Looking to make a water inj kit on the cheap as a trial type thing.
Can get water injectors no prob, ERL ones.
Was thinking to use a fuel inj pump to power it but gotta coupla q's i was hoping i could get cleared up.
FYI am prolly gonna go with a .4mm jet activated by boost setting of approx 16psi. Gonna go for pump of about 7bar pressure, demon tweeks prolly.
1 - Will the pump be happy to maintain the full 7bar for however long its running? Might be a max of 30secs for the time it spends on that sorta boost throught the gears i spose when its gettin a good hiding.
2 - If you were to just connect the tank to the pump and then the pump to the injector then when its used it will pretty much hit the 7bar straightaway yes? But what happens when it stops pumping, will the line pressure between the pump and the jet just force out the remaining water until the pressure diminishes?
