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-00

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 integrates a progressive VC-50 controller that dynamically adjusts water methanol injection based on boost pressure, optimizing engine cooling and performance. By delivering a precise mixture proportional to boost, it enhances drivability while increasing effective octane from 91 to 116, allowing your engine to safely produce full power under all conditions.

Designed for enthusiasts seeking reliable, high-performance cooling and octane enhancement, this kit combines innovative technology with durable components to ensure consistent results on the street or track.

Key Features

The Nitrous Express Stage 2.5 kit offers a comprehensive solution for water methanol injection with integrated nitrous control, featuring:

• Progressive VC-50 controller with a 52mm gauge that proportionally injects water methanol based on boost pressure
• Adjustable start and full injection points for precise tuning of engagement and delivery curves
• Bright 7-color OLED display (Blue, White, Red, Yellow, Orange, Purple, Green) customizable to match OEM gauges or personal preference
• Integrated boost gauge and water methanol controller with real-time display of boost, injection percentage, low fluid level, secondary stage activation, prime button, and system fault codes
• OEM-approved Extreme Environment 300 PSI UHO water methanol injection pump featuring proprietary heat flange, twin seals, and custom motor winding for cooler, longer operation
• Sealed and potted pump design with O-ring connections to prevent moisture intrusion and ensure durability in harsh environments
• 100% methanol-resistant components including stainless steel, nickel plating, EPDM seals, and hard anodized finishes for extended service life
• Designed to cool and densify the induction charge, effectively raising octane and reducing detonation risk

Construction & Design

The kit is built with premium materials engineered to withstand the demanding conditions of water methanol injection systems. Stainless steel and nickel-plated components resist corrosion and methanol degradation, while EPDM seals and hard anodized surfaces provide robust protection against wear and chemical exposure. The billet supercharger lid is precision-machined for a perfect fit and optimal flow characteristics. The injection pump’s proprietary heat flange and twin seal design ensure reliable operation and longevity, even under extreme temperatures and environmental exposure.

Installation & Fitment

This kit is designed for direct fitment on Dodge 6.2L HEMI Hellcat engines from 2015 to 2023, including Demon, Challenger, Charger, Durango SRT Hellcat, Trackhawk, and TRX models. Installation is straightforward for experienced enthusiasts or professional installers, requiring no major modifications to the supercharger lid or intake system. The integrated controller and pump mount cleanly within the engine bay, and the system’s adjustable parameters allow fine-tuning to match specific boost levels and engine requirements.

What's Included

• Billet supercharger lid with integrated water methanol injection ports
• Stage 2.5 progressive VC-50 controller with customizable 7-color OLED display
• OEM-approved Extreme Environment 300 PSI UHO water methanol injection pump
• Complete wiring harness and connectors
