Bite the bullet & go dry sump, I have seen videos of some tracks in your area & they are fairly 'busy', lots of rise & fall, long sweepers & not a lot of camber... An accusump might not get time to refill/recharge in between points where the wet sump is picking up air & that can lead to the accusump being recharged with an aeriated oil mix & since the time frame is short, that is what gets fed straight back to your motor...

Dry Sump, .... looks like you have a world products block, has that got priority oiling?, if so when you fit up the dry sump, split the outlet from your remote filter & plumb it into both front & rear fittings...... Oh and check your crank for a bend, not often you get away with that much heat without tweaking the crank, especially since you kept on driving with the bearing toasted.
