Paul,
   We have a plan to install an ignition/alternator stator under a thin
   flywheel prior to a standard flywheel as illustrated here. The one shown
  is
   just for illustration and is not large enough in diameter. We need a
  stator
   @ 7 inches in outside diameter with the the appropriate flywheel.
   We have talked to a stator manufacturer who will build us one like we
  need
   but he wants a bag full of gold.
   Dimensionally it will fit and function as required.

   What we ask is if anyone knows of a thin(@ 1 inch thick) stator @ 7
  inches
   in diameter with @ 5 inch ID already in existence so that we do not have
  to
   cough up that bag of gold. The manufacturer says his design will fit in
  the
   cavity and not disturb the remaining stackup of the drive.
   The ID of the stator shown is @ 4.5 inches.

   If we can approximate the dimensions required of the stator, I am told
  the
   any stator can be rewound to accommodate both ignition and 10 amp
   alternator. I must confess I am not sure about the electrical aspects,
  but
   am fairly certain we can mechanically accomplish the installation. Right
  now
   our mission is to show mechanical fit.

   That looks cool Milo.  There are dozens of stator designs for out board
   motors and some motorcycles. Check out the one for Harley's. Pictures
   attached here.

   It looks about the right diameter. It lacks high voltage coils for CD
   ignition
   but it should put out enough current for stock RX8 coils. All you would
  need
   is a small sealed lead acid battery.

   BTW I need the room in my hangar for the RV4. When do you plan to
  retrieve
   your
   RX8 motor test stand/trailer. I'll throw in the RX8 heat sink mount and
   wiring for
   free. The wiring is not quite done but close.

Matt,
Thanks for the read, very interesting.
Our goal is slightly different! With @ 7 inch OD stator with @ 5 inch ID
will permit us to mount the stator solidly to the engine block reducing
vibratory forces imposed by Tracies plate, and the magnet flywheel mounts
directly to the engine driveshaft with minimum interceding elements.
However this may not come to pass unless we can come up with a suitable
stator and flywheel. We looked at the Harley setup, but the
diameter of the system was too small. Additionally it is very heavy and we
wish to accomplish ignition as well as alternation, and timing all in the
same package much like small motorcycle setups.
We are told by a manufacturer that the space available underneath the engine
flywheel can do the job if we use a current thin technology stator &
flywheel. We have determined that it is essential that the magnet flywheel
be precisely balanced whichever system one decides to use.
The search is on for an appropriate stator/flywheel setup to match our
needs. Thanks for the info.

    Hi MiloThe Evenrude magnet wheel is already wrap with carbon fiber a while
ago and i was waiting you did your moving to Texas before to send it to you
for machining.This wheel will need to be balanced and it will required more
fiting and machining.The honda 2 cylinder stator one i did some machining to
hub removal and it will be very light about 6lbs for the full assembly and
much less work to fit.
