The baffle behind the engine is in deed intended to direct the air to the bottom of the cowl to be expelled. This is every bit as important as directing the air to the engine, which, is what the baffle on the aircrafts left side of the cowl does. It directs the air from the left side opening towards the engine.

No matter either way though. Crash 90 has his engine mounted, in his first post, exactly as I have mine mounted. The conclusion here is "What works for the goose will work for the gander".
