Hello Paul,
Thanks again for all of this info. Stuff is priceless. I contacted a
local rotary head and he is going to let me take one apart with him
to
see all of the little passages and such I cant make out from the
diagrams. This is getting fun.
My idea is to mate two separate stock rx-8 shafts by sliding each
end
into a coupler that is also the gear that connects to the
transmission.
I havent decided on the method of
attachment(splines,keyed,polygon,hirth) yet because I am looking at
which end to do it on. I am curious if the e shaft can be flipped
180
and still work correctly in the region between the two lobes. It
looks
to be symmetric in that region. Once I have the two keyed sides or
the
two tapered sides facing each other I will figure out exactly what
to
do. I am leaning toward the straight key side right now because it
has
more options to be machined and I would be able to use modified
balance
weights.
My second question is on the four rotor engine they commonly talk
about
a centralized cooling and oiling system. It is my understanding that
they treat the engine as two separate "convective" loops to control
the
temp gradiant across the engine. Is this assumption correct or is
that
just BS and they flow coolant and oil from one end all the way to the
other.

Yes that is true. A step towards real parallel cooling.

Paul,
What is the reason for the oil groove in the tapered side of the shaft?
It looks like the bearings are the same design in both of the stationary
gear.
By joining the two shafts together on the straight side would most
likely eliminate the oil bleed off valve that is normally there. Do you
think it would be possible/advisable to mount this to the tapered side?
Just one side or both?
Rob Woods
I am not following you here.
Load this jpg into MS Paint and mark it up and send it back. The groove
in the main bearing on the straight end (right side in this picture)
is how the oil gets to the E-shaft from the oil mains gallery located
on the top of the engine.
