Its not how much it pumps Its how it does it. I'm told a conventional pump kind of smashes the oil creating heat and small air bubbles and this is what they say is what burns your oil and wheres it out.A dry sump has head pressure on the pump thus eliminating the need for such tight clearances and not smashing the oil.IT will also act like a vacuum pump (less oil leaks) also by the time you buy the pump 2000.00 pan 500.00 tank 550.00 filter 150.00 plum it 1000.00 scavenge filters 40 each x? You put about 5000.00 into the economy and you can say you did your part in helping your country out of economic bad times.
