A 130 Amp alternator will handle those ok, but 93stang306 may have a stock 75 Amp alternator on his car and it may not supply enough power under harsh conditions.
My car has an electric fan, electric water pump & ignition. I will be adding an external booster fuel pump too, so to keep everything supplied with enough power I'll be using a 200 Amp alternator. It is a bit of overkill, but it will allow me to add other electrical components later without worrying about the power supply.
