Hellion Twin Turbo System For NON Hellcat Powered Challenger/Charger/300C Magnum 5.7L/6.1L/6.4L

Add serious boost potential to your HEMI platform with the Hellion Hidden Twin Turbo System. Engineered for both performance and fitment, this system delivers smooth, responsive power while maintaining a clean, factory-style appearance under the car. It’s designed for enthusiasts who want strong, consistent boost without sacrificing drivability or everyday function.

Key Features:

• Hidden design: The system mounts discreetly under the vehicle, keeping the engine bay uncluttered and maintaining a stock-like look.

• Twin turbochargers: Dual turbos provide fast spool and broad power delivery, offering excellent throttle response and strong mid- to top-end performance.

• Complete bolt-on system: Includes intercooler, piping, oil lines, clamps, and hardware — everything needed for a proper installation.

• High-quality construction: Stainless steel piping, TIG-welded connections, and precision-machined components ensure durability and consistent results.

Want it installed? Our technicians can install it at our shop in Marengo, IL, and we tune it on our in-house chassis dyno, by appointment. Street tuning dials in drivability.

Not local? Many Mopar and Ford combinations can be tuned remotely with HP Tuners.
