Oil issues: Dry Sump, Accusump for road racing?

[Scargo]

I may have missed something, but I don't see how you can say that "clearly the 11mm pumps are not working". As I say, I have my track motor in the STi (and lots of hours on it) and a lot of friends with Subie track cars. I have that anecdotal and experiential evidence that the pump does work with cars with similar or lesser setups. It is a very "standard" pump to run in a built motor.
I'm hard-pressed to see how dry-sump affects the choice of pump.
