I reversed it again to make the cylinders stationary and added four walls
of the plenum chamber and a throttle body for concept clarity. We don't need
much plenum room as our RPM range is much more narrow than that required
by a car. This 3D does not show the total room needed. Depends
somewhat on the max RPM of the engine used and the PSRU gear ratio.

Paul, Your layout looks great, I might be coming over to the individual hydraulic idea. I still
believe the step out on the runner is better though. Unless you knife edge the inner tube with a
LONG taper it causes a bunch O' turbulence. The plumbing is better this way though. The Lemans
runners are bell side in if you check. It does cause a vacuum drop but the loss is minimal. Bill

I would rather knife em as doing it the other way adds greatly to the bulk
of the whole mess. Well maybe not if the plenum had tunnels. Then you wind
up with a structural problem. This is a much cleaner way of doing it.
