All I've found is the same shitty scan on every forum, so I'm working on plotting it and putting it into Excel for folks to use. I'll post it here when done. However, some of the numbers are illegible. Anybody know what they are supposed to be? The efficiency islands seem to mostly start with 7, and the "horizontal" shaft speed lines look like 46100, 50599, 84019, 96255, 105547, 113083, 120203, and 1XXXXX. Ha. Perhaps knowing a pattern would help. Should they be linear? Or logarithmic? Same for the efficiency percentages. Anybody more familiar with these charts to shed light?
