Nitrous Express Dodge Hellcat Supercharger Lid Nitrous/Water Injection Kit (100-400HP) w/5lb Bottle

This Billet Hellcat Supercharger Lid replaces the upper supercharger lid on all Hellcat Superchargers for a quick and clean install. Nitrous and fuel are injected into each cylinder from inside of the supercharger lid, providing direct port style distribution. Systems come standard as a single stage with jetting for 100 to 300WHP. This lid is made from a solid piece of billet aluminum with 1/8NPT machined directly into the lid.

Product Overview

The Stage 2.5 uses the progressive VC-50 controller (52mm Gauge) that proportionally injects more or less water methanol according to boost pressure. Start and full points are adjustable for engagement and delivery curve to match what the engine requires. Proportionally injecting according to boost pressure gives an accurate delivery of water methanol and allows cooling and performance improvements over a wide range for improved drivability. The Stage 2.5 Boost Cooler will make the induction charge colder, denser, and increase 91 octane fuel to 116 octane race gas levels allowing full power all the time! The VC-50 controller offers the functionality of a boost gauge and water methanol controller all in one! Highlighting a bright 7 color (Blue, White, Red, Yellow, Orange, Purple, Green) O-LED screen displaying boost, percentage of injection, low level, secondary stage activation, prime button, and system fault codes directly on the screen. You can tailor the controller color to match your OEM gauges or mix and match up to two colors! This kit utilizes the only OEM approved water methanol injection pump on the market with proprietary heat flange, twin seals, and custom motor winding to run cooler and longer than the competition. The Extreme Environment 300 PSI UHO pump is designed to be in the elements with O-Ring connections that are then sealed and potted to ensure no moisture can enter the pump internals. The Stage 2.5 comes standard with 100% methanol resistant components using stainless steel, nickel plating, EPDM, and hard anodizing to ensure years of continued use.

Important Note Regarding Nitrous & Pressurised Systems

Orders containing nitrous systems or other pressurised canisters may require additional handling and inspection prior to dispatch.

Due to the nature of these products and applicable transport and state regulations, each system is individually inspected, released, and purged where required to ensure compliance with air and road freight standards. While most orders ship within our normal timeframes, this process may occasionally result in slightly longer dispatch times than those advertised.

We do everything we can to minimise delays, and the vast majority of shipments move through without issue. If you are working to a tight deadline or require urgent delivery, please contact us prior to placing your order so we can confirm the most suitable options.

We appreciate your understanding and patience - this process ensures safe, compliant transport and delivery of your order.

Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase.

Product Details

Reference Information

Nitrous Oxide Systems, Supercharger Lid System, Water/Methanol, 100-300 HP, Wiring, Hardware, 5 lb. Bottle, Dodge, Hellcat, Demon, Kit

Nitrous Express has the upgrade your Hellcat wants! Their Billet Supercharger Lid for Hellcat/Demon applications replaces the factory supercharger lid for a quick and clean install. The improved airflow design of this new lid ensures maximum flow—and the placement of nitrous and water/methanol passages provides huge increases in horsepower and torque.

The system does not have a spraybar, so nitrous and fuel are injected inline with the supercharger air discharge. This means the fuel/nitrous mixture is swept evenly to each runner. Nitrous/fuel passages are CNC-machined into the lid itself, so the spray pattern is in the perfect location every time. Injecting nitrous into this pre-intercooled hot air discharge super-cools the air charge, resulting in increased flow across the factory intercoolers for maximum power gains.
