The engine bay of the 2021 Dodge Challenger Hellcat Redeye is one of the cleanest laid out and organized you will find in today’s landscape. It’s ready made for a car show, designed to look good with the 6.2-liter supercharged Hellcat engine its crown jewel.

In the Challenger Redeye and Challenger Super Stock similar, the high output version of the Hellcat engine puts out 797 horsepower and 707 pound-feet of torque and is mated to an 8-speed “Torqueflite” automatic transmission.

With the slick looking valve-cover shields off, it isn’t as pretty but you can see more of its components like the fuel rails for its injectors and the coil-packs for its spark plugs down on the sides. Down in front you can see that two drive belts are utilized, one for its supercharger and a second for all of the major engine accessories.

Following the airflow, the intake charge starts with a large open-element air filter which features a sealed box that draws air in both from a built in channel from the functional hood scoop and an also opening behind the fender. From there it goes through a huge throttle body and into the supercharger assembly.

There the air is cooled with an air-to-water inter-cooler system which here features an additional cooling tool called SRT Power Chiller. Here, the secondary coolant circuit can be further cooled by using the AC refrigerant when the system allows. The inter-cooler radiators are located down in-front behind the grille.

The supercharger itself blows up to 14.5 psi boost into the 6.2-liter iron-block engine which breathes through aluminum 2-valve heads operated via a single cam and pushrods. It’s 100-year old technology but it works.

Maintenance and service is made easy in-spite of the massive engine’s packaging. Checking the oil is done at the front passenger side of the engine. The oil filler cap itself is located at the driver side rear of the engine.

Windshield washer fluid is located at the passenger side front of the engine bay, the main fuse box just behind it. Further back you will find the coolant reservoir for the supercharger intercooler system secondary cooling circuit.

The main coolant reservoir for the engine is actually located at the driver side of the engine bay just behind the air filter box. Accessing the brake fluid reservoir requires removing a small black plastic access cover just ahead of the windshield.

Changing the air filter is likely the easiest task as accessing it is easy due to the open-element design of its air-box.

If you’re looking for the 12-volt battery, instead of under the hood it is located in the trunk area just below the floor. You also find there an emergency tire inflator kit as our Charger Hellcat Redeye does not have a spare tire.
