8V battery upgrade on tractor, 14V on race car?

I can't find much discussion on the 14 volt batteries (XS makes a couple) Looks like most racers upgrade to the 16v systems from 12v.
Do ya'll think the 14 volt is a good upgrade/compromise ?

Alternator is an East Coast mini. Engine mgt syst is Mopar (AEM) computer and they recommend up to 14.8 volts.

We were putting a battery on our 1938 Allis Chambers 6v tractor, I found out it is (was) common for farmers to use an extra cell 8v upgrade(I had never heard of) and that's what we used-works great!

Thanks, MWNorris
