They're cone-shaped impingement nozzles. That's not a garden hose, it's a pressure washer hose at 1000 PSI.
While its going you can wave your hand 4" from the nozzle and not feel the water impacting your skin, but your hand comes away soaked. I don't think the "atomization" is sub-par in the slightest, but maybe there's some other feature of nozzle design I'm not aware of. I wouldn't imagine that pattern alone is that big of a problem, especially not when nobody says that it's critical to align the fan nozzles perpendicular to air flow (or do they?).
My leading theories are... that injecting into a stock 1" square non-intercooled first gen intake horn causes water to pool all over and form droplets that take forever to disperse... that it's what you get when you inject water into a 400,000 mile engine... that there just aren't that many people running 1000 PSI over the course of minutes...
Maybe one day I'll use some of the off-the-shelf nozzles that everybody else uses, that'll eliminate my nozzles from suspicion or condemn them. I should have my truck up and running within a couple weeks, hopefully I'll have my new datalogger up within a couple month, I'll just keep rehashing my milkshake woes until I have some additional data.
At any rate, of course there's a point where too much nozzle will cause the water injection pumps to drop pressure and you'll get worse atomization. I believe they say that's around with two of their "625" nozzles? I'd hope somebody knows. Regardless, they seem to work beyond that.
I don't know, too many people using the kits as straight bolt-ons, not enough experimentation with them.
