A little story like That
2 years ago I open for the third time my 4 cylinder IO360 to change broken rigs , the second time was the change of 3 cylinder probably cause by the champion spark plug ( champion paid all the cost for that 3 cylinder expense .) and the first 2 cylinder still caused by exessive heat. By this time I would operate my 1967 M20F on the advise of Bob kromer to put all in the dash in climb or 25 square under 5000 feet ,
by this time I'm opperate 26RPM(because it was little bit rough at 25) and wide open trotle 50-100 rich of peak.
It was not rare to open my cowl flapin cruise at over 9500 on the return off Florida by exemple. the oil consuption have never ever been under 1 quart for 2 hour also even with 4 new cylinder and as the green was at 450 degre and the red line at 475 deg I was not to worry to put my plane in this condition..
So after the third top in 400hour I looked for the best manner to break my piston ( because all the mecanik said different thinks about that) , so I turn my interest on Youtube and fall on this guys Mike Bush .
So I apply his very simple procedure for the break in ( wide open , lower rpm before red line , wide open , cowl flap open , under 3000feet if possible.) Itake a 2 hours fly to visit friend of mine from CSG3 -CYHM ( joliette qc to Hamilton ont) and return home at the same day . surprisely my motor take only 1 quart for 4 hour andat this time it was file.
after ,although it made me grind my teeth, I apply the lean of peak procedure 50-100 degre lean suggested Mr Bush also remembering the warning of never higher of 380 CHT , surprisly I past of 12-14 gal hour to 8.5to 7.5 gal hour , no more overheat , my oil consuption fall on 1 quarter for 5 hour and my range go sky high !!! but instead 155kt , I fall at 140-45kt. (a big deal considering the advantage) today I love my Mooney over the top since this advise.
Now the reason I tell you this story is very simple , like all the advise of this guy give to me about the break in and the operation of the Mooney I own since 20 years seem to be true, I would be inclined to believe that he is telling the truth about the advantage of the turbo!
sorry to burst your bubble
Have a great night
