I have read that a "Dry Sump" is a kinda pcv replacement... the vacuum pump sucks all the blowby gases away at all rpms and the crank/rods/piston undersides all move with less air to push out of the way. This saves more horsepower at high rpm than the vacuum pump consumes.
You are confusing a crankcase evacuation system with a dry sump oiling system. Change the name in the above from "dry sump" to "crankcase evacuation system".
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
