In a circle track application oil pressure problems occur just as the driver pitches the car into the turn and plants his foot in the throttle,the accusump and pump soon equalize in pressure and during the time in the corner and coming off the corner the engine is fed oil and air. as the car hits the straight away the pump picks up oil and starts refiling the accusump as well as raising the oil pressure back up.

Hi Bill,
So the problem with the circle track is refilling the accumulator at a time when you need the pressure to the motor?? I thought the Canton systems had pressure switches that only let the system discharge when system pressure fell below the set point and then recharge when system pressure was above the set point. It would make sense the way you explained it if there was no restriction on when the accumulator refilled. Thanks for setting me straight.
