Dodge Scat Pack for 5.7L Hemi V8 detailed, priced

Dodge revived the Scat Pack name back in November at the 2013 SEMA show. At the time, though, we were short of details on forthcoming upgrade packages, which were destined to add some oomph to the Challenger, Charger and Dart. We're still waiting to hear about the upgrades to the Dart's 2.4-liter four-pot, but Dodge has gone ahead and released the details on the upgrades to the 5.7-liter Hemi V8 in the Challenger and Charger R/T.
As we detailed in our original post, three different Scat Packs will be available that will allow customers to upgrade their cars without voiding the warranties. Starting with the $2,195 Stage 1 kit, owners will net an extra 18 horsepower and 18 pound-feet of torque thanks to a Mopar-branded cold-air intake, exhaust and ECU ref lash. Stage 1 is also the only package that could be installed outside of a Chrysler-authorized service center without voiding the warranty (a mechanically competent owner could even do it at home, we're told by Dodge). Stage 2 builds on the entry level Scat Pack, and adds performance camshaft kit, which boosts output over the stock 5.7 by up to 30 hp for $1,895. As with the Stage 1, the ECU is tweaked.
For those that want to go whole hog, they can add the Stage 3 for $4,995. The top-tier gets quite serious, adding CNC-ported cylinder heads, as well as high-flow headers and cats. Output over stock is 58 hp and 47 lb-ft of torque. Each kit comes with a pair of badges, just in case owners want a bit of visual flair.

Dodge Challenger Scat Pack adds power and noise, with a warranty

If you want to go fast, there's certainly nothing wrong with the Dodge Challenger SRT8. With 470 horsepower and 470 pound-feet of torque for 2014, there's certainly not much to complain about. But what if you want something more aftermarket in flavor? There's no shortage of options, but while turning to the tuner world will make your car plenty fast, that extra power won't just shred rear tires, it'll torch your warranty, as well. That's where Dodge's Scat Pack comes in.
With three stages of mods for both the 5.7 and 6.4-liter Hemi V8s Challenger (as well as the 5.7-liter Charger and, soon, the four-pot Dart), the Scat Pack cars give drivers all the power, aggression and noise of a heavily modded aftermarket car while maintaining the piece of mind provided by the Dodge warranty.
Power gets bumped up to 485 horsepower and 475 pound-feet of torque with the 6.4-liter Scat Pack, while the 5.7-liter can provide up to 58 hp and 47 lb-ft of torque to add to the stock engine's 375 horsepower and 410 pound-feet. It's the latter engine that can really get some work done, with upgrades ranging from the mundane - intake and exhaust - to the racy, like the ported heads and high-flow headers.

Dodge Challenger spied exercising supercharged Hellcat Hemi V8

One of the prime complaints against the Dodge Challenger is that, even in SRT8 guise, its 470 horsepower is responsible for hauling over 4,200 pounds of vehicle. For comparison, the 420 hp in the Ford Mustang GT only has to deal with 3,618 lbs. Things only get worse from there, as the higher-performance variants of both the Mustang and the Chevrolet Camaro are far more powerful than an SRT8 without adding on much heft.
So what is Chrysler to do? The correct answer is add a whole lot more grunt to its hefty two-door and even the odds. That's where the all-new Hellcat engine comes into play. We reported on this engine in May, and suggested that the Hellcat, a supercharged powerplant based on a 6.4-liter V8, would easily generate 500 to 570 hp and could likely arrive boasting more than 600 ponies.
Chrysler's ace in its sleeve has now been spied testing, with a number of Hellcat-equipped Challengers running the potent new engine both in more urbanized areas and under the sun of Death Valley. The hoods on these testers have been raised to accommodate the engine, and that camouflage over the fascias of these prototypes is there to hide a larger air intake. We also note what appears to be a new split grille under wraps. As for power output, our spies are now suggesting a Viper-equalling 640 hp from the Hellcat-equipped cars.
