Quote: A street car on street tires? Zero oil pressure for 20 seconds after "launching" from a stop light is indicative of greater problems than just absent pan baffles....
20 seconds is a long time with no oil pressure. A windage tray is not a baffle, but it will help control slosh if you are running a pan with no baffles. Drain the oil and measure just how much you are running ( forget what the dip stick sez ). Try running an addition quart and see if the problem goes away ( don't concern yourself with foaming at this point in time ). Check the drain-back holes in the block valley area. A few more no oil pressure for 20 second passes and you will be pulling the motor for other reasons.
