MB65E Posted March 25, 2020 Report Posted March 25, 2020 Just heard M20L N78MP fly over SMO at 4500ft north bound. She sounded absolutely amazing!! Even had a little crackle in the exhaust note to it. Really wish that Porsche thing could have worked out better than it did. I here airplanes all the time and this one got my attention. I couldn’t pinpoint it until I looked it up on FlightAware. -Matt 1 Quote
carusoam Posted March 26, 2020 Report Posted March 26, 2020 Would the registration reflect if the engine was swapped out along the way? (Liquid Rocket option) The current registration still lists the original engine... 217HP. https://flightaware.com/resources/registration/N78MP Best regards, -a- Quote
bfreelove Posted March 26, 2020 Report Posted March 26, 2020 I have a converted M20L and the FAA registration still shows the original engine on mine. N78MP is one of the handful that had been converted. The IO-550 does sound nice though! 1 Quote
MB65E Posted March 26, 2020 Author Report Posted March 26, 2020 What’s UP Ben!!! Sure sounded way different than any SR22 I’ve heard. take care! -Matt Quote
bfreelove Posted March 26, 2020 Report Posted March 26, 2020 Hi Matt! The Ovation exhaust on the IO-550 is better tuned then the SR22, and faster always sounds better..... -ben 2 1 Quote

Nice planes! They have a special place in Mooney history. 1 Quote

LANCECASPER Posted March 26, 2020 Report Posted March 26, 2020 Not sure how someone is keeping a Porsche Mooney airworthy. There was an AD on the valve springs requiring mandatory replacement after so many hours and Porsche stopped supporting it so no parts available. Maybe someone has a stockpile of them (or they are using supposedly the same valve springs that a 911 uses) Quote
carusoam Posted March 27, 2020 Report Posted March 27, 2020 Owner supplied parts would have been a great opportunity for supporting the Porsche engine... The Liquid Rocket has 350HP... The Porsche engined M20L, was the first Long Body... 217HP is a bit low when loading the plane... The L is a great way to add volume, compared to the J... The next Long Body got the more stout legs... M20M. I like the IO550... Missile, PFM, Eagle, Ovation.... anyway you can... Best regards, -a- Quote
