Thanks for the suggestions
parmas
The layout of the ducting was dictated to a large extent by the lack of
space on the intake side of the engine, and by the fact that I did not want
to get involved with building a custom intake manifold at this stage. It was
suggested that I could eliminate all but one of the 90 deg bends on the
discharge side if I entered the GZE manifold from below. While that may
have been possible, I felt that it would starve cylinders 1 and 2.
So I went with a layout that is as close as I could get to the factory angle
of entry into the top of the manifold. I have faith that the Toyota factory
engineers did some testing on the non-symetrical runner layout to make sure
that it worked reasonably well. I have also increased the throttle size to
60 dia and all tubes to 2-1/2" to try and keep flow losses down. This is my
first venture into supercharging, so I am more interested in creating an
engine that makes driving a pleasure, rather than ultimate power.
Mounting the pre-charger nozzle in the bend seems reasonable. I think that
I would mount it square to the surface of the tube to try and project the
mist as far out into the airstream as possible (penetrate the fast moving
layer of air on the outside of the bend).
The post charger nozzle where you suggest, or perhaps in the straight
tube below the small angle bend to place it out of the way of mechanical
damge. Again installed square to the tube surface.
My interest in recessing the tip of the nozzle comes from reading this page..

Allowing the cone to develop before exposing it to the "shearing" effect of
the airstream seems logical to me. It will still get sheared, but the droplets
will be finer and should disperse more effectively. Sound reasonable ?
