Paul,

  Not entirely clear what your proposing to do with this "kit". Are you
talking about providing a ready to weld intake with flange, mandrel bent
tubes, plenum, etc..? Are you talking a plenum or dynamic chamber per
Tracy's description? Will the tube ends at the engine end be appropriately
reshaped to match the port shape? Will you pull the tubes in as close to
the engine as possible? Note that I do require the forward tubes be pulled
in tight to clear the cheekless cowl my RV -4 will get. The stock 88
manifold that I have and the builder fabbed manifolds that Ive seen
pictured here in the past with large radius sweeping mandrel bends wont
work  If so count me in for a 6 port version. Im attaching a picture of the
RB aircraft 13B as an example of something that will work for me.

  As for the port layout, if you like I can take some dimensions off of my
88 6 port tonite and draw it up in ACAD R14 and email to you as an
attachment. It will take me a couple of days to get that done. What kind of
a time scale are you talking about for this project? I'm ready to start on
an intake NOW.

As soon as I get some manifolds that are on the way. I have located
a guy to do the hydrocutting. The drawing might save me some time.
Thanks for the offer.

Just the tubes and the flanges as I see no economy of scale for
the rest of it. People will want to customize those other parts anyway
to fit their airplane. You could also experiment with tuning.

We might be able to organize a group buy on throttle bodies
and bell mouths.

BTW the ID of the Kinsler throttle body shown below is 
2.9 inches and that is about what you need. I forgot to mention
that when I uploaded the picture before. Can anybody tell me 
the areas or just the dia. of the stock Mazda turbo throttle bodies?
