After the APS deeper oil pan is installed remember that when checking oil level the dip stick won't read accurately. If you fill oil up to the stock recommended level you will have over filled the crankcase.

The stick does not reach any deeper than it did before, the pan is just wider and its bottom is ever so slightly lower than the stock pan, so how would the stick's ability to read correctly be altered??? The upper surface of the oil fill (which roughly coincides with the reading on the stick, ignoring meniscus effects) will be at the same place, just more oil under the surface.

(Looks like you edited your post from the way you first had it implying oil drag would have negligible effect, but here's my response.)
I believe oil drag on the crankshaft is an issue in general. The various baffles in the VQ might keep it from being a problem except in the most extreme cases of over-filling. However, it's definitely something to be concerned with. And I'm sure APS fully explored this issue (and others) and addressed it with both their design and instructions for use.
Ever heard of dry sump conversions? Dry sumps are supposed to gain performance by reducing potential oil drag (as well as allowing the engine to be lowered for lower center of gravity).

I think I remember a mag testing a Kawasaki ZX10R that had too much oil. Drag on the crankshaft caused considerable loss of speed in the 1/4 mile. They drained the oil a bit and gained speed. Turns out there was a manufacturing problem with the sight glass or dip stick. They took it even further and gained even more speed in the 1/4.
