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.

Junkyard Gem: 1991 Dodge Stealth R/T

Chrysler's relationship with Mitsubishi goes back to the early 1970s, when the first Mitsubishi Colt Galants arrived from Japan with Dodge Colt badging. Plenty of Mitsubishi-built Arrows and Ram 50s and Challengers followed, and the joint Chrysler-Mitsubishi plant in Illinois began building cars in 1988. By the 1990s, you could find Mitsubishi DNA throughout the American Chrysler family, and the Mitsubishi GTO was brought over to become the Dodge Stealth starting in 1991. Here's one of those first-year Stealths, now residing in a Colorado self-service boneyard. Four grades of Stealth were available here in 1991, with the R/T Turbo AWD at the very pinnacle. This car, a regular R/T, is one step down from that model but still a pretty quick machine for its time. MSRP was $25,155, or about $55,370 in 2022 dollars. The R/T got this naturally-aspirated DOHC 6G72 engine, displacing 3.0 liters and making 222 horsepower. If you got the turbocharged version in the R/T Turbo AWD (or the Mitsubishi 3000GT VR-4), power went up to 300 horses. The 3000GT (as the GTO was known here) was mechanically identical to this car but had slightly different styling. The GTO/3000GT/Stealth replaced the Mitsubishi Starion and its Chrysler/Dodge Conquest siblings, which were sold here from the 1983 through 1989 model years. The Starion was a rear-wheel-drive machine that competed for sales against the Toyota Supra and Nissan Z, while the Mitsubishi GTO was available with either front- or all-wheel-drive. As illustrated by this photo of the rear suspension, this car is a front-wheel-drive version. Americans loved automatic transmissions 30 years ago, nearly as much as we love them today, but this car has a proper five-on-the-floor manual. If you wanted the optional four-speed automatic, it cost 813 bucks ($1,790 today). The Stealth R/T AWD had a mandatory five-speed manual transmission. This car has been hit hard by junkyard shoppers and the ravages of time, but it was fairly luxurious when new. Air conditioning was standard equipment on the R/T, though not on the lesser Stealths. This car came close to 150,000 total miles, but fell a bit short of that milestone. The final year for the Dodge Stealth was 1996, though the Mitsubishi 3000GT remained available here through 1999. The Mitsubishi GTO held on through 2000 in its homeland. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Outhandles the Lotus Esprit!

Dodge Durango poised for SRT's devilish power-up

Does the world need a 707-horsepower Dodge Durango Hellcat? It looks like it's a possibility, according to recent spy shots of a suspicious test mule. But it could also be a Durango powered up with the FCA US 6.4-liter V8 that makes 475 hp. Spy shooters report that the mule captured here sounds like the Hellcat-powered Dodge Chargers and Challengers. Hidden design cues like the fascia suggest this Durango has truly devilish power. There's also a bulging hood with an air intake under the camouflage. So it could be a Durango Hellcat. It's also possible Dodge is dropping the 6.4-liter V8 used in the Grand Cherokee SRT under the hood of the Durango. Engine sharing makes sense, since both FCA SUVs are based on the same platform and built at the same factory in Michigan, though the Durango is longer to accommodate a third row. It is also more logical Dodge would add the 475-hp mill to the Durango's lineup first before going all the way to the 6.2-liter 707-hp Hellcat engine. The most powerful current Durango has a 360-hp 5.7-liter Hemi V8. We expect the Durango will get a refresh for 2018.
