[QUOTE="bigbang, post: 3221654, member: 576408"] Would you rather tie a steel rope around your neck or a rubber one? I still believe a cap is a good idea because if you look at a graph of voltage from your battery measured acoss fractions of a second, the graph with an inline capacitor will be smoother with smaller peaks and valleys. Linear everything is the way to go. Even with a 250amp alternator, 0 gauge, and multiple low resistance deep cycle batteries, the cap still has the lowest ESR equivalent series resistance and smooths out voltage demands and gives the amp power a fraction of a second before the upgraded electric system will. A battery relies on a chemical reaction which takes longer than a capacitor releasing power stored in foil and electrolyte, and even with the beefed up alternator, the power has to travel through 15 feet of wire to get to the trunk. Even without an upgraded electric system, I think it is better for the longevity of all the cars electric systems and CPU's if the voltage doesnt jerk around so much. It will still dip low, but its like getting hit with a rubber mallet in the head repeatedly vs a sledgehammer. In the end the stock battery and alternator will die, but not as fast. [/QUOTE]
