swinn Posted November 4, 2005 Share Posted November 4, 2005 For those of you who are flying air cooled engines, I am reasearching the various cooling options for the Long-EZ. Not really intersted in the 'P-51' scoop is an option. Our Long is getting a 200HP IO 360, so we are expecting cooling to be more of a concern than usual and trying to weigh the benefits/pitfalls of each setup. The options seem to be armpit scoops, belly mounted naca scoop, or shoulder scoops. Then there is the choice of updraft or downdraft. I've heard of exhaust augmentation, but I'm not sure what that means. I have talked to the owners of two armpit scoop setups. Both of these are smaller engines, one an O-320 and the other an O-235. Both have oil cooling problems which they are still trying to work out. Both aircraft are updraft cooling. Another owner had a belly mounted NACA scoop which seemed to be working OK with his O-235. The oil cooling was reported as acceptable - this was accomplished with some extra venting in the rear of the cowl to exit the oil cooler air. I'm interested in hearing from people who are flying air cooled engines on EZ Types (Long, vari, cozy, etc...). What setup do you have and is it working? Where is your oil cooler and how are you getting air into/out of it. What type of oil cooler are you using? What temps are you seeing?
