Paul, I got a new e-mail address since my yahoo mail stopped recieving the
newsletter. This is my first attempt at using it so if I don't get it right
I will send the new address by yahoo.  The new address is

   I posted a note
concerning factory accurate dimensions for the core engine parts to the
newwsletter just before being disconnected and was wondering if there was a
responce. I have adopted your suggestion concerning use of the center
housing for water connections which works well for the four and six rotor
configurations. I have a shaft coupeling figureed out using dual ring
fetters with a solid piece of rod pressed into the e-shaft just inboard of
the front bolt. it extends to the thrust bearing with the injection pump
drive gear bored out to fit over the coupling,pressed up against a shoulder
to locate it fore and aft, and a snap ring behind. My serpentine drive belt
running off a toothed belt sheave also on the outside of the coupling leaves
me unhappy with reliability so now the connector housings have no openings.
looking at the rx8 rotor housings and the small round coolant passages in
the die castings, it seems like the largest water passage back to the front
housing that is unobstructed seems to run through the P-port area. I was
wondering if any of the round passages get drilled out larger for water
flow. This being the coldest part of the housing due to charge cooling I
don't think cooling could be a problem, however water flow total area seems
less?
    also, using the side exhaust ports for reduced noise and possible lower
fuel use I can take the investment cast stainless heat shields out of the
iron side housings (bunch of dremmel cut off wheels but doable) and use them
in the new housings. At this point what about using magnesium zr aluminum to
cut down some more weight. The working temp for 356-T6 sand cast and AJ62
magnesium of the z series as used by bmw are very close with the magnesium
being slightly stronger. Bolt retention in the magnesium required helicoils
but there are unfortunately the intake, exhaust and water manifolds held on
with bolt flanges.

You need to send us some pictures or dwgs.
