I was given the info by Mopar Performance shop by me. I do not understand it fully myself. even though themelling pump spins faster above 3000rpm, it doesn't move any more oil thru the engine as i'm told. only thing I can figure is it creates too much internal pressure above 3000 and the pump bleed valve opens and it just dumps the excess oil? I don't know the name of this new pump, but it just keeps pumping and moving oil no matter the rpm and it does not work had at low rpm. I will know more about it next week.
