I think it would be a mistake for you to run with a Potts cooler in circuit reducing the oil temperature by this means, because we can never hope for, neither do we want a cooler of these dimensions. The first point we should like you to try is to reduce the oil pressure to 15 lbs. to see what difference this makes. | ||
