Your injection rate appears to be pretty close to my 4 gallon/hr nozzle that I ended up down sizing to a 3 gph ( may go to a 2 gph in the future depending on temp readings when I get my intake air temp stuff in).

Your injection location is just about identical to mine. I am wondering if in both our cases part of the problem is water dropplets forming on the intake tract wall and then skinning down the surface of the intake tube ( like water dropplets run up a wind screen at speed ).

If that is the case -- aside from reducing the injection rate one possibility would be to put a small step in the intake tract just before it reaches the turbo. This would force the large surface dropplet to break off and re-suspend in the air stream.

I would love to do some experiments with a plexiglass tube to see if that is what is happening, and what step shape would pickup the dropplet and re-introduce it into the air stream.


Just a thought.
