Re: Dry sump

Just carries heat off the bearings ??? Yikes Batman I thought that was what we
were trying to do..In order to run the correct pressure you need the correct
amount of flow in gallons per minute. The flow is controlled by the bearing
clearances vs. pump size and drive speed. The pressure is controlled by the pump
bypass. The only way to reduce flow is to either make the pressure less or
tighten clearances. This seems simple at first and in a perfect world easy to
do. just make them 1/2 what they were and reduce the flow by 50%.. Unfortunately
parts distort under load and rod housing bores are not round anymore. Bearings
are made eccentric for this reason. as far as the cooling goes how long do you
think your engine will run if low on water or very low on oil at 8000 rpm??
