Kelly,

That is very interesting.  I wish they had been more specific than to just
say, "high power/high rpm use".  I don't ever run over 7000 rpm, more like
6500 - 6800 rpm, then only for a short time during takeoff.  My motor is
N/A, but it is p-ported.  If my motor was boosted, or if I ran 8500 rpm or
higher, I might be concerned.  I normally cruise at about 5400 rpm.
 However, next time I have the pan off I will probably go ahead and up-size
the oil pickup tube.

Mark
