[alfa] Re: What is a windage tray

[Tom Lesko <tmlesko@xxxxxxxxxxx>]

From the Canton racing products site:

Windage
Windage is the flow of air within the crankcase.  Each time a piston
comes down in the piston bore the air under it is pushed into the crank
area and each time the piston goes up the air is pulled in behind it. .
. At the same time the rotating assembly is  spinning and churning the
air.  Oil coming off of the crank is also put into the mix. So as the
RPM increases so does windage. At 6000 RPMs the assembly is rotating
100                  times a second.

Windage trays
A windage tray keeps the windage around the crank from the oil in the
sump area. It should allow the oil coming off the crank to easily enter
the sump without the windage affecting the oil already in the sump.  A
good windage tray should also keep the oil in the sump from getting
into the rotating assembly when the action of the vehicle is in motion.
