Helps prevent/reduce drizzling volume.

Would the nozzle holders with the built in check valves serve the same purpose?

Depends on what style pump your planning to run.. Gear driven, electric? Electric motor driven you could get away without a valve inline and just use a hobbs switch but you will have a delay from time your hobbs sends signal to the time the pump actually gets pressure up to the nozzles.. Whereas if you run the simpson valve or similar mounted closer to then nozzles you have constant water flow recirculating until desired pressure closes the diaphram and water goes to the nozzles.

A 12v dc can go from 0 pressure to max system pressure very quickly. Also can be setup progressively with laptop based tuning to come on with boost, temp, time, etc. Set all the ramp rates to run a bigger nozzle overall without flooding the engine down low. And double the pressure as conventional pro systems.

Will be electric pump, being a puller I have a little more time to spare for it to come in.

Thank you for your help.

Its the same exact pump turning relatively the same rpm. Just using different sources to drive it.

Is it best to but the nozzle facing towards the air flow or away from?

There is less pooling when the nozzle is going with airflow. If your placement is perpendicular a wide spray pattern is helpful.

I will have to do some looking, they will be placed after the aftercooler but I cant recall how much room I have before the entry into the head.

If done properly it should add power. Or you would think it should add power

I'm looking at it for temperature control, getting exhaust temps to a safe range to sustain a long pull will be the best scenario for me.

In gasoline engines it makes it possible to use higher boost and timing. In diesels it makes it possible to add more fuel without melting so yes it kind of adds power but it is not from the water itself. If there is not a problem with temperatures then it only robs power.

How did you figure the flow rates, my system will only be three nozzles on a 855CID engine, I'm gonna guess I need to start fairly high, obviously fueling will make a difference but trying to get a place to start as engine isn't finished yet.
