At my request, Bruce built the 20B for my
RV-8 using a manual trans 3rd gen rear side housing so it bolts up to the RD-1B
just like any 2nd gen 13B. This caused a few engine build issues (no time
to describe now). If using a stock 20B it should be easy to fabricate
a bracket to compensate for the missing bolt hole (Easy for me to say since I
didn't have to do it : ) Al Gietzen's integrated solution to this
problem and relocation of starter is elegant, light and as usual for him,
esthetically pleasing. But what is exactly right for his installation may
not be right for yours.
Look at the holes you have to work with (I'd
suggest looking at the starter mount holes in the 20B engine block first) and
envision the part that it would take to go between there and the engine adapter
plate. It really can't be too hard. I'll take a look at the
standard 20B down in the shop and post whatever comes to mind.

what is Tracy doing with his
installation? I look at his web site pics but can't distinguish the
model type he has. I'd ask him, but he's a bit busy right now. I,
too, bought the bed type engine mount.
I'd love to fly out
in oct and see all of this firsthand. maybe mike mcgee could join
me. I just need 2 vfr days.(best when back to back!)

Kevin;
That is the 20B
rear housing. Tracy’s adaptor plate
does not use the 12:00 hole Mark
mentioned as you can see on the first attached photo. The adaptor
plate bolt that has nowhere to go is the one I now use as the bottom bolt
for the starter mount. You may be able to see on the second photo, I
made a bracket from steel angle that bolts to the two starter mount holes;
and then drilled for the adaptor mounting bolt (nut required). It also
is one of three bolts for my engine mount plate.
BTW; for those
who may not have seen this before, it was my solution to the
6:00 starter position
that didn’t work for me.

I guess I
was confused by all the discussion on the ACRE list about bell housings and
figured I would need one. I have mostly completed an intake and
decided to let the turbo wait until phase 2, but still am building my belly
scoop and doing the easy to solve sheet metal stuff. I need to start
learning about the redrive. at one point someone was ready to try
flying the electric prop on his plane and then, nothing more was said about
it.
here's the photo again. I need to dig up the CD Bruce sent with the
engine and find out what I actually bought.

There is only
one bolt on Tracy’s adaptor plate that does not go on the 20 rear housing,
and that is at the starter position. No too tough to make a bracket the
accept that bolt.
BUT, I don’t
have that photo anymore; but I think Bruce put on a 13B rear housing – is
that right, Kevin?
