    n1 oil pump pressure?

    can anyone here tell me what the normal pressure output for the n1 pump is?

    my n1 pump is running above 120psi...lol this does not sound normal. i think the oem pump pressure is around 60psi at idle?

    its a direct reading from oil filter sandwich plate to aftermarket gauge.

    Josh's GTR with an N1 pump and R34 crank had these numbers:

    Cold start: 6.5 bars (94.27 psi)
    Warm idle: 2.5 bars (36.25)
    High rev peak: 8 bars (116 psi)

    120 seems about right depending on when you see it. Keep in mind the type of oil you use will affect the pressure. OEM and N1 pumps flow roughly the same 42-47L/min.
