Hi, fellow rotary enthusiasts....just a quick
update on the progress of my new intake system. I purchased the
Austrailian 90 degree intake manifold from Mazdatrix. I cut the top off,
and brought it to my machinist friend, who took a boring bar on a Bridgeport,
and plunge-cut two nice receptacles for my 90 degree aluminum bends. I
purchased two 4"x12" 90 degree bends from Burns stainless, as well as two 45
degree bends. I had them expand the end of the 4"x12" 90 degree tubing, so
that the 45 would slide right into it. It fit nicely. The machinist is now
making an aluminum mounting plate with two holes in it that the two 45 degree
tubes will slide into, and it will be welded on the outside. This mounting plate
has four 5/16-18 threaded studs screwed into it, to which my throttlebody will
mount. He put it on his computer, so he can duplicate this piece easily if
needed. It is a very simple system, with only one 90 degree bend to take the
tubes over the top of the engine, and then one 45 degree bend to position the
throttlebody on the cold side of the engine, similar to Paul Lamar's setup, with
the exception that the intake manifold goes from 4 into two right in the
casting, so only two intake runners are needed. Since the longer tube has
been expanded, I can slide the shorter 45 degree tubing in or out to fit just
where I need it, or for tuning the intake system. I should have everything back
from the machininst in a couple of days, at which point I will post some
pictures. I hope I described this sufficiently enough to confuse everyone. The
pictures will clarify everything much better than my description, I'm
sure.
Sure am sorry
I was unable to attend Shady Bend. Unfortunately, I had to work to pay for my
third manifold. Paul, the manifold collector,
