The alternator that is 80% efficient and is pushing 50A requires just 
about 1Hp.
What I've seen of the gears, unless they're made of pot metal, I don't 
see how they couldn't be stout enough.  I haven't rebuilt my engine yet, 
so I'm going off drawings (probably not to scale), and measuring the 
gear on the CAS.  I think I calculated the torque at considerably less 
than 10in.lb., but I'd have to find the napkin that I calculated that 
out on 8*)
