jetdriven Posted March 13, 2013 Report Posted March 13, 2013 Part of the reason cowl flaps cool is they create low pressure behind them when open, and pull air through the cowling. Look at a J model sometime, they boxed the underside of them in to have sides on them to help increase the low pressure. E models are simply a flap with a stiffener. Air spills in the sides and negates some of the benefit. One of Kromer's Mooney articles taught me that. Quote
Oscar Avalle Posted March 13, 2013 Report Posted March 13, 2013 I did not remove mine, but I opened them and it made a difference in my M20C with fixed cowlflaps. Quote
