Most electronics have a range of voltage that they will work on. Not just a nominal 12 volt, but I can't seem to find specs without calling manufacturers. As already stated, there are many, and I would lean to say MOST drag racers that use 16v. With and without alternators. It also appears that 16v has become the go to for car audio competition. Car audio folks are a good mix of purpose built and daily drivers.
I know from experience with quite a few drag cars, that msd, big stuff, race pak, nitrous, and many other products including lighting, work better and virtually flawless. I'm just trying to understand/figure out why it isn't talked about much for serious street.
There is a major difference between 12 and 16 when it comes to cranking a big inch motor with big compression. Guy above obviously knows.
I do appreciate all the input, we may get to the bottom of this. Then the search function can return something useful.
