Water-methanol injection has come on strong in recent years; its use as an octane booster has allowed nitrous-oxide users to stuff more nitrous in the cylinders to optimize performance. In addition, water-meth injection helps to increase reliability by slowing down and stabilizing the combustion process. These new direct-port water-methanol injection systems from Nitrous Express offer a number of sweet features designed to take your ride to the next level.

Official Release:

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, high pressure push lock hose, 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.
