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.

Chrysler recalling 67k trucks with manual transmissions

Earlier this month, Chrysler announced the recall of some 280,000 pickup trucks over concerns that their axles could seize up. Now the automaker has announced an entirely separate recall of another 66,819 trucks over the springs that could break in the clutch ignition interlock switch. The recall affects Dodge Ram 1500, 2500 and 3500 pickups, as well as the Dodge Dakota and Mitsubishi Raider. The issue is relevant only to those trucks fitted with manual transmissions, from the 2006 and 2007 model years and manufactured between July 1, 2005, and July 31, 2006. Since a broken spring could, according to statements issued by the National Highway Traffic Safety Administration and FCA US LLC (previously known as the Chrysler Group) prevent the vehicle from starting, or cause it to move unintentionally once the ignition kicks over, the automaker will begin notifying owners of the affected vehicles just before Valentine's Day to bring their trucks into their local dealers to have the clutch ignition interlock switch replaced. FCA emphasizes, however, that the unintended movement would only occur "in rare cases" and only "if recommended starting procedures are not followed." Only one such case is known to have occurred, but it did regrettably result in a fatality. Statement: Clutch Ignition Interlock Switch December 29, 2014 , Auburn Hills, Mich. - FCA US LLC is launching a voluntary global recall of an estimated 66,819 older-model pickup trucks equipped with manual transmissions. The Company will replace their clutch ignition interlock switches at no charge to customers. An investigation by FCA US engineers discovered switches in certain model-year 2006 and 2007 pickups may be equipped with spring wire that differs from wire used in previous switches. The alternate wire may break and, as a result, the vehicles may not start. In rare cases, a vehicle may – if recommended starting procedures are not followed – exhibit unintended movement when its ignition key is turned. The Company is aware of one fatality related to this campaign. It stemmed from the single known accident involving this population of vehicles. The recall covers certain Dodge Dakota, Dodge Ram 1500, 2500, 3500 and Mitsubishi Raider pickups. Switches with the alternate wire were not used in any vehicles produced before July of 2005, or after June of 2006. The Dakota and Raider are no longer in production.

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:
