I Have a single 400 ml/min @40 PSI nozzle that I am trying to find the best place for the nozzle on the intake tube. I mounted the nozzle right after the turbo outlet but the pipe has 2 tight bends before the throttle body. So bench testing with the pipe made all of the fog condense into large drops after it makes contact with the first bend. Also it sprays with the direction of air flow.

Should I move the placement if so where is the normal place?

 

Can you post a pic of the intake tube?

 

I placed mine right in front of the butterfly valve.

Put it 1-2ft from the TB. Under real conditions the pipe is really hot and the air is moving very fast. You aren't going to have a condensation problem them.

 

That air is hauling *** when at full throttle.
It will not ha e time to collect on a wall.
For maximum cooling benefit you want the nozzle as far away from the throttle body as possible. after the inter cooler if using one.
