Nitrous Express Billet Supercharger Lid Water Methanol & Nitrous Kit

2015–2023 Dodge Demon, Challenger, Charger, Durango SRT Hellcat, Trackhawk & TRX 6.2L HEMI

Part #: 20972BMF-10

Overview

The Nitrous Express Billet Supercharger Lid Water Methanol & Nitrous Kit is a precision-engineered solution designed to enhance the performance and reliability of Dodge Hellcat and related 6.2L HEMI engines from 2015 through 2023. This Stage 2.5 system integrates a progressive VC-50 controller that intelligently modulates water methanol injection based on boost pressure, delivering optimal cooling and octane enhancement exactly when your engine needs it most.

Ideal for enthusiasts seeking consistent power gains and improved drivability, this kit cools the induction charge to produce a denser air-fuel mixture, effectively raising 91 octane pump fuel to race-level 116 octane. The result is sustained full power output with reduced risk of detonation, making it perfect for street, strip, and track applications.

Key Features

This advanced water methanol injection kit combines innovative technology and durable components to maximize performance and reliability:

• Progressive VC-50 controller with a bright 7-color O-LED display showing boost, injection percentage, low fluid level, secondary stage activation, prime button, and fault codes
• Adjustable start and full injection points for precise tuning of engagement and delivery curve based on engine requirements
• Proportional injection tied directly to boost pressure for accurate and efficient water methanol delivery
• OEM-approved water methanol injection pump featuring proprietary heat flange, twin seals, and custom motor winding for cooler operation and extended life
• Extreme Environment 300 PSI UHO pump designed with sealed O-ring connections to prevent moisture ingress and ensure durability in harsh conditions
• 100% methanol-resistant components including stainless steel, nickel plating, EPDM seals, and hard anodized finishes for long-term corrosion resistance
• Boost gauge functionality integrated into the controller, eliminating the need for separate instrumentation
• Customizable controller colors to match OEM gauge clusters or personal preferences with up to two colors selectable

Construction & Design

The kit is built with high-quality materials engineered for longevity and performance in extreme environments. The billet supercharger lid is precision-machined to ensure a perfect fit and optimal flow characteristics. The water methanol injection pump is uniquely designed with proprietary heat dissipation features and sealed internals to withstand moisture and heat, providing reliable operation over extended periods.

All fluid-contact components are constructed from methanol-resistant materials such as stainless steel and nickel-plated parts, while seals and hoses utilize EPDM compounds to prevent degradation. The anodized finishes protect against corrosion and wear, ensuring the system maintains peak performance for years.

Installation & Fitment

This kit is specifically designed to fit Dodge 6.2L HEMI Hellcat engines installed in Demon, Challenger, Charger, Durango SRT Hellcat, Trackhawk, and TRX models from 2015 through 2023. Installation involves replacing the factory supercharger lid with the billet unit and integrating the water methanol injection system using supplied hardware and wiring.

The plug-and-play design minimizes modifications, and the included VC-50 controller simplifies tuning and monitoring. Professional installation is recommended to ensure proper calibration and system integration for maximum performance and reliability.
