The supercharged Hemi V8s that power Dodge’s Hellcat models are the engines that just keep giving it. Giving horsepower, yes. The latest bumper crop of motorcycle ponies is thanks to kits that are part of the newly launched Mopar Direct Connection line of performance parts. These kits can add a little to a lot of extra fuss to a Dodge Challenger SRT Hellcat.
The tuning kits leading to our headliner issue are only available on Challenger Hellcat models, both regular Hellcat and Hellcat Redeye. They start with the Pre-Stage kit, which comes with a handheld flash tuner for both variants, plus a different air filter and low-temperature thermostat for the Redeye. Both kits add 5 horsepower to their respective models, and it’s required for the following Stage packages. The regular Hellcat Stage 1 package adds a smaller 3.17-inch supercharger pulley from the Hellephant crate engine and a code to unlock the engine sound for it. It brings power to 757 horsepower and 696 pound-feet of torque. The Redeye’s Stage 1 package is just a code for an engine tune, but in “high-octane mode” it lets the engine deliver 840 horsepower and 770 pound-feet of torque, the same specs as the Challenger Demon.
The Stage 2 kit is just for the Redeye and adds the Hellephant pulley and a different engine noise. It boosts power to those wild 885 horses, as well as torque to 787 pound-feet. It requires purchase of the Pre-Stage and Stage 1 kits. All of these upgrade kits are legal in all 50 states and do not void the manufacturer’s warranty when installed by a certified “Power Brokers” dealer.
The list of available parts goes well beyond these adjustment kits. There are a ton of other Challenger parts coming from the high-end Hellcat and Redeye models. They include cylinder heads, driveshafts, differentials, pistons, rods and torque converters from the Redeye. There are also Hellcat body parts and rear suspension knuckles to reduce camber and improve rear tire contact patch when launching at the drag strip.
For competition, you can basically order every single part of the Challenger Drag Pak car to build your own drag racer. And of course there are now the crate engines of each of the V8 Challengers for sale. The 1,000 hp Hellephant is also available. You can view the entire catalog via this link.
