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-05

Overview

The Nitrous Express Billet Supercharger Lid Water Methanol & Nitrous Kit is engineered specifically for Dodge 6.2L HEMI Hellcat engines from 2015 through 2023, including Demon, Challenger, Charger, Durango SRT Hellcat, Trackhawk, and TRX models. This advanced Stage 2.5 system utilizes a progressive VC-50 controller to deliver precise water methanol injection proportional to boost pressure, optimizing engine cooling and performance. By effectively increasing octane levels from 91 to the equivalent of 116 octane race fuel, this kit enables your Hellcat to maintain full power consistently while improving drivability and protecting against detonation.

Designed for enthusiasts seeking reliable and efficient power enhancement, this kit integrates seamlessly with your vehicle’s supercharger lid, providing a clean, OEM-quality installation that enhances both performance and engine longevity.

Key Features

The Nitrous Express Stage 2.5 Water Methanol & Nitrous Kit combines cutting-edge technology with durable components to deliver superior 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 points for injection engagement and delivery curve tailored to engine requirements
• Proportional water methanol injection based on boost pressure for accurate and efficient cooling and octane enhancement
• OEM-approved Extreme Environment 300 PSI UHO water methanol injection pump with proprietary heat flange, twin seals, and custom motor winding for cooler, longer operation
• 100% methanol-resistant components including stainless steel, nickel plating, EPDM seals, and hard anodized finishes for durability and corrosion resistance
• Sealed and potted pump internals with O-ring connections to prevent moisture intrusion and ensure reliability in harsh environments
• Controller color customization with up to two colors to match or complement OEM gauge clusters
• Designed specifically for Dodge Hellcat supercharger lids for a clean, integrated installation

Construction & Design

This kit is built with high-quality materials engineered to withstand the demanding conditions of water methanol injection systems. The billet supercharger lid is precision-machined for a perfect fit on Hellcat 6.2L HEMI engines, ensuring a secure and leak-free installation. The pump features a proprietary heat flange and twin seals to maintain optimal operating temperatures and prevent premature wear. Stainless steel and nickel-plated components resist corrosion from methanol exposure, while EPDM seals and hard anodizing extend the lifespan of all wetted parts. The sealed and potted pump design protects internal electronics from moisture and contaminants, making it ideal for extreme environments.

Performance & Sound

By injecting water methanol proportionally to boost pressure, this system cools the intake charge, increasing air density and effectively raising octane levels. This results in improved combustion efficiency, reduced detonation risk, and consistent power delivery under all driving conditions. The enhanced octane rating allows your Hellcat to safely run more aggressive timing and boost levels, unlocking the engine’s full potential without compromising reliability. The system operates quietly and seamlessly, maintaining the factory sound profile of your vehicle.

Installation & Fitment

The Nitrous Express Billet Supercharger Lid Water Methanol & Nitrous Kit is designed for direct fitment on 2015–2023 Dodge Hellcat 6.2L HEMI engines, including Demon, Challenger, Charger, Durango SRT Hellcat, Trackhawk, and TRX models. Installation involves replacing the factory supercharger lid with the billet lid equipped for water methanol injection. The kit includes all necessary components for integration with the vehicle’s boost system and electrical connections. Professional installation is recommended to ensure proper tuning and system calibration for optimal performance and safety.
