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.

Indications of 825 hp and emissions issues for Hellcat called 'speculation' by Chrysler

The 2015 Dodge Challenger SRT Hellcat is probably one of the hottest cars of the moment mostly because of its insane, 707-horsepower supercharged V8. However, there are conflicting reports coming out that the powerplant might be having problems with its emissions compliance and may be capable of even more power.
Jalopnik says that an unnamed source within Fiat Chrysler Automobiles told it that the Hellcat was having problems meeting emissions standards at its 707-horsepower tune. The person claimed that the automaker has been testing the V8 with different types of sensors, possibly to make it a bit cleaner in the future. Autoblog spoke to SRT spokesperson Dan Reid, and he said about the claimed poor emissions, "It's totally speculation."
The source also claimed that the Hellcat had been dynoed at a monumental 825 horsepower, internally. Based on the other rumor, though, it's hard to imagine the engine being emissions compliant like that. Autoblog also asked Reid about this speculation about more power and was told, "They are totally speculating about that."
