If your Vsupply is 14.4v you would need a alternator running 187 amps so a 200 amp alternator would be suitable depending on your Voltage loss, but this should be very small (~0.4) if your using 1 or 0 guage wiring.

Thats a big drop of voltage mate, I will advise you get a new alternator or a separate battery together with a split charger. Your voltage drop could increase your alternator current to 220 amps+. Which power cap are you using?
