Thanks for the input

If the water is more effective in the cylinders as droplets rather than
vapour, then it makes sense to move the post-charger nozzle closer to
the inlet manifold. I'm not sure which position you are recommending, so
I have marked them here...
On top of the last bend would give a straight shot into the manifold, and
probably separate a fair amount of water out on the manifold floor. However
this will find its way into the cylinders no problem as the engine is installed
with a slight slope.
Will it make any significant difference if the nozzle is mounted radially to
the bend, or axially to the following tube ? Same situation applies to the
pre-charger nozzle.
