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.

Are supercars becoming less special?

There's little doubt that we are currently enjoying the golden age of automotive performance. Dozens of different models on sale today make over 500 horsepower, and seven boast output in excess of 700 hp. Not long ago, that kind of capability was exclusive to supercars – vehicles whose rarity, performance focus, and requisite expense made them aspirational objects of desire to us mortals. But more than that, supercars have historically offered a unique driving experience, one which was bespoke to a particular model and could not be replicated elsewhere. But in recent years, even the low-volume players have been forced to find the efficiencies and economies of scale that formerly hadn't been a concern for them, and in turn the concept of the supercar as a unique entity unto itself is fading fast. The blame doesn't fall on one particular manufacturer nor a specific production technique. Instead, it's a confluence of different factors that are chipping away at the distinction of these vehicles. It's not all bad news – Lamborghini's platform sharing with Audi for the Gallardo and the R8 yielded a raging bull that was more reliable and easier to live with on a day-to-day basis, and as a result it went on to become the best-selling Lambo in the company's history. But it also came at the cost of some of the Italian's exclusivity when eerily familiar sights and sounds suddenly became available wearing an Audi badge. Even low-volume players have been forced to find economies of scale. Much of this comes out of necessity, of course. Aston Martin's recent deal with Mercedes-AMG points toward German hardware going under the hood and into the cabin of the upcoming DB11, and it's safe to assume that this was not a decision made lightly by the Brits, as the brand has built a reputation for the bespoke craftsmanship of its vehicles. There's little doubt that the DB11 will be a fine automobile, but the move does jeopardize some of the characteristic "specialness" that Astons are known for. Yet the world is certainly better off with new Aston Martins spliced with DNA from Mercedes-AMG rather than no new Astons at all, and the costs of developing cutting-edge drivetrains and user interfaces is a burden that's becoming increasingly difficult for smaller manufacturers to bear. Even Ferrari is poised to make some dramatic changes in the way it designs cars.

That thing got a Hemi? Mopar engine kits make it easier to say yes

Thanks to a new kit from Mopar, classic car owners will have an easier time dropping Hemis into their muscle cars. The kit works with Mopar's 345 and 392 Hemi engines (5.7 and 6.4 liters respectively) and with cars built before 1975. The kit will run $1,795 and has everything needed to get one of the above engines running. The parts include a power distribution system, engine computer, engine and chassis wiring harnesses, O2 and intake air temperature sensors, ground wiring and a gas pedal. The kit is also designed to work with a manual transmission, but Mopar says a transmission such as the Torqueflite 727 and 904 can be made to work with the system. As for examples of the kit in action, take a look at the Jeep CJ66 and Dodge Challenger Shakedown that Mopar revealed this week at the SEMA show. Mopar also offers a few other parts to help complete the project, including various oil pans to clear subframes, a set of headers, and accessory drives for power steering and air conditioning. All of these parts are extra cost though. You'll also need an engine, and the 345 starts at $6,070, and the 392 runs $9,335. However, if you happen to already have one from 2014 or newer, that will work, too. Muscle car fans are getting more choices for their engine conversions. Chevrolet Performance already sells crate engines with "Connect and Cruise" kits to get its engines working in classic cars. The General also offers it with more engines. However, for people who want to keep a Mopar engine in their classic Chrysler, Dodge, Plymouth, or Jeep, this is a cool new option.
