Do I need a hardened intermediate shaft for a HV oil pump?

I concede To the geater minds on here. Dose it require more effort to pump a geater volume at a given pressure..Yes... Can you pump a pan dry..yes... If I was building a new engine with perfect clearances on the tight side I would use a standard volume pump with the hardend shaft just for a little extra safety but in my experience the stock piece works fine up to 70 psi with a high volume pump.
Now on the pumping the pan dry deal. if you are sustaining high rpms long enough to pump the pan dry you need to look at the oil return path because something is restricting the drain back. Adding volume to the oil pan will just delay the time it takes to empty the pan slightly.
