Can anyone say for certain without special photography of the airstream/mist moving under realistic conditions?
My view is that the finer the mist, the easier it is for the water to follow the air during sharp turns.
In my car I'll soon have the WI nozzles facing straight at the compressor eyes. I don't think it gets better than that.
But even for post-intercooler injection I'd expect sharp 90 or 180 degree turns to be an invitation to de-atomisation.
Maybe not pooling - heck, at 1 bar boost the airflow will be quite violent- but certainly not uniform distribution among the cylinders.
Maybe a relevant analogy is the positioning of 'extra' fuel injectors in older turbo conversions of n/a engines. No matter how well the extra injector was positioned, some cylinders would consistently run richer than others. Can't be that different with water mist.
