the

with
RPM.

I was under the impression that the oil pump drive turned at 1/2 the e-shaft
rate.  When you say that the pump was run with an electric motor at 6000 RPM
crank speed, are you turning the pump drive at 3000 rpm?  I will be using
your pump drive and external reservoir on my engine ( which I just received
from Bruce Turrentine)
