Direct port injection

[chevyeater]

I'm checking into water injection for a project car and I'm wondering why I can't find a multi-port WI system. Everything seems to be single nozzle. This relies on the intake manifold to distribute water to the cylinders evenly. It does not seem like a good idea to me to rely on a dry flow manifold to flow water properly.

Is there something I'm missing?

TIA,
Brian
