How do you get the fuel in, or is this for the Rand Cam sportplane that
doesn't use fuel ? :)

John

I thought you would never ask :) The easiest way is to make the shoe
box big enough to contain the injectors and the fuel rail.
These are the old type large diameter injectors. The new slim
RX8 type are easier to fit side by side in a two inch tube.

-----------------------------------

In case you were wondering wheather this would fit under the cowl
here is another 3D. The great thing about the Schertz beam is there
is plenty of room down alongside the engine for a muffler
or an exhaust system or a large TO4 turbo if you wish.

Paul,
Is the purpose of the adjustable intake length so we can fine tune for
prop/performance? To find that sweet spot rpm?

In theory you get a lower fuel burn if the intake length is tuned
to cruise RPM. You get more power if it is tuned to max RPM.
