jnisley Posted June 8, 2014 Report Share Posted June 8, 2014 After all these years (12) I finally took our turbo-normalized Mooney M20F above 15,000' 17,800' level flight MP 24.5 (waste gate fully closed) RPM 2500 FF 11gph IAS 143MPH TAS 195MPH GS 171MPH Oil temp 194 degrees OAT 22 degrees F #1-316 1407, #2-388 1270, #3-375 1377, #4-328 1405 Quote Link to comment Share on other sites More sharing options...

jnisley Posted June 8, 2014 Author Report Share Posted June 8, 2014 I didn't take pictures but I could see Lake Erie, Lake Huron and Lake Ontario at the same time. 3 Quote Link to comment Share on other sites More sharing options...
rbridges Posted June 8, 2014 Report Share Posted June 8, 2014 What was your climb rate at that altitude? Did she have much left in her? Quote Link to comment Share on other sites More sharing options...

jnisley Posted June 8, 2014 Author Report Share Posted June 8, 2014 I kept it set at 25/25 all the way up thru 17,000, ( at 17,800 I still had 24.5mp) with fuel flow around 13.8 to keep cylinders below 385, my climb rate was around 250-350fpm @115IAS Quote Link to comment Share on other sites More sharing options...

DaV8or Posted June 9, 2014 Report Share Posted June 9, 2014 Nice! I always liked the idea of a turbo normalized Lycoming IO-360. Lower cost of operation than the Continentals. Is yours the RayJay, or the M20 unit? Has it been much mechanical headache? Quote Link to comment Share on other sites More sharing options...
jnisley Posted June 9, 2014 Author Report Share Posted June 9, 2014 It's the RayJay, installed just after leaving the factory in 1969, in the last 1100 hours we sent the turbo out once for overhaul, Approved Turbo Componants from California overhauled it for $1051.57 (2007) I'm sure for that money they didn't need to replace any major componants. It has cost us very little but we didn't use it much (flying mostly in the east) but I would expect heavy use would change that. Quote Link to comment Share on other sites More sharing options...
cliffy Posted June 9, 2014 Report Share Posted June 9, 2014 I want I want I want a TN F although my C does pretty good. Quote Link to comment Share on other sites More sharing options...
M20F Posted June 10, 2014 Report Share Posted June 10, 2014 You might want to have somebody look at your RayJay set up. I just looked back at some of my old pictures and I get 23 inches at FL210. Nice TAS though I usually top out around 165 knots as my flaps are a little hanky. Quote Link to comment Share on other sites More sharing options...
jnisley Posted June 10, 2014 Author Report Share Posted June 10, 2014 I agree, my manual indicates that "the system should provide normal sea level cruise power up through 20,000 feet." I know the waste gate is fully closing, (the cable was adjusted at last annual) it could be that there is leak in the ducting between the compressor and the inlet box.

jnisley Posted June 10, 2014 Author Report Share Posted June 10, 2014 What affect would density altitude have? Quote Link to comment Share on other sites More sharing options...
triple8s Posted June 21, 2014 Report Share Posted June 21, 2014 Would a Lyc with parallel valves be a better engine to turbocharge because of the lower compression ratio? I had a C model and always dreamed about adding a turbo and fuel injection. It would've been the perfect airplane. Quote Link to comment Share on other sites More sharing options...
