Calculating oil pump requirements

Joe--- I was told by a friend who is a mechanical engineer that the way an engineer calculates an engines requirements is to find the total surface area in the engine that needs to be lubricated , the thickness of the film you want, the replenishing rate you will need to maintain a cool steady supply of lubricant usually measured in GPM(gallons per minute)-- you then need to calculate the space need for the pump and the area ofthe pan. Its a complex set of calcu;ations--- quite simply I would call Tech @ Serdi/Peterson/Weaver see what these guys say--- Generally the amount of pressure in a hot engine with hot oil at idle should be sufficient to lubricate a drag engine at speeds less than about 8500 rpm----FED 387
