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-12

Overview

The Nitrous Express Billet Supercharger Lid Water Methanol & Nitrous Kit is a precision-engineered upgrade designed specifically for Dodge Hellcat and Demon models equipped with the 6.2L HEMI engine from 2015 through 2023. This billet aluminum supercharger lid replaces the factory lid to provide enhanced airflow and integrates a spraybar-less nitrous and water methanol injection system. By injecting nitrous oxide and water methanol directly into the supercharger’s air discharge, this system cools the intake charge and increases oxygen density, resulting in significant horsepower and torque gains.

Ideal for performance enthusiasts seeking a clean, efficient, and reliable method to boost power, this kit offers a seamless installation with no need for spraybars or additional plumbing complexity. The design ensures even distribution of the nitrous and fuel mixture to each cylinder runner, maximizing combustion efficiency and power output.

Key Features

This billet supercharger lid kit incorporates advanced technology and thoughtful engineering to deliver superior performance enhancements:

• Direct replacement for factory supercharger lid for a quick, clean install
• Spraybar-less nitrous system with CNC-machined passages for precise fuel and nitrous delivery
• Improved airflow design to maximize air volume and velocity through the supercharger
• Water methanol injection integrated to super-cool the intake charge and reduce detonation risk
• Even distribution of nitrous and fuel mixture across all intake runners for balanced combustion
• Compatible with factory intercoolers, enhancing their cooling efficiency under boost
• Constructed from high-quality billet aluminum for durability and heat resistance
• Includes a 12lb carbon bottle for lightweight, efficient nitrous storage

Construction & Design

The billet supercharger lid is CNC-machined from premium billet aluminum, ensuring exceptional strength and precision fitment. The integrated nitrous and water methanol passages are engineered directly into the lid, eliminating the need for external spraybars and reducing potential leak points. This design not only improves reliability but also optimizes the spray pattern for consistent and effective distribution of the nitrous/fuel mixture.

The lightweight 12lb carbon bottle included in the kit offers a durable and corrosion-resistant solution for nitrous storage, contributing to overall system efficiency and ease of use. The entire assembly is designed to withstand the high temperatures and pressures associated with forced induction and nitrous oxide injection.

Performance & Sound

By injecting nitrous oxide and water methanol directly into the supercharger’s air discharge, this system significantly increases the density of the intake charge, resulting in notable horsepower and torque improvements. The water methanol injection also helps reduce intake air temperatures and suppress detonation, allowing for more aggressive tuning and safer operation under high boost conditions. While the primary focus is on power gains, users may also notice a subtle change in engine sound due to the enhanced combustion characteristics.

Installation & Fitment

The Nitrous Express Billet Supercharger Lid is designed as a direct bolt-on replacement for the factory supercharger lid on 2015–2023 Dodge Hellcat, Demon, Challenger, Charger, Durango SRT Hellcat, Trackhawk, and TRX models equipped with the 6.2L HEMI engine. Installation is straightforward and requires no permanent modifications to the supercharger or intake system. The integrated nitrous and water methanol passages simplify plumbing and reduce installation time compared to traditional spraybar systems.

Professional installation is recommended to ensure proper setup and tuning of the nitrous and water methanol injection system for optimal performance and reliability.
