Ok, same as your earlier post so my analysis is valid I believe.
I appreciate you looking at that again. Since those moments of "stumble" lasted only about a second, and only 2 times, and I cannot recreate it, I am fine with proceeding testing.
My (main) challenge now is getting the right pitch on the prop, and probably put a cooler on the gearbox.
As I get up to altitude, anything about 5-6k altitude the engine creeps up as the turbo holds 30". rough numbers are that the engine is at about 4100rom at 30" of MAP MSL. But at 7k altitude it is 5000rpm at 30"map. While the engine is happy at that rpm, the gearbox is not. The gearbox hold 180F until I get past about 4300rpm (depending on OAT).
Plus I have a real nasty oil leak somewhere and I cant figure it out.
....but the plane is a blast to fly and the engine runs great. From my humble opinion I like how the turbo comes on strong at about 3800rpm. It sees to be great holding 30'-35" MAP. in fact it feels like there is a lot more power after that, but I have not ever pushed it past 37" and I don't plan to and don't need to. I just to get more prop pitch and an oil cooler on the gearbox.
Sorry for repeating myself. Just trying to explain the situation.
Thanks to all the support!!!
