Does anyone know what the average efficiency is for the ST style generators when running in the "sweet spot". The ST-3 in particular.
As I understand it, the newer design brushless 3600 rpm heads used on today's "screamers" are about 92%.
I was wondering if the ST heads fall in the same efficiency range.

Anyone ?? :o
I don't know how efficient they are. Todays brushless are probably higher efficiency. But 92%, that seems pretty high.
IIRC around 80%. My 6/1cs is rated for about 4.4kw and will put out about 3.6kw continuous.
