Paul,  I admire  your work and design. However,  I think mine is a lot
easier to build. The intake will be finished in a week or so and will
include filtered ram air. In the photo  you are looking into the still
open end of the plenum. The plenum is just clamped together.  The four
injectors likewise are just stuck through the ports in the plenum at
this point but have an o ring which will seal when the fuel rail is
drawn tight.   It is going together nicely so far.   The runners, bell
mouths, and plenum will be a  one piece  welded assembly when finished
that is attached to the throttle bodies with hose and clamps.

Only two attached photos were readably. Did you intend to send 5 photos?

Looks a lot like one of my 3D's :)

I did not want to get that radical as this engine does not belong
to me so I took a more conservative approach  as to injector placement.
I have not built a plenum yet and won't. I don't need it for the
dyno runs. I will leave that up to the engine owner and builder as it will not affect the dyno HP reading and he will need to fit it in his cowl. This is mainly an exercise to see if we can equal the HP
per rotor and BSFC achieved in the Lemans engine.

I am glad that you are trying out the injector mounted outside
the trumpet opening. Widely used on race cars in the past but I still have a few questions about it in regard to aircraft use.  I am sure you will let us know how well it works. If you pay shipping I will
be happy to test your engine on the Mazdatrix dyno when it again
becomes available.
