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:

Hennessey's Dodge Challenger Hellcat cranks out 1,032 hp

Enthusiasts know the Dodge Challenger Hellcat produces 707 horsepower. It's one of the modern muscle-car era's iconic numbers. But for some, that's not enough. Enter Hennessey Performance. The Texas tuners loaded the Hellcat with a twin-turbocharger that works with Dodge's supercharger to boost output to 1,032 hp and 987 pound-feet of torque. Yes, that's an engine dyno rating, not at the rear wheels, but still! It's a little more complicated than a bolt-on booster. Called the HPE1000, the turbo kit has stainless steel headers and down pipes, billet aluminum compressor wheels, and a high-flow air system. There's also an an improved fuel pump, and the engine and chassis are specially calibrated. You also get numbered plaques signed by John Hennessey himself and the engine tech who builds your mill. All of this helps get your Hellcat to 60 miles per hour in 2.7 seconds, and it can do the quarter mile in 9.9 seconds at 142 mph. The Hellcat and it's 6.2-liter blown Hemi V8 are not for the faint of heart. Hennessey makes this Dodge downright demonic.

Dodge rolls out Shaker package for 2015 Challenger

Having an awesome Hemi engine under the hood can deliver impressive performance, but for those who lament not being able to see that big V8 engine doing its thing, hidden away under the hood, Dodge offers the Shaker hood on its Challenger muscle car.
