Those are streams, not droplets. See the problem?

There are a number of options that cut surface tension - acetone or other diluents - but it's un-ideal.

damn that pic is worth a thousand words. way to save me from hydrolocking my engine, thanks

i think a hose and nozzle would be the way to go, like a devilsown kit

I think a different injector design, or the right surfactant, would do the trick.

Injectors are designed to atomize gasoline, not water. Thus, a different injector design. As for my vocabulary... I was raised in a trailerpark, what's your excuse?

Devilsown adds water according to manifold pressure, right? So what's the difference between 20lbs at 5k rpm and 20lbs at 7k rpm? I pretty sure there is a significant difference, but does the devil know this?

Correct. Injecting water with no regard for VE in a VE-based system, water to airmass ratios, etc.
