    Hello Cruiser, Thanks for the info. My CHT runs higher on #3 and #5. Here is a link to my JPI plot-- https://dl.dropboxusercontent.com/u/41259646/2013-09-10%2017_28_59-JPI%20EzTrends%20-%20%5BMain%20Graph%5D.png My #1 CHT is usually 30-40 deg C cooler than my CHT #5. EGT #4 is 50 deg hotter than the rest. Masoud

    Hello Cris, Long time no talk and thanks for your help in my transition from a Cessna driver to a Mooney pilot. Your landing tips worked perfectly I think rigging is an issue on my plane since the balanced ailerons sit slightly higher than the flaps. This may cost me a few knots. I will check that in the next annual in December. I may need the 2700 rpm STC to get out of Truckee when my kids get older. My CHT runs between 370-400 deg C on a hot summer day (in 80s), full power at 8500 DA climbing at 120-130 knots. I usually climb at 700-900 feet per minute in cruise climb. My CHT is around 350 in cruise at 8000-10000 feet with 50 deg ROP. Are these comparable to your experience? Masoud

    Zane, 8000 to 10000 feet full throttle, 50-70 deg rich of peak gives me 178-180 knots. I will try the richer mixture that you mentioned (125 deg ROP) just to find out what the performance is. Most of my flights are short (1-2 hours) so I can l can live with 10 knots less and have a happier engine and fuel tank Masoud

    Spenscot, My understanding of Eagle is that it produces 244 HP at 2400 RPM. If you can go up to 2500 rpm, it is the same as my screaming eagle. At 2500 rpm on take off, I burn 22.5 gallons per hour. What is your take off fuel flow? Masoud

    I agree. The 310 HP at 2700 RPM is time limited and CHT limited. You can do 2550 rpm in cruise which may buy a couple of knots. I am fine with the 280 HP at 2500 rpm. I fly in and out of Truckee in CA where the density altitude is usually over 8000 feet in the summer (my personal limit is 8500 feet). I may consider the 310 HP STC if my kids get older and heavier! Of course, I could make up for it by losing weight

    My Eagle is a 2500 RPM Screaming Eagle producing 280 HP. Its prop can be set to do 2700 RPM which makes it a 310 HP screaming eagle after a fuel pump set-up. I saw numbers as high as 197kts in the Ovation-2 POH and 190+ in Ovation-1 POH . Perhaps it is not real! If Ovation-1 cruises at 175 kts, Eagle at lower gross weight and the same HP should do better--- which is where 180 is coming from. Ovation-2 has a two bladed prop optimized for cruise.

    My 280 HP Eagle does 180 kts at gross weight. I expect it to do 190+ since the Ovation at 280HP and higher gross weight (3200 VS 3368 for Ovation) claims to do over 190 kts. I have a HTZ three bladed prop. Can anyone shed some light on this? My climb rates are as good as the numbers in POH for Ovation.
