The Accusump system really looks interesting.
The only thing, I am thinking about, is that the volume is a little bit limited.
As I understand the US units, their biggest unit stores only about 3 litres of oil.
I have no real knowledge about this topic, but this sounds a little bit tiny for our 7 litre V8 .
The oil storage of a dry sump, which would fit to our engine, would contain about 16 litres of oil.
