G'Day,
Background
I'm building up a budget gtr track car (if such a thing exists), I took it out once and did number 6 big end bearing.
I am now rebuliding it and have done all the standard fixes oil restrictor, head drain, extended sump and oil cooler. I will keep the revs down to 7800ish and just change gears to go faster (ha ha).
I am thinking of reusing my 115k oil pump (shock horror), I measured it up and the clearances seem ok.
My Question
I have read a bit on this topic and what I can work out is it seems all crank driven oil pumps (even Jun) fail due to crank vibrations/harmonics through either high revs or rev limited induced harmonics. What do you think?
If this is the case as long as I keep the revs down and don't sit on the rev limiter the standard pump (N1 pump with weaker relief spring) should be ok?
Am I mad or does this sound OK
