Guys.
I had a flight of 55 min tonight and I used full throttle and set
the leaning out the highest exhaust temp to 1370. In the past when I got
this high it would be close to acting up and shuting down. this time the
other temps went to a 40 deg. span and 3 of the exhaust temps were as
close as 2 or 3 deg. the other 2 were about 10 deg off. The middle left
cylinder(#4) was the coldest through out all the testing so far.
I am going to try to find where the peak lean is next.
Another problem that does not exist anymore is when a rapid
decrease in throttle was done I would get stumbling and rough engine
that is not happening now.
Some of the operational numbers from tonight are
3380 rpm
oil temp 210 deg
altitude 3500 to 4500 ft.
#1 1344 deg
#2 1352
#3 1354
#4 1332
#5 1351
#6 1370
cylinder head temps mirrored the exhaust temps for each but in the range
of 280 to 310 deg.
The out side air was 44 to 46 deg. This brought my oil temps up
tonight as I have the cooled almost completely blocked off for winter.
Oh yea. The total fuel burn was 4.5 gal. and true airspeed was
173. 3 as checked tonight.
This is the most in control of the engines operation that I have ever
felt. So far so good for the Tornado intake devise.
