OK Guys
I've been going through a lot of old notes and trying to get stuff sorted and organized when I came across this info from some of my datalogs.
It is the difference of airflow between the stock 60mm tb and a 65mm tb with no changes other that the larger tb being installed.
Other than the diference in air flow, I know nothing about how much gain that additional airflow might be.
The data you see here is one data event from two different dlogs for each tb. The values hold pretty tight between each dlog so I think this stuff is valid for comparison.
Anyway, since we do have some brain trust peeps on this site, I thought maybe one of them might see this info and could convert the additional air flow to a ball park gain of some sorts.
dlog# tb rpm kg/hr af ratio
1800 60 5800 778 12.43
2158 60 5950 780 12.46
1929 65 5850 805 12.33
2254 65 5950 805 12.49
