Thanks for feedback. I already have a 160 on hand which is why I was asking whether the airframe benefits from the additional boost. I'm not interested in trying to maximize speed out of the plane. I'm happy with 1000' verticals, which I was hoping a 160 could do. I once had a Skymaster Viper with a P200 and had to fly that plane at half power to prevent flutter. I eventually replaced the 200 with a 160 and was very happy with the performance.
