Question for Leon and Lynn -
I am building a NA Peripheral Port engine that I would like to
tune for a max of 7000 RPM and 6000 RPM continuous.  Do I need
hardened statioanry gears?  Tracy's experience is that these are
not needed for 6000 RPM, but the forces involved would seem to be
much higher at 7000 RPM.

Thanks,
Ken Powell

I don't know. I think I just read somewhere that the later 13B gears were factory hardened. I never lost a stock gear, but have lost hardened ones. If you loose a rotor bearing, you should loose (get rid of)the gear on that end. The teeth won't take much weight, they just index the rotor. Leon probably knows. Lynn E. Hanover
