They also have a thing called AccuSump that is a hydralic pressure accumulator. It goes in the oil line on the pressure side of the pump. If the regular sump sloshes and the pump doesn't pick anything up, the accusump keeps the pressure and the flow going. It is a pressurized reservoir. The amount of time it protects the motor is dependent on needed oil flow and the size of the accusump.

That is what some of the 928 racers were using until thy discovered the oiling problem wasn't sloshing. It was that at high rpm flow rates the heads were filling up and not draining back down to the sump quick enough. One guy even installed a sight window in the valve covers and you could watch the heads fill up at high rpms. The solution now is to improve the head oil drains to the sump. Some even put a vacuum pump in place of the smog pump and put about 6psi vacuum on the sump to suck the oil out of the heads. Others even run external drain lines from the heads to the sump.
