Paul, Have attached various photos of throttle body and runners.
 Measurements are, butterfly to housing wall 5 inches, butterfly to
 plenum approx. 15 inches. The ruler shows where I can shorten the
 runners to if necessary, which can be as short as 14 inches total.
 regardless will run the motor as is to see what will happen, as the
 work is already done and I am keen to just get flying and worry about
 further mods after that. What do you think re runner length? With
 all the bits cut off the slide throttle, it is now a proposition to
 send it back to you for investigation which I will do when I get the
 time.

 Wow! impressive. Is that a custom throttle body?

 Since the throttle plates are close to the p-ports it should idle
 pretty good.

 Hard to say where the torque peak is. Has anybody in Oz dynoed that
 TB?

 You will have plenty of power no matter what. I would not bother to
 shorten the runners.

 You are going to be very impressed with the take off performance.

 Are you using Tracy's computer. You may have to retune to match the
 new manifold and TB.

 If you don;t mind send me the slide throttle by boat. No rush.

    Hi Paul,
            You may want to see this 6 rotor engine fitted to a car also
 billet throttle bodys.

 might be OK for a car but the e-shaft is a bit wimpy for a  heavy duty
 engine
 like an aircraft engine.

   Hi  Paul,
                  On the subject of "E" shafts how do they join the
shaft or is it just assembled from one end, I have never assembled a
rotary engine.

The 2 rotor is one piece. The 3 and 4 rotor are several pieces that are tapered and held together with a long bolt.
