Thanks to Fred, Colyn, Ron et al.
I saw the little boxes like Ron sent photos of in one other installation. I did not add these in mine, but since my temps are good so far, will not go to the trouble even though the engine is off the airplane right now. Mick Guinn did my engine install. The baffling and silicone work seemed to be very well done and probably explains the good cooling results. The scoop is indeed just that and not a blister as many have done. I don’t know if it’s better or worse, but I copied that from someone and it does seem to produce great results. See photo.
The first two photos are of the upper cowl intake mod. There is also a Word doc attached that tries to show how that was done.

Subject: [LML] Fw: pictures of baffeling mods
"I did these mods to all the outside cylinders. The pictures are not great but I also bent around the bottom of the cylinder and boxed them on the outside to prevent leakage." Ron also attached some really helpful photos. One is excellent in showing the suggested slot and deflector on cylinder 5 by the alternator as well as the kind of attention to detail required to get best use of cooling air and reduction of cooling air. Nice work that controls the air flow well. |
