Perhaps its time for a new front cover. The best place for the water rad is
turning out to be on the spark plug side of the engine.  Unfortunately that
complicates the pluming somewhat because the water pump inlet and outlet are
on the other side of the engine.  Perhaps we should take a page out of the
RX8 design and make a new front cover incorporating the water pump housing
with the water coming out and going in on the other side of the engine.
Another problem is the pump should be mounted as low as possible so any drop
in water level will not cause the pump to cavitate.  We built some remote
pumps a few years ago that used the stock Mazda pump cartridge.  One other
point is the pump would be more eff.  if the water came stright into the
impeller.  Here are some shots of that remote pump.  I am looking for feed
back here.  Does anybody else have an ideas they would like to see
incorporated.

 If a new front cover is in the works, perhaps it would be a good time
 to incorporate the alternator system too, like the AeroVee.  It would
 help the up and coming one rotor crowd a lot, in terms of weight.

 That is not a bad idea but I think we need a lot more power than can be
 provided by a built in alternator. However perhaps a outboard motor type
CD
 ignition would not be too much trouble.

 Paul the alternator idea sounds good. There are diode and internal
regulator kits for the delco alternators used in the 1970's etc that output
120 amps. We would need a shaft extension on the e-shaft as there is no
unused space on it's length to accomodate the rotor of the alternator. The
stator should be easy to adapt. It would need to be on the outside of the
proposed housing away from hot oil and for cooling. The relocation of the
belt sheave can be coordinated with the water pump relocation since that is
about all it would be driving unless a dry sump is used. The alernator rotor
and a bearing behind the belt sheave would likely add 4" to engine length.
As an alternative location, the space between the dish shaped flex plate and
the rear iron might be used. Remember the model T ford generator was done
that way with permanent magnets on the flywheel.

Don't forget to add a an upper and lower accommodation for a rod end
vibration isolating turn buckle.

Yes that is a good idea. We could incorporate faculties for the rear motor mount.

I know somebody is going to say use the Lycoming type mount but unlike Mistral we are not changing the front end housings so I don't think half a dozen tiny six mm front cover bolts are up to the loads involved. Also all the 600 foot pounds of prop torque must travel all the way back through the engine to the  cantilevered Lycoming type motor mounts through those six mm bolts.
