Hellion Compound Boost Twin Turbo System (HT-15HLCT-TT) - 2015+ Hellcat / Demon / Redeye
The Hellion Compound Boost Twin Turbo System for Hellcat-powered Dodge vehicles represents the absolute cutting edge of forced induction technology. Designed specifically for factory-supercharged 6.2L platforms, this system combines the instant response of a supercharger with the massive airflow and adjustability of twin turbochargers—delivering performance levels that redefine what’s possible.
Hellion pioneered turbo systems for modern Mopar platforms and now raises the bar again with a true compound-boost solution. This system retains the factory supercharger and adds twin turbochargers to the inlet side of the blower, creating two stages of boost. The turbos supply the first stage of pressure, while the supercharger compounds it into devastating total boost at the engine. The result is monstrous torque, unmatched efficiency, and extreme horsepower potential with incredible control.
With proper supporting modifications, this system can be configured anywhere from slightly above stock output to over 1,600 rear-wheel horsepower. A supplied Turbosmart e-Boost2 controller with RPM-based control allows boost to be adjusted instantly from inside the vehicle. Want mild street power? Select a low boost setting. Heading to the track? Turn it up with the push of a button—no pulley swaps, no belt changes, no compromises.
The system installs without cutting or modifying the vehicle’s body and includes high-flow headers, massive turbo options, and factory-style intake routing that can be configured as a hidden sleeper setup or displayed proudly under the hood. For builders who prefer a twin-turbo-only configuration, the system can be plumbed accordingly using an aftermarket intake—flexibility is built in from the start.
This is the ultimate power solution for Hellcat, Demon, and Redeye owners who want the best of both worlds: the feel of a supercharged monster with the limitless scalability of a true twin turbo system.
