Might be a good idea to pull the oil pan to see if there are any possible items going wrong.
Partial blockage? Pick up screen not positioned correctly.
Do you have an oil pressure gauge hooked up?
If so, what are the pressures, idle, WOT,turning too fast around a turn? Do you see the pressure dropping off while cornering, accelerating?
How many quarts of oil do you have in the engine?
Maybe add a half a quart of oil & try fast cornering again?
