Thanks for sharing your work with us. A = couple of questions though. Doesn't the TSIO-550 have 7.5:1 piston compression? If = it does, I believe John Deakin/George Braly have said the correct = multiplier for LOP power calculations is 13.7 not 14.7. Is the TSIO-550 different = in this respect than other aircraft engines? I'm not familiar with = specifics on that particular engine. I currently fly behind a TSIO-360 and use LOP settings most of the time. The 13.7 multiplier seems about right for it. = TIA Ron Laughlin Legacy 156 =20
