Content-Type: text/plain; charset=us-ascii
A windage tray is a steel plate (tray) that separates the engine oil
from the crank shaft galery area.
Its purpose is to keep the oil in the pan and reduce the fan effect of
the rods and crankshaft oil as it passes used out past the bearings. It
is also said it reduces foaming, reduces oil temperatore and in the
Porsche Type IV engines keeps the oil from sloshing into your cylinders
in hard cornering.
If you have a copy of Tom Wilson's book, there is a picture on page 74 of
a Windage Tray.
