Paul and everybody,  please comment:      I am thinking of placing
the butterfly and the injector in the insert.  This one piece would
require all the machining and the rest of the system could be plain
tubing.  The disadvantage would be  having the injector on the hot
side.   Shielding the exhaust pipes would have to be very well
thought out.  The advantages are throttle response (not so important)
and, according to the Leman engine tech paper, increased fuel economy
(very important).

Sounds OK to me. If you are using two inch tube you
could use this casting and put the injector over on the
cold side. Also it has the required bell mouth
which is worth 5% in HP. Jim Mederer says you get better
fuel consumption with the injector near the bell mouth.
Since you will be selling these it might be a good idea
to use what you sell :-)
