Chrysler almost smothered the Hellcat before it lived

Chrysler's 6.2-liter supercharged Hellcat V8 was an absolute sensation from the very moment it was announced, and honestly, how could it not have been? Packing 707 horsepower and 650 pound-feet of torque, its numbers immediately put every other production muscle car (and many supercars) to shame. Plus, we soon learned that would be wrapped in a package retailing for around $60,000 - a pittance compared to other vehicles offering similar grunt. However, the Hellcat almost never got the chance to rumble under the hood of the Challenger and Charger.
The Hellcat was initially proposed back in 2011, back when Fiat was deciding its future strategy for Chrysler Group, according to Automotive News. At the time, the company was just emerging from its bankruptcy doldrums, and an ultra-high-performance V8 wasn't exactly a must-have item. The program didn't move forward. However, SRT engineers kept fighting, according to AN, and four months later, they received the green light to pull the project off the shelf and continue developing the Hellcat. The muscle car world is certainly better for that decision.
The work of those engineers focused on taking Chrysler's standard 6.2-liter V8 and making it reliably handle all of the extra power from the supercharger. "It came down to micron levels of changes in the crank to be able to withstand the pressures of the engine," said Chris Cowland, director of advanced and SRT powertrain, to Automotive News. The changes amounted to switching out about 91 percent of the parts to make the Hellcat, including some quite minuscule alterations. For example, the washer holding the supercharger pulley is embedded with industrial diamonds to keep it from slipping.

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:

2020 Dodge Challenger Drag Pak comes solely with supercharged power

The Dodge Challenger Drag Pak has returned for 2020, five years after the last one arrived, and two years after it began development. And while in many ways it looks like past Drag Paks, there are a number of tweaks that should make this the fastest and most capable factory drag car yet from Mopar. Unlike the last model, only a supercharged 354-cubic-inch (5.8-liter for the imperically challenged) V8 is available. Mopar says it's more powerful than its predecessor, though exact horsepower wasn't given. It did confirm that the previous car was capable of a stunning 1,200 horsepower. The engine is coupled solely to a three-speed automatic transmission with a manual shifter. 2020 Dodge Challenger Drag Pak View 17 Photos Supporting the massive engine are many chassis, suspension and driveline enhancements. The independent rear suspension and axles are gone in favor of a solid axle from Strange and a four-link suspension. The front remains stock except for double-adjustable Bilstein shocks. The engine is mounted to a subframe member that's beneficial both to weight distribution and center of gravity. The car gets high-performance brakes and custom Weld Racing wheels with "DRAGPAK" engraved on them. The interior features a welded-in roll cage certified for quarter-mile times as quick as 7.5 seconds. Helping keep the car planted without increasing drag too much are front and rear spoilers from the road-going Challenger, a new addition compared with the previous car. Every Drag Pak car also comes standard with a wheelie bar and parachute. Dodge will only build 50 of these cars, and they'll only be offered as race cars that aren't legal for the street. The cars will be eligible for competing in sportsman classes in NHRA and NMCA drag racing series. Pricing and availability hasn't been set yet, but will be revealed sometime next year.
