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 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:

The Dodge Demon was developed under a cloud of smoke

The Dodge Demon needs no introduction. The car is so full of superlatives that most of it sounds unbelievable until you see and hear it in action. The car was revealed after months of teasers and cryptic messages, but the public weren't the only ones in the dark. From the start, the Demon's development was a closely guarded secret. There were even some within SRT that didn't know about the project. The people behind the car went through a lot of effort to keep it that way. At an event covering the finer details of the Demon's supercharged 6.2-liter V8, Dodge CEO Tim Kuniskis and SRT Powertrain Director Chris Cowland spoke about the smoke and mirrors used to hide the Demon's development. Work on the car progressed for nearly two years before it was made public, with just a small team having full access to the project. Numbers were altered. Secret meetings were held. SRT engineers worked nights and weekends while parts suppliers were given as little information as possible to move progress forward. Preliminary work on the Demon began in April of 2015, not long after the standard Hellcat hit the streets. The goal wasn't to create a faster Hellcat. Kuniskis said that would have been easy. They wanted a single-minded vehicle that could also be driven on the road. It's the same mindset that brought about the Dodge Viper ACR. Dodge wanted a car that could sell the brand to both enthusiasts and non-enthusiasts alike. 840 horsepower is going to raise anyone's eyebrows, including the Camry owner parked down the street. While preliminary work started in April, the final greenlight wasn't given until September. The project was originally going to revive the American Drag Racer, or ADR, name. When we saw the first hints of the Demon last fall, we labeled the spy photo above the Dodge Challenger ADR. It was set to have 10-percent more power and 20-percent more launch force than the already gut-punching Hellcat. It was also only going to have a quarter-mile time in the 10s, just slightly quicker than the Hellcat. Somewhere along the line, the team realized that the ADR wasn't enough. It was just going to be a Hellcat plus, and that wasn't exciting. The main goal was changed: 9s with light. Translated, that means a 9-second quarter mile with light under the tires (read: a wheelie). From that point forward, everything about the Demon's development, from power to suspension to weight, would be done in pursuit of that goal.
