Bill,

  Sounds like you definitel= y need more outlet area and separating your radiator
=0A
and oil c= ooler inlet is a good idea also but I would do one at a time so you can=0A

My water temp ha= s been running between 199 and 217, depending on the OAT.  The oil is = pretty steady at around 175.  Today I finally got to fly with pressure= probes inside the cowling.  I was all set to try and enlarge the inle= t to the radiator to solve the problem.  It turns out that =E2=80=9Cin= =E2=80=9D is not the problem, it is =E2=80=9Cout=E2=80=9D that is the probl= em!

I have 10 inches of Hg pressure in the radiator inlet and 10 inches of= Hg on the outlet side as well as the same pressure everywhere I measured i= nside the cowl.  I need to open up the cowl some so more air can get o= ut.  I had considered a cowl flap but that would not work in this inst= ance because the problem is at cruise.  I need a permanent opening.&nb= sp; I am considering louvers and I am looking for a source.  I know so= me of you are using them.  Where did you get them and how are they ins= talled so that they look ok?
