The dry sump is better, period. Twice I've run at Drag Week with the big SOHC and the dry sump. Both times after the multiple passes and a thousand miles of street driving during the event, I pulled the pan and nearly all of the graphite coating was still on the rod bearings. Prior to the dry sump, the same combination would come apart and the bearings would look fine, but the graphite coating was mostly gone. With the normal pan and pump the engine ran fine and had lots of oil pressure, and I doubt if the bearing clearances had increased in any measurable way, but the dry sump results after the same treatment was eye opening. You don't get the oil pressure drop with the dry sump, and the oil isn't aerated, and it really shows.
Is it worth the extra expense and hassle? I don't know, but it is definitely an improvement over the wet sump systems I've used...
