Rick, Thanks for the pictures.
Looking at the internals on the picture with the bottom oil pan cover removed, those seem to be 2 large oil pick-ups to the pump. I understand it's a dry sump engine, I wonder if us guy's running the engine in an upright position need to modify our bottom covers, as well as mod those inlets to be horizontal. They are positioned to pick up the oil with the engine lying on it's side. For those not familiar with it's original installation, in the sled, it lies down a lot, and the bottom cover is a triangular shape, the one side being the horizontal lower most oil pick-up in the sled installation. I would think, in the upright mounted position, with the pick-up now being angled, and it being a dry sump, rather than a tank of oil in the pan, there might not always be enough oil in the bottom to cover the inlet, thus making it suck air. This frothed up mixture might be a problem if the external tank does not sort out this frothed up oil by the time it returnes back into the engine.
Any comments out there?
