Description

Unleash Serious Power with the Gen 6 Whipple Supercharger System

Since 1987, Whipple Superchargers has led the way in twin-screw supercharging technology.

As pioneers of positive-displacement systems for fuel-injected, emissions-legal engines, they’ve built over 30 years of experience in supercharging excellence.

This is the most powerful supercharger system currently available for the Hemi 6.4L engine — the all-new Gen 6 Whipple Supercharger System.

Industry-Leading Cooling & Airflow

The Gen 6 system features a patented dual-core, dual-pass intercooler for unrivalled cooling capacity.

A massive 112mm inlet, Gen 6 3/4 rotors, and an upgraded belt system combine to deliver serious gains in power and torque with every pound of boost.

Race-Proven Performance

Trusted by Dodge’s factory-built Drag Pak programme, the Whipple Gen 6 supercharger system helps race teams set new records almost every weekend.

Engineered for industry-leading efficiency from idle to redline, it delivers strong, consistent performance whether you’re on the road or the track.

Advanced Engineering

The Gen 6 supercharger features all-new bearings, gears, rotors, and housing for improved durability and performance.

A 3/4 rotor combination, 285-degree helix, and optimised inlet and discharge ports increase efficiency across the board.

What’s Included

The kit includes high-flow fuel injectors, billet fuel rails, an oversized heat exchanger, a high-flow intercooler pump, pre-formed and fitted hoses, and all necessary wiring connectors for straightforward installation.

ECU & Compatibility Notes

  • Model years 2015–2023 and up require an unlocked PCM. Whipple includes an HP Tuners unlock code with every supercharger system purchase — the PCM must be shipped to HP Tuners for the unlock service.
  • 2018–2023 kits include a security gateway module to allow PCM reading/writing.
  • 50-State Legal: D-231-103 (MY18–MY23).
