Dammit I forgot to mention one other change I made when I moved all that stuff out of the pan was to use an external bypass. I’m not a fan of dumping oil (or fuel) back into the inlet side of the pump.
So I put an externally adjustable bypass in the main feed line to the distribution can. On the dyno the engine made more power up to 100 PSI. And, I put the excess oil at the front of the pan so that oil has to go past two baffles before it got back to the pickup.
The ability to control oil pressure and where the excess oil goes is a big deal at high RPM. Dumping that oil back into the inlet is a cheap way to do it.
Edit: I forgot to mention it doesn’t matter where the oil enters the system. Putting it in up front is a cleaner way to do it for external wet sump and dry sump oiling systems.
And there isn’t one SHRED of evidence that oil velocity is why the rods don’t get oil. That is completely preposterous. High pressure always goes to low pressure and the bearings are a low pressure area.
If velocity was the issue you could use a standard volume pump, or even reduce the rotor and housing height and that would fix everything. The more RPM the smaller the pump.
