Less volume of oil in the crankcase = less windage = less hp to spin the crank = more overall hp
Using a extra quart oil pan with one less quart of oil helps to achieve this without loss of original intended capacity.

Not sure most performance dry sumps have like 3 stage oil pumps compared to single stage in a wet sump . you do get advantages as you pointed out with windage as it is dry now and of course main one of no starvation in high G forces .Most engines have no shortage on hp that use dry sumps (not used on many passenger cars except a few sports cars like 930 ).
I try an find the vid it was showing the differences of different oils and then running the engine low by 1 qt which on this extended pan is fine .
