·As the crankshaft rotates while the engine is running, the counterwieghts and throws skim the surface of oil in the pan, and at times pick up oil as they rise. This causes drag on the crankshaft,(imagine moving your hand through water), and slows down the rotation. A windage tray is a baffle which removes the oil from the crankshaft as it rotates. This prevents the oil from clinging to the rotating assembly and removes the drag, increasing the possible acceleration rate and horsepower output.
