I am sure that you are all aware of the benefit of running a 16V system over a 12V system. I regret to say that it took me until last week to finally make the change to 16V. Since we do not run an alternator we were running (2) 12V batteries and replaced this with (1) 16V battery. We noticed a performance improvement of 7.78 to 7.64 in the 1/4 mile and we also gained 3 mph. So I guess that was a very cheap ($700.00 for battery and charger) way to gain .14 seconds overall.
