I am definetly not smart enough or have the experience to design or compare pick up designs, that is why my life is one of repetition. This pickup in this engine along with all other components in the block is identicle to my last one which had great
oil pressure. I also have the hard data from the
oil cooler testing showing zero pressure drop at 65 psig at 5500 rpm's. In the end at 4k rpm the pump is pumping the same regardless of 40 psig or 60 psig as long as the rv is not lifting. I think that is correct, who knows as my confidence is in question right now on fluid dynamics.
One option is the blue printed
oil pump which is a work of art, it would help to compensate if this is in fact an issue. But i dont like to compensate i want to understand why why why why why!!
