Flow rates for nozzles

[Roger Heflin]

Running out of water on a water injection system will cause the engine
to knock, so getting too much air  (and given the amount of air ithat
most engines use, I really cannot see a hose of the size you would be
using suppling enough  air to make any significant difference).
Running out of water when you are using it to allow more advanced
timing would be potentially fatal to your engine no matter how you do
it.   Probably it would be best not to run out of water with any
system, since the water pump will also probably pump air pretty good
too.  Also the nozzles may limit the air soo much that there is not
enough volume to worry about (of air).
