I have one of these installed in my Bug engine when I did the engine mods.
It was advertised to keep prevent oil starvation during hard cornering...I suspect a potential problem for circle-track cars.
For the most part, going to a deep sump eliminated this issue for race cars (and I got one for the Bug as well), but for production vehicles, the windage tray is still the simplest solution
