It seems we can’t go a day around here without showing you some sort of Hellcat content and there’s a reason for that. The engine is the most fearsome mass produced power plant to ever leave Detroit and having had first hand experience with it ourselves, we can tell you that you should believe the hype. In box-stock factory form the thing has hair on its teeth. We’re talking just flat nasty.
Now that you know that, understand that all over the country there are shops and engine builders working to wring even more power out of these supercharged bombs. Arrington Performance is one of the most respected names in Chrysler performance and they are the people who put this video online of a 6.2L Hellcat engine making a pull on their dyno. We’re not sure what they have done tuning wise, but the engine has tube headers on it and likely some work done to the calibration. Could there be a smaller diameter blower pulley present? Certainly a possibility but there’s no information given on the changes made.
What we do see is the engine get pulled on the pump. It seems that they are sticking with the factory-ish 6,300 RPM rev limiter because that is where the test stops. We’re literally taking a wild guess that this was done because the internals of the engine are stock and they didn’t want to overtask the factory pieces. All his being said the engine lays down some absolutely mind boggling numbers. From 4,500 to just about 5,500 rpm the engine torque is over 700 lb/ft. The horsepower hits 700 at 5200 RPM and peaks at 773.5 when the test ends at 6,307 RPM. All the while the engine barely sounds like it is breaking a sweat.
These numbers in ANY classic hunk of Mopar iron would result in a mind melting awesome combo. Us? We’d find the biggest early 1970s Plymouth wagon we cold and stuff that bad boy right in there.
