- Billet aluminum mounting plate with extended serpentine drive and secondary cog drive for durability
- Complete pulley system including 3.60" serpentine pulley, 32-tooth secondary drive pulley, and 30-tooth supercharger pulley
- OE Hellcat water reservoir tank with all necessary hoses, clamps, and plumbing for closed-loop cooling
- Compact water circulation pump and aluminum heat exchanger (22.6" x 9.5" x 2.5") for efficient thermal management
- Maxflow Race blow-off valve and reusable high-flow air cleaner for optimal airflow and boost control
- Recommended spark plug gap reduction to .032” for enhanced ignition performance under boost
Construction & Design:
The Vortech Supercharger Kit is engineered with precision and durability in mind. The supercharger housing and mounting components are crafted from billet aluminum to ensure strength while minimizing weight. The advanced centrifugal compressor stage is designed to deliver high boost pressure with minimal heat generation, improving both power output and component longevity.
The air-to-water charge cooler system features a welded aluminum core and lightweight ducting to maximize cooling efficiency and reduce intake air temperatures. This closed-loop cooling setup uses OE Hellcat reservoir components and a compact pump to maintain consistent thermal management, even under demanding conditions.
Performance & Sound
Utilizing Vortech’s V-3 Si-Trim supercharger, this kit can support up to 775 horsepower on stock engines and beyond 1,000 horsepower with upgraded fuel systems and tuning. The centrifugal design produces a smooth, high-pitched whine characteristic of Vortech superchargers, delivering an aggressive yet refined auditory experience that complements the Challenger’s muscular exhaust note.
Thanks to its high adiabatic efficiency, the system generates less heat and requires less engine power to drive, resulting in improved throttle response and overall performance gains without sacrificing fuel economy under normal driving conditions.
Installation & Fitment:
This tuner kit is designed for 2015 through 2023 Dodge Challenger models equipped with the 5.7L HEMI engine, compatible with both manual and automatic transmissions. Installation requires professional expertise to provide custom ECU calibration and the necessary fuel system upgrades, as fuel injectors, fuel pump voltage booster, MAP sensor, and ECU programmer are not included.
All mounting hardware, pulleys, belts, and cooling system components are supplied to facilitate a complete installation. Due to the custom tuning requirement, this kit is best suited for experienced installers or performance shops familiar with forced induction systems.
