Nitrous Express LT4 Supercharger lid nitrous systems replace your factory supercharger lid on GM LT4 Superchargers for a quick and clean install. The lids feature an improved airflow design that can increase up to 25 hp by itself, and increase power even more when your system is activated. Nitrous Express LT4 Supercharger lid systems are available as nitrous and nitrous/water methanol systems, with or without bottles. The nitrous spray bar system injects nitrous and fuel above each intake port, providing direct port-like distribution and ensuring maximum performance. Nitrous systems include: * Billet aluminum and carbon fiber lightning solenoids * Industry exclusive billet aluminum Lightning 500 bottle valve * Stainless steel braided lines * Stainless steel bottle brackets * Wiring, switches, and jetting for 100 to 300 wph Nitrous and water/methanol systems will also include: * Billet aluminum and carbon fiber lightning water/methanol solenoids * High-pressure electric pump * Stainless braided soft lines * Pre-bent stainless steel hard lines * Filtered nozzles * Plated fittings * Composite reservoir * Switches * NX Stage 2 digital progressive methanol controller

You'd be crazy to throw water into a gas tank and expect to get anywhere—but power and torque can be increased if you inject it into the incoming air charge with Nitrous Express water/methanol injection systems. Cooling the air charge allows for increased timing and the resulting performance benefits. These versatile units have a wide-open throttle switch for naturally aspirated vehicles and an adjustable boost-activated switch for forced induction models. Nitrous Express systems inject a fixed amount of fluid when the WOT switch or boost is activated—and continues until the switch opens again. They reduce intake temperatures and the need for timing retard when used with nitrous. Stage II kits come complete with a high-output pump, 3 qt. reservoir, nozzle, boost activated progressive controller, switch, hardware, and detailed instructions. Water has always been used to cool down motors, but with Nitrous Express water/methanol injection systems … it'll be heating things up!

Nitrous Express has the upgrade your Hellcat wants. Their Billet Supercharger Lid for Hellcat and Demon applications replaces the factory supercharger lid for a quick and clean install. The improved airflow design of this lid ensures maximum flow—and the placement of nitrous passages provides huge increases in horsepower and torque. This system does not use a spray bar, so it injects nitrous and fuel inline with the supercharger air discharge. The fuel/nitrous mixture is swept evenly to each runner. 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. As mentioned, this system does not utilize a spray bar, which means that the nitrous/fuel passages are CNC-machined into the lid itself; the spray pattern is in the perfect location every time. The system includes: * Ready to bolt-on billet supercharger lid * Billet fuel line adapter * Lightning Series billet aluminum and carbon fiber nitrous and fuel solenoids * Stainless steel braided lines * All wiring, switches, and mounting hardware * Jetting for 100, 150, 200, 250, and 300 hp * Systems with a bottle include stainless steel bottle brackets and industry exclusive Lightning 500 bottle valve
