The loss is called windage. You got oil whipping around with the crank as it is spinning. The oil puts a drag on the crank. When you eliminate the oil whipping. You pick up hp. Couple of ways you can do it. Use a deep sump oil pan, windage tray, deep sump oil pan with a windage tray, or a dry sump. Listed from the least to the most efficient.
