the one-year-only Demon to get the next closest thing. Our other theory is that this is an all-wheel-drive Hellcat. The wide fender flares and chin spoiler appeared on an all-wheel-drive Challenger concept before they made their way to the Demon. And with the introduction of the Grand Cherokee Trackhawk, we know that Mopar has an all-wheel-drive system that can handle the grunt of the 707-horsepower Hellcat mill. If an all-wheel-drive Hellcat is in the cards, it would be another way to keep the Hellcat line fresh without too much investment, and would be a treat for fans of the old all-wheel-drive concept. It would also probably be a great seller here in snowy Michigan. Oh, and it would certainly post some amazing 0-30 acceleration times. Related Video:
