Guys,
     Just gimme a drawing or 3D model of mazda rotor and I'll do all FEA
    (it's fairly simple and I have ANSYS, NASTRAN/PATRAN, ABAQUS at my disposal)
    and the rest. I just don't have time to fiddle with equation driven curves.
    If one will send me a rotor (I will send halfs of it back) I will simply 3D
scan
    it and make 3D model myself.
     Rob - would you email that paper to me please? nevaracing @ mail.ru
    Here some very tricky parts are made out of Ti alloys... It's not simple
    and very cheap but it is doable.
     I'm not saying that steel is worse than Ti or other way around. To
     me
    it's just a matter of material and technology available.

     Thank You
     Ted

    OK Ted send me your mailing address by email and I will keep it private.
    I'll send you a rotor. I don't need it back. Just take some digital
    pictures
    of it after you cut it in half. And the stp file from Solid Works.

Guys,

The nasa file is 20Meg and i cannot send it over email. I could send it
to you through IM in about 3 minutes if you have an address you want to
give me. Other wise you will just have to deal with this copy and paste.

I understand ti can be worked with but in this case I think it is above
and beyond just welding stuff together. Weld it and you'll have to heat
treat it which brings up all sorts of problems. Cast it and the same.
The few drawbacks that it has are large ones.

Also in this paper they were getting a reliable .375 BFSC and they had
realistic plans to get it down to .3

Rob,

I am searching for some used Renesis rotors right now as well in Japan.
I'll let you know what I find out.

Doug in Japan.

Used RX-8 rotors are starting to show up - even on Ebay.  They are at a
bit of premium.
A damaged set for dissection should be easier to come by.
Try rx7club.com, rx8club.com, nopistons.com.  The mazdatrix guys or
other shops as well.
The incremental improvement over the S5/6 NA rotors is most likely
marginal/debatable from what
I have heard/read so far.
