[Supras] Oil accumulator vs. pumping air

Thinking of adding an oil accumulator (1-1/2 to 3 qt.) to protect
against starvation during high speed stops and cornering at the limit.
I've already relocated the pickup as far back in the pan as it will fit,
necessitating cutting back the baffle. The baffle angle was so shallow
that from all appearances, oil would not flow back to the pickup under
hard acceleration. So under acceleration, I should be OK. Its pulling
the speed down from over 3 figures in MPH and cornering that I'm trying
to address. I've had instances in the past where cornering with another
car ran the oil up the side of the pan, evidenced by hydraulic lifters
getting noisy suddenly.
The question is this: Since, the oil pump is in good condition and will
have oil wetted gears, what is to keep it from pumping air at 60-70 PSI
during conditions at high engine speed when it becomes uncovered? Under
those conditions, the accumulator will not be of any value. Yes, air is
compressible, but it can also be pumped by a positive displacement pump
in good condition (i.e., the sump oil pump).
Really looking forward to answers to this one. Thanks.
Bernie
