Paul & Group,

What are the latest thoughts on using a windage tray on the oil
pan for
a Renesis?  Good?...Bad? Construction technique?

I don't really think they are a windage tray. More of an air
oil separator tray. The RX8 (Renesis) engine has its oil vapor
problems but  they can be fixed by building  a deeper custom oil pan.
If you add a gallon while you at it your oil cooling problems on
take off will be reduced as it takes longer to heat the
oil mass.
