Multi Port WI, Nozzle Placement
 

I working on a multi port WI system, to ensure even water distribution. The nozzles will be placed in the individual runners of the intake manifold and the engine uses a turbo.

I want to have minimal evaporation before entering the cylinder, but I also want to place the nozzles at the right angle. I can have them situated either around 6 inches before the intake valve but they will spray at the same angle as the flow of air ie horizontal, or I can place them just before the head and have the nozzles at between 45-90 degrees to the air flow. Any thoughts?

Thanks
Phil

i am planning the same type of setup w a rotary. i plan a staged (2 per) injection in each of the 4 induction runners in the lower intake manifold. since the runners have an i d of approx 1.75 inches and i will be running 17 psi boost i was also wondering as to optimal angle of injectors. i plan to run a 150 psi sureflow pump.
