I find 0.0015 on a std size crank at 7000 rpm hard to swallow . but!! you learn something new every day.even in my dry sump motors i build i have never gotten away with less than 0.0023 to 0.0025 with a std diameter external balanced crank at 7600 rpm with carillo rods and 50 lbs oil presure.Maybe i just not that good.
