(ET) Battery Question

["Pestka, Dennis J" <Dennis Pestka TycoHealthcare com>]

This isn't really a tractor question, but here goes.

A fellow I work with races super stock dragsters on the weekends.
He presently runs a no alternator system with (2) 12 volt Optima Blue top
batteries in parallel.
When he races a lot and gets all the way to the finals, he notices his
batteries getting pretty weak and may not be getting the high voltage 
needed
for optimal spark.
He charges in between races, but has very little time.
He would like to upgrade and is considering several options.

Staying at 12 volt with (2) 12 volt Optima yellow tops in parallel.

Staying at 12 volt with (2) Trojan 6 volts or (1) 12 volt.

Using a higher voltage combinations, say 2 Trojans, (1) 6 volt, (1) 8 volt
in series for 14 volts.
Even higher voltage with (2) Trojan 8 volts in series for 16 volts.

He is now adding 80 pounds of ballast to get to the minimum racing weight,
so the extra weight of the Trojans should not be a problem.


I know they would have a higher amp hour rating and last longer, but would
the Trojans be able to deliver the amperage needed during the race versus
the Optimas ?

Would the G forces be a problem with the Trojan floodeds versus the Optimas
?

Any opinions ?


Thanks;
