Chrysler 300: Powered by the Spirit of a Demon?
Chrysler 300 is powered by a Redeye engine, not a Demon engine, but the result is still impressive.
It has become incredibly popular to swap the modern supercharged Hemi engines into all sorts of vehicles, with both Hellcat and Demon powerplants ending up in everything from classic muscle cars to Jeep Wranglers. In a recent video from the STREETMACHINETV YouTube channel, they traveled to Dontex Automotive Performance in Australia for a look at a Chrysler 300 with what the video claims is an engine from the Dodge Challenger SRT Demon.
It probably isn’t a Demon engine, as it is lacking some key features of the Demon-specific Hemi, but we suspect that it is a Redeye engine. In fact, Lee from Dontex Performance mentions that it is a 2019 Redeye engine early in the video, but in the end, the list of modifications allow it to make more than 960 horsepower at the rear wheels.
Chrysler with Demon-like Power
The video begins with the on-camera host introducing us to the 2016 Chrysler 300 SRT, which is powered by a “2019 Demon Redeye” engine. As you likely know, the Demon was only offered in 2018, and the Demon and Redeye are two different models.
The host talks about how much power the Demon had when running on 100-octane race gas, providing us with a close-up look at the supercharged Hemi. We can see that the IHI supercharger is wearing a bright red Demon badge and the host talks about it being a 2.7-liter unit, but this “Demon engine” is missing a key feature.
The 3,300 2018 Dodge Challenger SRT Demons sold in the United States and Canada had one key physical difference from the Redeye engine that was introduced a year later. The Demon has bright red valve covers while the Redeye has black valve covers.
It is possible that, for whatever reason, the shop decided to get rid of the bright red Demon valve covers in favor of the black Redeye covers, but that seems unlikely. If you are going to brag about having a Demon engine, would you remove a key physical feature like bright red valve covers? Probably not.
It should also be noted that at one point in the video, they show a Hellcat engine outside of the car with the distinct orange valve covers. There is also a shot of an engine without the supercharger with orange valve covers and engine block in the engine bay, so it looks as though at one point, this 300 had the standard Hellcat Hemi under the hood.
He goes on to say that it has the intercooler chiller system of the Redeye and Demon, so we wonder if this might be a Hellcat Hemi with a Redeye supercharger, valve covers and cooling system. Perhaps it had an original Hellcat Hemi and now has a Redeye engine. We aren’t sure about that, but we are pretty sure that this isn’t a 2018 Challenger Demon engine.
Built Hemi
While we don’t think that this Chrysler 300 is actually powered by a Demon engine, it is still packing a monster Hemi. The 2.7-liter supercharger has been ported for better flow and fitted with a 105-millimeter throttle body, while a 2.85-inch upper pulley and a 10% lower pulley lead to around 22 pounds of boost pressure. To work with all of that air, this Chrysler 300 also features a Fore Innovations fuel system and a custom tune for E85 ethanol blend.
At the end of the video, we get to watch as this Redeye-powered Chrysler 300 makes a pull on the hub dyno. It sounds amazing and when the numbers pop up on the screen, they are just as impressive as the sound. This supercharged sedan makes 960.6 at the rear wheels, which with an 18% drivetrain loss factor leads to around 1,170 horsepower at the crankshaft.
The video host claims that they expect for this Chrysler 300 to run in the high 8- or low 9-second range. With a curb weight of 4,000 pounds, this sedan is going to need more than 960 wheel horsepower to get anywhere near the 8s, but this car should be a solid 9-second car.
