BrianNC Posted February 3, 2014 Report Share Posted February 3, 2014 Sorry if this has already been posted but I didn't see it. Anyone know the details of this? Should two of these be selling that low everything else being equal? http://www.controller.com/listingsdetail/aircraft-for-sale/MOONEY-M20L-PFM/1987-MOONEY-M20L-PFM/1311753.htm Quote Link to comment Share on other sites More sharing options...
AndyFromCB Posted February 3, 2014 Report Share Posted February 3, 2014 This would be a great project to put a used allison turbine on. 1 Quote Link to comment Share on other sites More sharing options...
carusoam Posted February 3, 2014 Report Share Posted February 3, 2014 Just add your own IO550 and new legs....STC MAY be required... Just be careful, the last guy that tried this was met by a hurricane in his shop... -a- Quote Link to comment Share on other sites More sharing options...
carusoam Posted February 3, 2014 Report Share Posted February 3, 2014 What's the price of a used Allison? Where do we find one or two? -a- Quote Link to comment Share on other sites More sharing options...
chrisk Posted February 3, 2014 Report Share Posted February 3, 2014 I've got to ask. What does an overhaul cost on a PFM? And what would an upgrade to a IO550 cost? Quote Link to comment Share on other sites More sharing options...
jetdriven Posted February 3, 2014 Report Share Posted February 3, 2014 Just add your own IO550 and new legs....STC MAY be required... Just be careful, the last guy that tried this was met by a hurricane in his shop... -a- But it still has the lower gross weight of the M20L, or fill the tanks and nothing in the cabin, its right at gross weight. Call it an Ovation Lite. Porsche engine is dead, those Germans abandoned suport for that thing long ago. It doesnt matter anyways, Modworks had the STC and last I heard he skipped town after a couple or three million worth of Mooneys were destroyed in his hangar and he didnt have hangarkeeper's insurance. i did read that Tim Coons may be a tower controller in Alaska these days. 1 Quote Link to comment Share on other sites More sharing options...
carusoam Posted February 3, 2014 Report Share Posted February 3, 2014 Hence the new legs and STC... I may be missing the critical details.... -a- Quote Link to comment Share on other sites More sharing options...
AndyFromCB Posted February 3, 2014 Report Share Posted February 3, 2014 Were they 14 or 24v models? Might be worth buying just for KFC150 computers at what Honeywell wants to fix one these days;-) I wish I had a parts catalog for M20L to compare pieces to M20R and M20M.

teethdoc Posted February 3, 2014 Report Share Posted February 3, 2014 Are there any STC's currently to swap those porshce engines, or are these plains only worth scrap value? Such a shame if so. Very pretty airplanes. Quote Link to comment Share on other sites More sharing options...
Guest Posted February 3, 2014 Report Share Posted February 3, 2014 I'd always thought that if you removed the engine, placed it in the experimental section and installed and Egganfellner 220hp Subaru Boxter engine you might save them from the scrap heap. Unfortunately there is no easy way to do it in Canada. Clarence Quote Link to comment Share on other sites More sharing options...
jetdriven Posted February 3, 2014 Report Share Posted February 3, 2014 No way to do it here either. That thing would go like heck with a supercharged IO-780 in it. Quote Link to comment Share on other sites More sharing options...
aviatoreb Posted February 4, 2014 Report Share Posted February 4, 2014 Didn't Rocket Engineering have a conversion to a liquid cooled continental engine for that - for the M20PFM and the M20M. I read there were only 5 converted. It had a cooling port that ran through the middle of the airplane and dumped heat in the back, and a sealed off nose. 335 horse power. It had gussets added to the weld points of the wings to raise the airframe strength to raise the Vne. It was rumored to be 10-15kts faster than the normal rocket. This is all heresy - legend of the liquid rocket. I wonder what it would take to talk rocket engineering into converting this thing? Quote Link to comment Share on other sites More sharing options...

1964-M20E Posted February 4, 2014 Report Share Posted February 4, 2014 Well if you had a spare IO550 hanging around and a cowling and mount just put it on and go. To heck with the FEDs. The end of the day why should it take an STC to put an IO550 on it's the same airframe as any other long body Mooney? Quote Link to comment Share on other sites More sharing options...
1964-M20E Posted February 4, 2014 Report Share Posted February 4, 2014 For that matter rebuild the Porsche engine yourself make what you can buy. Put any engine you like in it essentially these are experimental Mooneys anyway. Quote Link to comment Share on other sites More sharing options...
AndyFromCB Posted February 4, 2014 Report Share Posted February 4, 2014 No way to do it here either. That thing would go like heck with a supercharged IO-780 in it. And move the yoke to the center and put a passenger seat from a Challenger 601 in there for the ultimate single engine single seater...

flyingvee201 Posted February 4, 2014 Report Share Posted February 4, 2014 This model is what clinched it to me to someday own a Mooney. I that it was so sexy and slippery looking. I just cannot believe there isn't a way you can take that nice Porsche engine to a specialist of only does Porsche engines and overhaul it to better that OEM. There has to be a way!

carusoam Posted February 4, 2014 Report Share Posted February 4, 2014 ”It makes a rare bird - The Liquid Rocket 351 STC for the Mooney PFM M20L. Typical cruise of 220 kts, a service ceiling of 25,000' - there are no comparisons to be made. The liquid-cooled TSIOL-550-A3B engine produces 335 HP at 2,700 RPM. The radiator is mounted in the aft fuselage with a unique ducted system for air-flow cooling. If the need is for speed, this is the steed. Excellent IFR panel with Garmin 430W and KFC 150 with Flight DIrector. Unique, Fast and Fun. Full STC details available - call for more information."

Alan Fox Posted February 4, 2014 Report Share Posted February 4, 2014 There is an AD for valve springs I think which renders the engine scrap..... Quote Link to comment Share on other sites More sharing options...

triple8s Posted February 4, 2014 Report Share Posted February 4, 2014 IO-550g on barnstormers forsale removed from an "R" model that was next to a hangar that burned. Also there is an o2 prop on BS forsale 15 for the motor and 2500 for prop. Hmmmmmmm wife would murder me! Quote Link to comment Share on other sites More sharing options...

But there is no legal path to put that engine on the M20L, it might as well be a 450 HP Jacobs radial as far as the feds are concerned. And the STC situation makes it worse. if there is an STC to put that engine on it, you cannot do a field approval even though its been demonstrated before. They tell you to do it via STC. But you can't buy the STC. Quote Link to comment Share on other sites More sharing options...
triple8s Posted February 4, 2014 Report Share Posted February 4, 2014 Just thinking about it........they can go to the ice cap on Greenland, dig through more than 250 ft of ice, dismantle a crushed 60 year old P-38, winch it through a small hole piece by piece to the ice surface, haul it miles and miles across a glacier. Load it piece by piece on a truck, ship, then truck again. Haul everything to a hangar in Middlesboro Ky. Reconstruct/rebuild it, fly it across the US then fly it to England, and 20 years later with all our technology and increased computers and machining processes we can't even put a 550 TCM on an airframe that later came out with one at the factory. ( yes I know the gear is beefed up on the O,s and Bravo and acclaim I got that) this ain't nuclear physics, oh wait......it's dealing with the government. 2 Quote Link to comment Share on other sites More sharing options...
