then you need a little more rpm to get the alternator to charge above the battery voltage. About 13.5 volts. The average alternator is now between 1,300 to 2,100 rpm. I set up an old 35 amp alternator to run off a 1/3 hp 1,750 rpm washing machine motor at a 1:1 belt ratio. Using the stock regulator would stall the 1/3hp motor. I put a large adjustable resister on the field connection of the alternator.
I got few locals that sware a stock 63 amp gm alternator takes at least 10 hp to run! And any air conditioner compressor is well over 25 hp! (both instances they are off by factors of ten or better.)  Research has shown that 9 out of 10 people enjoy participating in a group beating.  tcmtech.
