Tom,

=C2= =A0 To my knowledge Stuart is not on this forum.........His PSRU's have= been principally been used on=C2=A0
Chevrolet V8 and Subaru engi= nes.......The version to be adapted to the Rotary is basically the same=C2= =A0
as that used on the Subaru (With ratios appropriate for the R= otary) and a different harmonic damper...
=C2=A0 Time will tell i= f his PSRU works for the rotary...........<:)
