Hi volume oil pump vs standard volume pump

AJ/FormS said

My street combo hits 66mph at 7000 in first-over. And I used to buzz her up there many times every time I took her out. And she has endured that since 1999..... with Milodon HV pump, pick-up,roadrace-pan and tray. Not bragging, just offering. Also, she used to spend a lot of time above 5500, cuz that's just my style, and cuz she lived, but mostly cuz she just sounds so good up there. Again, just offering data.
Well, she doesn't just hit 7000 at 66. I leave the line and nail it. She revs to 7000 and I keep her there for IDK 5 or 6 seconds until 65 and then shut down,usually. One time I went to the track, I kept her singing between 7000 and 7200 to 93 [email protected] seconds.Nothing broke and I drove it home. Yahoo.
Just how much oil can one of these pumps,pump, in 7.92 seconds at 7000, the whole way?

Tnx for the data point AJ.

The pertinent answer is 'waaay more than a decently clearanced engine can accept'. The real question is not how much the pumps will pump at those RPM's but how much the engine will accept at the resulting pressure into the engine? Both of these pumps will put out more than enough flow at those RPM's to force the pressure to rise to trip either the 55 or 72 psi relief valves (assuming both pump and engine are in decent shape). At that point, whatever the engine will accept at those output pressures is the flow into the engine. If that intake flow rate is less than the return flow rate, then the pan ought to continue to have adequate oil in it.

Of course, that is ignoring any tilt or slosh of the oil in the pan away from the pickup; keeping the pickup awash in oil is a factor that tends to be unknown in anecdotal reports.
