dd, why would you say that? it's not much power gained from an alternator but sometimes every little bit counts. One trick intead of changeing the alternator is to use a larger pulley on it so it draws less current and hence not putting as much resistance on the engine.
I thought a alternator Produced current rather than drew current? The load created by the alternator is as a result of the current drawn by the engine and other electrical components (ie headlights, thermo, ect).
Wouldn't a larger pulley be used to reduce the alternator revs in a high rev motor, similar to reducing cavitaion in a water pump?
Could you actually increase power in this way? I would have thought the alternator would only cause power loss under load, whereby a larger wheel will make it harder to turn.
Can anyone confirm or dispute this?
