If you buy a generator (gas powered etc) there is only a certain amount of watts that the generator can put out. This is because the engine only has a certain power rating (and losses). However, if one were to put a higher power engine on the generator head and remove the safety breaker for amperage, you could get more power from the generator head. However, the generator head design would be underrated for this and surely can not handle it and would malfunction. What about the generator would malfunction in this scenario? In my opinion the system would overheat from the higher amperage. The cooling is not designed for this. However, is this the only problem you can think of? My thoughts are could there be some way of expanding the cooling to get a higher output generator. Specifically, setting the generator head in a bath of mineral oil. People do this to computers for cooling all of the time.
