Paul,
This is great if we could find somebody on this side of the pond the whole
intake tract could be made out of this and a couple of pieces of straight Al
tube with some injector bungs welded in or bell mouths to work with your low
pressure injection system.

I had the water plumbing in mind :)
As long as the slide throttle is next to the engine
it would work as intake runners.

Paul,
I will be working on my trombone soon (slide section) on the inlet manifold.
I figure going from 14" to 24" , having a 6" slide section for the single
rotor. Considering I will be using an RX8 rotor and a smaller diameter inlet
tube, I consider it should be sufficient length to fins optimum length for
this configuration - do you agree?

Why go to all that trouble? If your using it as an aircraft
engine you will take off at max power around 7500 RPM and cruise
at 6000 RPM. An 18 to 19 inch long runner 2 inches in OD is
perfect for this speed range. Peak HP at 7500 RPM and peak BSFC
at 6000 RPM.

Trombones are good for racing cars.
