TurboExec

This is in response to George asking about the "Turbo" Exec... The simple way to put it....take a stock F model and throw a turbo under the hood and a manual wastegate. Its often been said "its like having a second throttle" when you run out of one (Naturally aspirated) you start turning in the other (wastegate). I absolutely love the setup, it has been on my particular airplane since 1968. It takes away in total about 30lbs. of useful load. But the options it gives you far out weight the negatives. Nothing is changed on the engine, except some intake ducting and modifying the airbox...you lose the ram air but that is what the turbo is for. You keep the high compression pistons so you get a little better fuel economy when compared to the 235...I think the Lycoming is a better engine than the Continental anyways. Living in FL I don't use it all that often unless I am traveling some distance, or there is a really great tail wind up there. The STC certifies the airplane to 25k', I've had it up to 17.5k', and it will hit about 175 KTAS. At 6k' I'm doing 145KTAS, so it adds a good 30kts to the plane. When not in use the turbo sits idle, no exhaust gas enters the turbo when not in use....so it should be pretty good on maintenance because its not spinning all the time. With it I'm able to maintain a 800-1000fpm climb rate into the high teens. And the Mooney wing really was designed to be flown high in the thinner air...the plane really seems to like it up there. If the plane didn't have it would I pay for the STC and equipment....NO...I think it is M20Turbos that sells a similar STC and it runs over $20K (not sure if that includes install). After having the turbo I don't think I would like going without it...and about the only thing I'd like to step up to would be a TN 201. Like I said I don't want the K model due to the engine, and I don't need a long body model just yet, I like burning only 10g/hour. I don't want to start a whole LOP debate, but if I go LOP 24" 2450RPM I'll burn about 8.5gph doing ~140kts or 160mph, which works out to about 19mpg....that's better than my truck!!! If you want to know anything more just ask....And any other Turbo owners feel free to add your thoughts, suggestions, and experiences....

George you have a pm Greg....I think I've gotten all your performance charts and W&B info already

Glad to see a forums site for all of us Mooniacs....its about time. I'll tell all my mooney friends about this, and help in anyway I can...
