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.

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