Now why would you drill extra holes into a Windage Tray? Have you ever started a "Remanufactured Engine" without an Oil Pan? How can you do that? With a Dry Sump Oiling System Plumbed into an Oil Scavenged Aluminum Tank! Thats how. How much oil is flying around in the pan at startup? Not as much as you would think! The extra holes help it drain away from the crank!
