DaveThere is the RX-8 flexwheel holes size and location the flexplate
   thickness is .080"also sketch to adapt the Tracy damper to the RX-8 with
 a
   .090 4130 steel plate

  Jean,  I think you have it there...  that should work very well.  Easy to
  make and install too!  It will move the damper plate .090 closer the the
  gear box, but that should not be a big problem.   Well done!  I will send
 it
  to Tracy giving you credit and see what he thinks.

  BTW, do you know the weight of the RX-8 flex plate?

                DavidIt weight exactly 5 pounds by the way if you need mine
 for rush work and then you can replace it when you find one, for now if i
 need measurements for my prop drive design and stator i can take it on my
 other engine, I am offering to you to save you  time  let me know. Milo I
 beefy up the Evinrude flywheel with carbon fiber and i will send it to you
 for machining this week with a sketch, you see i do design for both stators
 Honda and The Evinrude and will see which one is the best and also the
 availibility it's a question.The Honda one are not been produce anymore but
 it still lot of CB400T again on the road and part can be found true
 EBAY.COMM around the world and it look the one who is the easyest to adapt
 and lighter,no balancing required, the spark output is 10,000 volts

 Thanks Jean,

 I can get one from Mazdatrix in a couple of days if I decide to go that way.

The price is good at $159 from Mazdatrix. No bad holes either. I would make a new damper to fit. Is the ring gear the right diameter?

BTW Dave we are building a tool to punch out silicone washers from 1/4 inch
thick 70 durometer. How thick is Tracy's rubber bushing? How many washers
do we need?

I think the the durometer is a bit lower so the chatter RPM should
drop 100 RPM or so from about 1800.

The silicone rubber is a bit expensive at McMaster Carr.

Here is your OD and ID.
ID  (OD of the center plug) .752
OD (ID of the hole in the plate)1.355
