[Diy_efi] water injection

[ian]

Hi guys.

Im considering adding water injection to my little 1.0 turbo diesel
charade.

has anyone done something similar and has advice?

Im intending to use a washer pump and agricultural (metal) spray nozzle,
with a PWM controller that increases the pump duty cycle based on boost
pressure in the plenum. I was intending to spray directly into the
plenum, so as not to have water interfering with the turbo.

thoughts ?
