Nice plane! Air is a much cheaper coolant than fuel. After break-in, with those tight CHTs you’ll save 5 gallons per hour by going LOP to the loss of about 5 kts. My Velocity (N36LV) had that engine, admittedly with one Lightspeed electronic module and one mag, but I always did Mike Busch’s “big pull” right back to 50 degrees LOP in cruise. 195kts day-in and day-out on 13.5 gph. That is truly a lovely engine to fly behind. Only one drawback: the “seventh cylinder syndrome”. The alternator resides where a seventh cylinder would be and is subjected to a lot of vibration. It work-hardens the alternator brush connecting wires which then fray and short to ground. I just replaced them at 50 hr intervals and the problem was solved. Happy flying!
that was interesting and fun to watch
Nice video Paul. You are getting better at this every time. Have you added a couple of cameras? I like the little logo at the bottom, nice touch.
Thanks Cruzer! I use 4 cameras. The newest GoPro (Hero 8) often overheats and shuts down after 30 minutes. Then i at least have three others as backup.
Great video. Thanks for sharing!
Thanks for watching!
Any discussion with the people that did the Dino testing whether that extra 30hp is constant? In other words, is it recommended to go full power on climb-out to a safe altitude and then power back for the remaining ascent to cruise altitude? So that extra 30hp is....if you are familiar with the movie Spinal Tap...where they have a "volume 11" on their amplifiers, when they need that "extra little push over the cliff". I know on a P-ponk conversion they convert a 230hp 470 to around 275hp but it is not for sustained or cruise applications, only for short climb-out use. The P-pink conversion is also a piston and cylinder conversion so it's quite extensive and maybe not relative to your upgrade. Anyway, thanks for sharing, excellent video.
Hi Crosscut, 30 HP was expected and typical for this engine after the procedure. Yes, know about the amp that goes to eleven (ha ha, classic movie) but that’s not the case here - since i can feel the extra power, mostly during takeoff.
Is the restricted area Fort Hunter Ligget?
Yep!
