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.

2019 Dodge Challenger SRT Hellcat Redeye is the Demon spawn

The Demon has passed from us, but the Demon's spawn are here, so please allow them to introduce themselves. A new demi-Demon trim level has been anointed as the 2019 Dodge Challenger SRT Hellcat Redeye. Plus there's an updated Challenger SRT Hellcat and new Challenger R/T Scat Pack Widebody. Like with the Charger introduced this morning, they have inherited some of the best parts from the Demon. The Hellcat Redeye is possessed by the Demon's howling supercharged 6.2-liter Hemi, making 797 horsepower and 707 pound-feet of torque. Dodge proclaims it the "most powerful production V8" and "quickest production muscle car," with a 0-60 time of 3.4 seconds and quarter-mile time of 10.8 seconds at 131 mph. Top speed: 203 mph. Dodge can claim these superlatives, of course, because the 840-horsepower Demon's limited production run has ended. The Hellcat Redeye's Hemi is paired with an eight-speed automatic. Dodge says the powerplant gets 25 major component upgrades, including a larger supercharger (2.7 liters, up from 2.4) with higher boost pressure (14.5 psi, up from 11.6), strengthened connecting rods, pistons and valve train, high-capacity fuel injection system and improved lubrication. It gets a second fuel pump and a higher redline of 6,500 rpm. Theoretically, if you were someplace where you could operate at full throttle without letting up, Dodge says the Hemi would drain the fuel tank in under 11 minutes. Yet the car gets a 22 mpg highway rating from the EPA. View 30 Photos It also has the Torque Reserve system that starts building boost before launching, as well as the air conditioned intercooler to provide extra cool intake air. Both of these were features in the Demon. Furthermore, if the standard 2.62:1 final ratio isn't quick enough for you, Dodge offers a 3.09:1 rear axle. The Challenger SRT Hellcat Redeye also comes with the Demon and Hellcat Widebody's fat fender flares. It's an unsurprising inclusion, since you'll want as much tire as possible for all that power. Now, a mere clear-eyed Challenger SRT Hellcat gets a 10-horse boost for 2019 to 717 horsepower, and a smidge more torque at 656 pound feet. A six-speed manual transmission is standard, and an eight-speed automatic is an option. Both Hellcat models get the new dual-snorkel hood we've seen in spy shots. It's meant to evoke 1970s Dodge muscle cars. Dodge says the airflow from the hood alone reduces engine temperature by 4 degrees Fahrenheit.

Hennessey Dodge Demon sets hellishly fast quarter-mile time

The Dodge Demon doesn't strike us as a muscle car much in need of a performance makeover. After all, this 840-horsepower MoPar machine's voracious quest for straight-line speed means it trims weight by jettisoning everything from a front passenger seat and rear seat, to its stereo and all carpeting in the trunk. The folks at Hennessey apparently think that's not nearly extreme enough. So, the Texas-based tuning outfit has turned the Demon into a 1,035-horsepower mega beast that runs a quarter-mile in 9.14 seconds at 152 mph. That's fast, really fast. In fact, the HPE1000 is now the world's fastest Dodge Demon, having set its record-setting pace at Lonestar Motorsports Park on May 8. "The 2018 Demon is a street-legal rocket from Dodge, but we wanted to take the car's impressive track times to an industry leading level." said president and company founder, John Hennessey. For comparison, the stock Dodge Demon is credited with running the quarter-mile in 9.65 seconds at 140 mph. The main HPE1000 modification involves replacing the stock 2.7-liter supercharger with one that's a staggering 4.5-liters in capacity. Also included in the Hennessey toy-chest are stainless steel long tube headers, a high-flow air induction system, upgraded throttle body, upgraded fuel pump and fuel injectors, along with custom engine management calibration. When all is said and done, the HPE1000 Dodge Demon delivers a total of 1,035 horsepower at 6,500 rpm and 948 pound-feet of torque at 4,200 rpm. While the standard Demon accelerates from 0-60 mph in only 2.3 seconds, the Hennessey variant trims this down to only 1.9 seconds. That's quick enough to make a Bugatti Chiron blush. Hennessey hasn't stated what all this will cost, though the company did say production of these devilishly fast Demons will be limited to only 50 examples. Customers also receive a 1-year/12,000-mile warranty, which seems a nice touch for a car that's downright scary with its performance specs.
