I would like to read Techs answer also,but I'll bet it's because the high volume/high pressure pumps rob horsepower and wear dist.drive gears, all you are doing is pumping extra oil to the top end. All ya need is 10 psi for every 1000 rpm,"just a rule of thumb" and the stock oil pump is more than capable of that.
