Imo if using 12 volt battery the loss of volts, during the run, will lose as much as an alternator using hp. 16 volt bat is another thing. With all the different electrical components on the cars today that bat will go down quick. An example, run a fuel pump at 12 volt than at 11 then 10, see how much it drops off. Now add the fans-computers-data loggers-ignition and other things, keeping 13-14 volts supplied the whole run is better and far out weighs the 2-5 hp loss (depending on how fast the alt turns at speed). Furthermore setting in the staging lane for hours makes it hard to recharge your battery. I for one will never run a car without an alt.
