Breather box/system on high rpm engine?

[-Alex-]

What kind of breather system you have and is it working well?

I was thinking about making custom one, size about 1.5 litres. All lines AN10 from engine and drysump tank, compromise between fitting size and hose ID. Possible AN8 oil return to engine at bottom.

Should work, also two outlets at top for either 19mm or 25mm filters.
