Can it be done, and if so, how do you do it? Thinking of running a 16v battery on my car for better starts, how does this work with an alternator? Do I need a 16v alternator?
I have done this on my Turbo Buick. GM alternators are easy to modify for 16 volt systems. It will actually need to charge at about 19.5 volts(about 2.45 volts per cell). The major benefits are hotter ignition, and more importantly electric fuel pump output goes up dramatically. On a high HP fuel injected car its far more beneficial since fuel pump output at high pressures are hard to achieve under high boosted applications. I used a Rock racing battery that had a 3rd 12v lug for some stuff I didn't want on the 16 volt side.
