Ok, Ill play.

It seems that I have read about alot of wet sump issues on this board. Twisted and seized drive rods, stripped dist gears and sheared roll pins seem almost common. As dry sump pumps rarely drive off of the cam, those wouldn’t exist, thus removing a common oil system failure source.
Dry sumps pumps seem very reliable, the NASCAR guys sure spend good money on them.
They are more expensive and more complex from a plumbing standpoint. But in return they provide many benefits, Uninterrupted oil flow, actual scavenging and crankcase vacuum (without a separate pump), higher pumping efficiency, tunable pressure, increased ground clearance, greater system volume etc. In addition to the obvious performance benefits, the pump is outside the motor, service can be done without pulling the pan.
From a performance standpoint there is no comparison, dry sump wins.
Is it worth the added cost/complexity? That’s your call..
