Type-4 Dry Sump System, Any Thoughts, Ideas, Comments? Options

[Britain Smith]

I am toying with the idea of installing a dry sump system on my turbo type-4 conversion in my 912. I have the room to mount a 911-style oil tank in the stock fender location and can run a fender mounted oil cooler up front. I also need a way to keep the turbo properly oiled. Does anyone have any experience with this? How might one plum this system up? Where can I get a dry sump pump for this purpose?

I want to explore the dry sump possibilities is to provide the turbo fresh, cool oil straight from the tank.

you'll need to provide -pressurised- oil to the turbo. it won't matter if you take this from the main oil gallery or a separate stage of a multi-stage pump.

i think the main advantage is that you can run a separate scavenge stage so that you can run a low-mounted turbo and have a way to get the frothy post-turbo oil foam back up to a place where it can de-aerate. the T-IV block is so darned short that it's hard to find a place above the oil level for the return - and then you're dumping hot oil froth into the sump with the rest of the oil.
