It will, an Accusump is for exactly that purpose. It will supply oil momentarily when pressure drops, but not for extended periods.I just installed the pan. I checked the trap doors by hand... they're all fully functional. I also put about 7 quarts of oil in the engine (~6qts for the pan, and some for the filter), and the dipstick reads full.
I'm wondering whether the trap doors work great while under consistent high Gs, but not so well during unloading... although I'm not sure that 1/6 second with low/no oil pressure is likely to be a highly consequential... (I hope not anyway...)
EDIT: My next mod was going to be an Accusump... but I'm not sure an Accusump could respond to a 1/6 second transient anyway...
