The 3V oil pump are higher flow for the VVT system that starts to work at a low RPM, so I switched back to the 3V Hurricane pump and I have higher pressure now and 20 PSI at 850RPM with the cut bleeding off pressure at idle. I have run a solid backing plate before, and the oil pressure is too high running and at idle without the cut. There is a reason Ford puts all these hidden design improvements in and we see a shiny new part that is the hotter faster, lighter and we do not understand the WHY was it done that way in the first place. Don't do this.</p></blockquote><p></p>
