The variable I don't have on this engine is what the system pressure would be, if the PRV was entirely closed, with an oil viscosity of @ 8 cSt. (that's the most probably cST of an oil at race temp).

I'm pretty sure the pump without any regulation is capable or producing >80psi of system pressure at that viscosity but I cannot confirm. This would be confirmed if shimming the PRV had any affect on increasing pressure. If it does then we can conclude that the pump itself is more than adequate.
