My hottest CHT was number 3 at 382. The others were in the 350s and 360s. This was about 150 ROP. Just curious: What speeds do you all get at 18gph?
Danb Posted July 2, 2019 Report Posted July 2, 2019 Depends on altitude 5000 say 172-175 10,000–190+, 14,000–200, all approximate
carqwik Posted July 2, 2019 Report Posted July 2, 2019 Not all airplanes of the same model with the same engines will fly at identical speeds. At least that's what I discovered in the late 1980s when there were about 7 different 252s available for rent at a few airports in SoCal. Each one (and I flew all of them at one point) - and using the same MP/RPM settings in all - flew at different IAS roughly +/-5 kts or so. The fastest was 252YX (totally loaded - sweet airplane but someone wrecked it years later) and the slowest IIRC was 252A (which lacked built in O2 and only had a single alternator). Other tail numbers in that pool included 252MC, 252NM, 252YA, 252ZA, and 252Y. 2

irishpilot Posted August 1, 2019 Report Posted August 1, 2019 I'm also running 29"/2400, 1600 TIT in Texas and I have to trail the cowl flaps to keep mid 390s on #2 & #3. I think I have a baffles issue and will get it looked at during the annual in a few weeks. I also confirm the TAS others are getting.Fly Safe,Safety Forum Mod
