I've settled on running my Dailey pump at 90+% which is the next step up from 75%, the 75% was a tad low at the idle for some reason (engine builder I would guess), and I was under the impression for the air/
oil separator to work it needed so much rpm, which the 90+% ratio would provide at the lower running rpm's, so let'er spin. It's a neat pump, you can also change the size of the internal pressure gear, and the tolerances are very close on the inside and what he uses for bearings is interesting. Nice stuff and a great guy to work with.
