Lynn,  I would appreciate  your advice.  I am starting out to build wedge oil pans and wonder about the advisability of having a windage tray at all since they are not used stock 13-B or Renesis.   The Renesis oil pan has a sub floor about .75 inches above the actual real bottom  where oil can be trapped and presumably de-frothed.   This might only be necessary because the pan is so shallow.  I don't know and am looking forward to hearing your comments.   The wedge oil pans would be much deeper toward rear and that is where I hope to place the pick up.    Thanks,  jerry
