Bob Posted November 3, 2015 Report Posted November 3, 2015 I am sure you can find owner manufactured valve springs that are already available, on the shelf. It would not take long to figure out. But the cost every 500 would be crazy. Also I believe that their is only one A&P in the US that has been trained by the Porsche factory to service these engines. Not sure an A&P that was never trained on the engine could touch it? I bet the gear reduction parts would be the real challenge! Quote
Shadrach Posted November 3, 2015 Report Posted November 3, 2015 (edited) Maintenance and proficiency flights are allowed, and there is a grey area there. If I had a T6 I'd be content doing flights like that for fun, but with a Mooney it is a different story. If I couldn't travel on a whim in a Mooney, I wouldn't want to have it. Sent from my iPad using Tapatalk Interesting. One of the T6 guys on my field plays stand up bass in a jazz band. I've seen him depart with the Bass riding in the rear seat for gigs. Perhaps it's a normal category aircraft. Edited November 3, 2015 by Shadrach Quote
KSMooniac Posted November 3, 2015 Report Posted November 3, 2015 Well, like I said, there is a grey area. I suspect he would not want to be ramped at a distant airport removing a bass from the back of a T-6. I highly doubt it is a normal category aircraft since these were never civil aircraft to begin with, and thus didn't meet CAR standards. Quote
Alan Fox Posted November 3, 2015 Report Posted November 3, 2015 If I am not mistaken , Porsche bought them back and cancelled the Type certificate for the powerplant...... Quote
Shadrach Posted November 3, 2015 Report Posted November 3, 2015 Indeed it was canceled just 6 years ago. Quote
aviatoreb Posted November 3, 2015 Report Posted November 3, 2015 I was surprised that I actually was allowed what would seem impossible these days - a one-off field approval for a 4 blade prop on my mooney. So...why not a whole engine? Maybe one could get a field approval to hang a continental on that pfm, either to mimic the continental conversion that used to be done to them, or perhaps the liquid cool to mimic the liquid rocket?

KSMooniac Posted November 3, 2015 Report Posted November 3, 2015 A field approval is a feasible way to go, but you still need to provide substantiation data to the FAA to earn the approval. Depending on the FSDO, it may or may not equate to a large amount of work, and of course the FAA is prone to simply saying NO much of the time since they have no metrics for their jobs that depend on such things, but lots of downside.

Right - I was suggesting there are two different conversions of the PFM that perhaps such a substantiation could rely on. Really, its all theoretical. It would surely cost more to do such a thing to a PFM than to just dump it and buy another airplane. Quote
Raptor05121 Posted November 4, 2015 Report Posted November 4, 2015 This is sad. I think the M20L is a feat of engineering genius. FADEC before its time. Simple start and stop engine operations. Quiet as heck, too. She is simply one of my favorite models and its a shame they still cant be flown. Quote
Awful_Charlie Posted November 4, 2015 Report Posted November 4, 2015 I'm not sure, but have a feeling the L had a lousy useful load, and the TSIOL suffered from it too - anyone know some numbers? 1 Quote
Openwheeler3 Posted November 4, 2015 Report Posted November 4, 2015 As far as the valve springs go, are they different from the thousands of 3.2 liter 911s that are out there? I thought the PFM engine was a conversion of the car engine. Plenty of those valve springs lying around brand new. Yes I'm ignoring the fact that they wouldn't have the magic aviation part number that is allowed on the aircraft. Quote

A T6 is a certified aircraft , it is not experimental or exhibition category , you can pretty much do as yo wish with it , The Harvard (Canadian version ) is not a normal category aircraft , because of this the T6 is worth about three times what the Harvard is worth.....They are essentially the same aircraft....

Really??? If they are essentially the same aircraft,,,.. Would that Not mean that they are essentially the same aircrafts... I mean,, really, I cant help myself now,,, but are they same ones,, or are they really two ones??? Quote
Shadrach Posted November 4, 2015 Report Posted November 4, 2015 Aircraft is to deer as aircrafts is to deers. As in Shrimp vs Shrimps... MPG are the you ESL? Quote
M20F Posted November 4, 2015 Report Posted November 4, 2015 The simple answer is you can do anything you want given time and money (see Bill Gates 959 law), really just a question of why. Certainly know logical reason to buy a M20L and do anything with it, but then again why does somebody like John Breda put more money into a F than what an Acclaim probably costs. Live your dreams!

testwest Posted November 4, 2015 Report Posted November 4, 2015 Absent economic justification, if I were going to do an engine mod with this, it would be to put in a Lycoming IO-540-S1A5 (high compression) and the turbonormalizing and intercooling from a 601P Aerostar. There are two decent used FWF engines from a salvage AEST on the Aerostar Owners forum for what appears to be $27k outright. About 277-280 hp as installed, but hold full power to the flight levels. 3 Quote
