Stage 1+ NA: Single-stage flow based on the value from the Wide Open Throttle Switch.

Water/ Methanol Injection pump has no pressure cut-off switch for eliminating any oscillation/pulsation. Internally bypasses for a smooth constant even flow at the nozzle.  Our standard water-methanol pump is suitable for up to 1000hp. If you need more than 1260 ml/min or 20 GPH. Please choose the bigger pump and controller.

The new integrated solenoid valve and the nozzle assembly offers 100% safety for all injection systems utilizing a rear-mounted reservoir, injection points under vacuum, or installs where injection nozzle is lower than the water-methanol reservoir. The solenoid fits nozzle between the pump and injection point and locks fluid in place when not in use adding safety and peace of mind to any injection system. The solenoid mounted nozzle works as injector style. Because the reaction time is fast.

All metal equipment has the durability to corrosion of methyl alcohol and water, which constitute corrosion impact-resistant nickel-plated brass, brass, and EPDM grade plastic material.

All of our products are guaranteed for 2 years against the fabricated problems from the date of receipt by you.

Nozzles have a flow rating of your choice:
