I'm currently experimenting with smaller nozzles, 0.4mm both before and after the compressor. Maybe the surge issue will be fixed now, we'll see.

My gut feeling at the moment is that Richard's recommendations on water volumes and activation pressures are a bit on the high side.
At least for well-intercooled engines! :wink:

I'd say someone should start with a 0.4mm nozzle at 1 bar, and take it from there.
Stock systems come with 0.5mm minimum and switch preset at 10psi. Too much water for a well intercooled 2 litre engine! Especially in the winter.
