I think the smallest nozzle they offer if your not remapping for the WI, just using it for reducing temps won’t necessarily need huge amounts as most of the magic happens inside the compression and ignition part of the cycle. The water particles absorb the combustion taking heat “out” so to speak and then themselves turn into steam.
Pulling this info from a dark corner of my head so might not be entirely accurate.
Chucking too much water in there can make it hard too ignite to mixture, quenching the spark so to speak.
Think there’s a way to calculate how much water based on fuel flow but that’s beyond me
