The M96 engine is not dry sump. The owner's manual says "integrated dry sump" i.e. wet sump. On the track, especially in prolonged high-G loading with sticky tires, it's common to have oil starvation, leading to spun rod bearings.

Use of an accusump isn't anything new. Porsche 356 guys (and 944, etc. anything with a wet sump), have been using them to prevent oil starvation on the track. The accusump is an oil accumulator, storing some volume of oil at pressure to be released as engine oil pressure drops, preventing or at least prolonging an oil starvation event.
