For road racing I would have added an accumulator to begin with. We ran the 3qt systems in the past with the pressures set on the high side so that it would only fill when the oil pump was fairly close to being on the bypass. Can either run the pressures fairly high in the accumulator or go hi tech and set the EPC valve so that it will only recharge/charge at higher pressures, 40-50 psi. In that situation the oil pump bypass oil is mostly what is charging the accumulator. It basically is squirreling away oil (3qts!) for times when the engine is in an awkward position and has oil is pumped up someplace other than the pan. If you already have a remote oil filter installed most of the work is done. Best of the best without going to a dry sump for me would be the Luhn pump with a 3 qt accusump with the EPC valve. One of them we did had a rubber suction line between the pump and the pickup, and the suction screen was attached to the oil pan back on the kick out. We were having trouble on a high bank uncovering the pickup.

I probably would have added the extra quart on oil above where it is at just for a very short trial run to see if it made a difference. Then drained it out and made a decision from there. I don’t think it is a internal pressure loss issue or you would have issues with right and left corners.
