Windage trays help control the movement of engine oil inside the crankcase and reduce oil contact with the rotating assembly. By separating excess oil from the spinning crankshaft and rods, windage trays help minimize parasitic drag and improve engine efficiency.
When the crankshaft rotates at high speed it can whip oil into a mist, creating resistance that reduces power and affects oil control. A properly designed windage tray helps strip oil away from the rotating assembly and direct it back into the oil pan.
Windage trays are commonly used in performance and racing engines where higher RPM and increased oil movement can impact both power output and lubrication stability.
Whether you are building a performance engine or upgrading the oiling system during a rebuild, a windage tray can help improve oil control, engine efficiency and overall reliability.
