Additional information

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

The 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. Suppose 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 offer 100% safety for all injection systems utilizing a rear-mounted reservoir, injection points under vacuum, or installs where the injection nozzle is lower than the water-methanol reservoir. The solenoid fits the 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 in 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 fabricated problems from the date of receipt by you.

Nozzles have a flow rating of your choice:

95cc / 125cc / 157cc / 189cc /  220cc / 252cc / 283cc / 315cc / 378cc / 378cc / 440cc / 504cc / 567cc / 630cc / 755cc / 880cc / 1000cc / 1130cc / 1260cc / 1575cc / 1890cc / 2200cc

1.5 GPH | 2 GPH | 2.5 GPH | 3 GPH | 3.5 GPH | 4 GPH | 4.5 GPH | 5 GPH | 6 GPH | 7 GPH | 8 GPH | 9 GPH | 10 GPH | 12 GPH | 14 GPH | 16 GPH | 18 GPH | 20 GPH | 25 GPH | 30 GPH | 35 GPH

100% Water:  10-15% Water/ Fuel ratio or 0.5-1cc per HP

%50-50 Water-Methanol: 15-20% W-M/ Fuel ratio or  1-1.5cc per HP

100% Methanol: 20-25% Methanol/ Fuel ratio or 1.5-2cc per HP

Please indicate which nozzle size and hose color you prefer before the ordered item. If you don’t specify the size, we will send you a 252 ml/min (4 GPH) nozzle and Red Hose.
