I use a 2 quart accusump with my 2270 track car. I found that the accumulator would maintain oil pressure in the middle of a corner as the oil pick up is starved but then pressure would fall dramatically after the turn. I believe once the pump sucked air it took some time for it to re-prime and then refill accusump. I have since added a deep sump which completely solves the starved pickup and now the accusump is only useful for pre-oiling. The downside to the deep sump is that it hangs low but in my opinion works much better than the accusump.
.............You , TGM, have accurately stated and explained why the accusump should be plumbed to provide ONLY pre-oiling...."the dramitically lower oil pressure after the turn"....occurs exactly(most of the time) when the throttle position is wide open, and the highest H.P. is going to be produced....Thats NOT when you want low oil pressure, (as the accusump refills itself).....A deep sump is the best solution for overcoming oil starvation.
