Description

Wtr/MethInjSystm

NX direct port water methanol systems inject the water methanol mixture directly into each intake runner providing excellent distribution to each cylinder. These systems include a high pressure electric pump, stainless steel hardlines, filtered nozzles, nickel plated fittings and a composite reservoir. Stage one systems include a wide open throttle activation switch while stage 2 and stage 3 systems include digital progressive controllers that control water methanol output. Stage 2 controllers are adjusted by setting rotary dials on the progressive box. Stage 3 controllers include a LCD display and can be finely adjusted for low, mid and high airflow levels. The LCD Screen displays boost pressure, fuel injector duty cycle, as well as water-methanol injection percent.

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.

Water/Methanol Injection System, Gas, Stage 2, Direct Port, 8-Cylinder, Hard Lines, Kit

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!
