OR, you can lower the voltage to the pump

 

if i lower the voltage to the pump there is a longer pause between the pulses. so much of a pause might cause issues with tuning and pre det. id rather get smaller nozzles. ill see how the 100ml/min work right now and then i can go down as far as 60ml/min for each port!

 

You could put an adjustable pressure regulator, or an FMU (which might work better: more water for more boost) inline from the pump to the nozzles. Not sure if it would rust or not
That way you could let the pump run where it was designed to run.

 

That is amazing!! Nice work!! You run it off a Hobb switch or something similar?

 

the pump came with a controller that senses boost and vacuum. its pretty simple once its laid all out
