G'day, I heard recently that a guy chasing 500rwhp has blown 2 engines due to oil pump failure. The first being an N1 which fell to bits, next engine had a JUN pump that appeared to have some type of bearing failure? Is there a pump out there that'll stay alive? Besides dry sump...too pricey. I have an N1 in my new unstarted motor and want to swap pumps b4 motor goes in. Cheers.
