A shimmed oil pump with a decent oil pan and baffle setup will work, we use that very setup.
I think if the Subaru team had to endure high rpms with the g's you see on track they would use a dry sump but based on most usable power being well south of 6k on their cars I can imagine there is no gain to using the dry sump.
They do run a pretty trick oil pan setup due in part to ground clearance and the setup of the manifold they use (I have one here and it's sick!)
