[Joe Boruch]

 Phil, I did not get your original email, but got a couple of the responses.  Sorry I do not have any information to help, but here is a link to TerriAnn's web site. JoeBhttp://www.tr3a.info/index.htm

Hi!
Seeking information on the torsional vibrations in the wet sleeve TR engine.  Particularly those above 6000 rpm.  Need to know the frequency of the vibrations, if anyone has any info?  Data for billet crank as well s factory crank would be helpful.
This has been discussed before, I think.  Please forgive the repetition, as I don't know how to access prior messages.  TerriAnn has some info, but I can't seem to access the homepage.
Thanks, Amici!
