High output and low revs just don't go together. Halving the rpm tends to double the size and weight. There is a reason why they invented gearing. I think maybe you need a big prop and a gearbox. Changing drive pulley size can improve alternator output a lot more easily than props and gear boxes. Another strategy is to install a high output alternator and run it at a reduced rating that still meets your needs. There has been no mention of drive belts so far. Where did you even get a pully? Nothing in the discussion to hint at one's existence. And there is. in general, no difference in weight and complexity comparing gears and belts. Casady |
