Hello !
I found some time this afternoon to take the Saïto T3R out of its boat and run a test !
Max 2000 rpm @ 2b only . I get 3600 rpm 3.2 b and .6 HP. Then this old engine gave up and jammed !
Below are the only numbers I could measure but I have reserves about these figures.
I don't know what you think of those numbers but I am still away from the manufacturer's one.
Need to do some tests with steam . The boiler STUART HB4 is ready !
Anyway ! That's all fun and now I have to open engine and see ....
Steam is an endless story !
I'll try with the big one later on!
Have a nice one !
