Just try to grind these gears! Demon Gears, Torque Convertor Detailed

Demon Gears, Torque Convertor Detailed

The newest information on the 2018 Dodge Challenger SRT Demon was released this morning and this week, we learn about the rear gears and the torque convertor – both of which offer 18% better torque multiplication when compared to the Hellcat Challenger.

We learned a few weeks back that the 2018 Dodge Challenger Demon will wear Nitto NT05R drag radial tires which were designed specifically for this car, with a unique construction and composition from the NT05R tires already on sale for everyone else. These tires are stickier and wider than the tires on the Hellcat, measuring 12.6 inches wide and allowing the Demon twice the grip of the Hellcat.

Well, it seems that the traction of the Challenger Demon is so good that Dodge has gone ahead and engineered this new muscle car to send significantly more power to the rear wheels on launch with the addition of a new torque convertor and a new rear gearset.

Dodge hasn’t announced the stall RPM for this new torque convertor, but we know that this new component will yield 18% better torque multiplication compared to the unit in the Hellcat. Mind you, this doesn’t include any additional power from the Demon engine, but regardless of the output, the Demon transmission will multiply the torque output from the engine by 18% more than the Hellcat convertor.

Next, when the power moved through the driveshaft to the rear differential, it will come to the next unique feature of the 2018 Challenger Demon in the form of a new 3.09 gear set. This is 18% more aggressive than the 2.62 gears in the Hellcat, which leads to 18% more torque multiplication at the wheels.

In total, the new torque convertor and the 3.09 gears will offer more than 35% better torque multiplication on launch and when you launch the 2018 Dodge Challenger Demon with the drag radials, the tires will wrinkle up as displayed in the photo above before rocketing the car down the track.
In addition to the information on the gears and torque convertor and the image of the wrinkled up tires, we also get our newest Demon teaser video, which you can check out above.

The Air Grabber Returns on the 2018 Challenger Demon

The Air Grabber Returns on the 2018 Challenger Demon

Dodge rolled out 4 new teaser images, a new video and a handful of information on the 2018 Challenger SRT Demon today – stating that it will be powered by a supercharged Hemi which will be fed plenty of cool air by the new Air Grabber hood system.

As you can see in the images here, today’s teaser information focuses on the front end of the 2018 Dodge Challenger SRT Demon – with special interest being paid to the hood. The new Demon will have the largest hood scoop on any production car in America, measuring 45.2 square inches and spreading nearly the entire width of the hood. In addition to that big scoop, the Demon has Air Catcher headlights on both sides.

All of the air that is sucked in through this huge hood scoop heads through a channel in the underside of the Demon’s aluminum hood to a duct which fits tightly over the top of the new, larger air filter box, where it meets up with the air from the headlights. From there, the air is sucked into the supercharged Hemi, mixed with gasoline and turned into good old American horsepower.

This system is quite different from the Dodge Challenger SRT Hellcat, which has just a single Air Catcher headlight and smaller hood scoop which doesn’t feed the engine directly. This new, more elaborate air intake system is called the Air Grabber, and while it doesn’t function anything like the Air Grabber hood on the 1969 Plymouth Roadrunner, it serves the same purpose of drawing in tons of air to feed a Hemi V8.

The new Air Grabber system in the 2018 Challenger SRT Demon has far more potential for feeding fresh air into the engine bay, but it also helps feed much cooler air into the supercharged Hemi. In fact, when tested alongside the Hellcat, the Demon saw air intake temperatures which were 30 degrees cooler on a warm day. That is a serious reduction in engine air heat, which should help the Demon’s Hemi make even more power – we just don’t know how much power yet.

Finally, along with the four images shown here and the few bits of information, Dodge offered up the newest teaser video on IfYouKnowYouKnow.com, which offers a computer generated example of the air flow properties of the 2018 Challenger SRT Demon.

Dodge Challenger SRT Demon Comes with a Crate, Confirms RWD

The Demon Comes with a Crate, One Which Confirms RWD

Early this morning, the 4th 2018 Dodge Challenger SRT Demon teaser video went live on IfYouKnowYouKnow.com and with that new clip comes the most detailed press release on the Demon thus far.

The new press release opens with this statement, which clarifies the fact that the new Dodge Demon is a drag car, not a road race car, even with the wide tires on all four corners:

Twenty-two days into the pre-launch campaign, the general consensus seems to be that the Challenger SRT Demon is a single-seat, gutted-out, purpose-built drag car. But this week’s teaser video starts to bring the Challenger SRT Demon’s true mission more clearly into focus.

The Challenger SRT Demon provides a platform from which each customer can design their own ultimate “Street/Strip” muscle car. It’s not intended for a road course; rather, each customer can decide at the time of order, or once they own the car, or even on a moment’s notice that they want their car to favor street performance, drag strip performance or something in between.

The key is building in the capability and flexibility and then giving the customer access to the right gear for the job.

So there you have it – official word that the 2018 Dodge Challenger SRT Demon will be street legal and it will be a drag strip machine. When Dodge announced that the Demon has 18x11 lightweight wheels wrapped in Nitto NT05R drag radial tires on all four corners, some people speculated that it would be a road race car and when it was announced earlier this week that it wouldn’t have a passenger or rear seat, some believed that the Demon wouldn’t be street legal.

This week’s information corrects those erroneous rumors, but it leaves the question of why the Demon has four fat tires.

Well, that is where the Demon crate comes into play. The Demon-branded crate shown above seemingly comes with the new Dodge Challenger SRT Demon and in that crate are 18 items which “maximize the Challenger SRT Demon’s flexibility, exclusivity and future collectability”. This includes Direct Connection Demon Performance Parts and the Demon Track Pack System, neither of which have any explanation. The crate also includes Demon-branded track tools and matching Demon spare wheels, and in the new teaser video titled “Crate”, we see a guy unloading an impact gun, a torque wrench and a jack – presumably the swap to the skinny front wheels laying on the ground.

Provided that these wheels are indeed drag skinnies, there is most certainly no way that the Demon is all-wheel drive, as they wouldn’t build a drag car with AWD only to put skinny tires up front and remove the added grip of AWD. So, you get to the track, you use the Demon-branded tools to swap out the fat front wheels for the skinny front wheels and you go drag racing.

So now we have to wonder what the Direct Connection Demon Performance Parts and the Demon Track Pack System might be, but this teaser confirms that with the inclusion of skinny front Demon wheels, the 2018 Dodge Challenger SRT Demon is probably not all-wheel drive – while verifying that it is a drag car and not a road race car.
