Has anyone installed air deflectors in front of the front cylinders similar to the Cessna 150 to direct more air above engine and down through back cylinders? Does it help cool rear cylinders?
Thanks

Re: Rear cylinder cooling
From the old Lucas Emmett STC (pre-Randy Thompson) for the 0-200.
I can tell you that when I ran Continental cylinders the #2 ran too cool. Running new Superiors after my major the #2 runs hot, at least on climb out. The 337 I have says these came from a C90 installation. I have seen other iterations that look similar. My Superiors are slowly running less hot after about 150 hours which I'm told by some is sometimes what happens.
140's on the field here there is a C85 sans extra front baffles, and a C90 with the extra baffles.
