Well, "double" the stock output...not quite. Approx. 80% more output. So sorry I failed to split each hair. And you mean they don't put out 130A @ idle? Duh. They don't put out 130A when the car isn't running either. Fact is that if you have a large system your current draw demand may well exceed the capabilities of your stock alternator, even at 3000+ RPM. What that means is that you'd see dimming whether the car was at idle or at highway speed. A cap will provide some extra capacitance for very brief intervals. If you run a large system and plan to bump, a cap is about as useful as a third testicle. Could you run a cap in addition to a H.O. alternator? You could but it's only going to make a difference at idle. A 20fd batcap would work better but you can buy a H.O. alt and a deep cycle battery for that much.
