2020 Dodge Challenger SRT Super Stock is as close as you can get to a new Demon

Although the Dodge Demon was an exclusive, one-year-only muscle car, Dodge has found ways of getting bits of that car to more people. First there was the Hellcat Redeye, that got a detuned version of the Demon engine, down from 840 horsepower to 797. Now there's the 2020 Dodge Challenger SRT Super Stock. It starts with the Hellcat Redeye, but adds a bit of horsepower, and drag race-specific tires and suspension tuning to get one step closer to the monster Demon. The engine is basically the same supercharged 6.2-liter Hemi V8 as the Redeye, but with a new engine calibration that bumps up horsepower by 10 to 807, though torque stays the same at 707 pound-feet. It's coupled to the same eight-speed automatic as the Hellcat Redeye, but it has also been retuned to shift 100 rpm later at 6,400 rather than 6,300 to squeeze as much out of each gear as possible. The rear differential is a limited-slip unit and comes standard with a 3.09:1 gear ratio, which is optional on regular Hellcat Redeyes. The Super Stock also gets revised chassis components. Instead of the regular Hellcat Brembo six-piston brakes up front, it gets lighter four-piston Brembo calipers with slightly smaller rotors, all in the name of going faster at the drag strip. The suspension has been retuned to shift weight to the rear wheels and improve traction at launch. In Track mode, the suspension switches to fully firm rebound and compression at the rear, and firm compression and soft rebound at the front to help facilitate the weight transfer. It stays in this mode as long as full throttle is applied, and reverts to the standard Track settings when lifting off the throttle. The final piece of the drag racing puzzle are the wheels and tires. The regular Redeye's huge wheels and low profile tires are gone in favor of wheels that are just 18 inches in diameter. They're fitted with Nitto NT05R drag radials, the same make and model as on the Demon, at each corner for maximum traction at the strip. These are also the only indicators that you have a Super Stock. All the other badging is the same as the Hellcat Redeye, so only those in the know will recognize a Super Stock model. The final results of these drag-racing enhancements are impressive. Dodge claims a 0-60 time of 3.25 seconds, and a quarter-mile time of 10.5 seconds. Apparently it will finish three car lengths ahead of a regular Redeye at the drag strip. Top speed is less formidable at 168 mph, but that's a limit of the drag tires.

Dodge Demon's A/C helps its supercharged Hemi make more power

Staying cool is one important key to performance. Simply, more air means more power, and cool, dense air is better than hot air. While forced induction might help make copious amounts of horsepower, turbos and superchargers produce heat. Intercoolers help, but the new Dodge Demon and its supercharged Hemi need a bit of an extra boost. In Drag Mode, the Demon's engine commandeers the car's air conditioning system to help chill things out. The Demon will have the first production application of a liquid-to-air charge air cooler chiller system. Literally, the car's air conditioning system is used to cool the air going into the engine, dropping temps by up to 45 degrees Fahrenheit. Dodge claims the system helps achieve "temperatures previously unattainable by pressure-charged street-legal production vehicles." As cool as this may sound, the technology isn't new. Ford had a prototype system in the early 2000s called SuperCooler, though that system never made it to production. While the Demon's system doesn't have a super cool name like the one from Ford, the pair essentially work in the same way. In theory, it should have the same effect as a bottle of nitrous. According to Autoweek, Ford's system bumped up the output of the F-150 Lightning by about 50 horsepower. Turns out that air conditioning isn't always a huge power suck. Related Video:

Mopar unveils Dodge Challenger Drag Pak [w/video]

Dodge is going drag racing, and it's doing it with an all-new version of the Challenger for NHRA's Sportsman class. FCA's Mopar parts and performance arm announced the new Challenger Drag Pak Friday, showing off a version with a 354-cubic-inch (that's a 5.8-liter, by the way), supercharged V8 and a 426-ci (7.0-liter), naturally aspirated V8 – both Hemis, of course – that can get the big coupes through the quarter-mile in "the eight-second range." While the two engines deliver similar performance, at their base, they're quite a bit different. The supercharged model uses a cast-iron block, while the 426 has aluminum for both the block and head. That said, both models get customized engine calibrations, and are mated to unique, race-spec automatic transmissions. But drag racing is about far more than just outright power. Mopar significantly updated the four-link rear suspension, adding a four-inch rear axle from Strange Engineering, along with an aluminum, nine-inch third member, while the rear-axle housing has been strengthened in general. Both the rear shocks and front struts can be adjusted for rebound and compression, too. Lightweight 15-inch wheels, meanwhile, are shod in super-sticky Hoosier drag radials, with nine inches of tread in back and 4.5 inches in front. The new Challenger Drag Pak should run the quarter-mile in "the eight-second range." In the cabin, there's an NHRA-spec roll cage, a Racepak gauge cluster, and a handsome pair of Sparco racing seats. Outside, supercharged models get blue decals, while naturally aspirated varieties get black stickers, although there's more to the new Challenger dragster's exterior than just its decals. Mopar tweaked the big-scoop hood, promising it's easier to get up to check on the engine, and the designers also added trailer tie-down straps in both the front and rear. While the dragster was the big news today, Mopar officials also announced the two enhanced Scat Pack kits for both the Dodge Charger and Challenger R/T. The 5.7-liter Hemi models gain an extra 56 horsepower and 30 pound-feet of torque in the Scat Pack 2 thanks to a new cam, valve springs, pushrods, and gaskets. The Scat Pack 3, meanwhile, adds 75 hp and 44 lb-ft, on top of the gains from the lower packages. That should be perfect for drivers who wish to snort in the face of their SRT 392-driving friends. The third stage adds a ported cylinder heads, as well as high-flow manifolds and catalysts.
