Regarding the alternator....

"Its pretty minimal. You can calculate it by knowing that 1 HP = 750 Watts. So for example, let's say that you are changing from a 60 amp alternator to a 200 amp alternator. That is a difference of 140 amps. Let's also assume your charging system is putting out 14 volts. Power in watts is equal to current (amps) multiplied by voltage. So, 140 amps X 14V = 1960 watts. 1960 divided by 750 is 2.61 HP. If your alternator is only 50% efficient, that's about a 5 HP difference. And the alternator is probably a lot more efficient than 50%. Plus, your 200 amp alternator is not putting out 200 amps all the time, it is only delivering that amperage when it is required."
