Thread: Racing Battery?

Tweet

I use optima red top... Lots of guys run yellow top especially those without alternators. I often put a jump box on the batt to charge it up a little between rounds (usually just once on a race day) if I notice volts at idle on the low side. Many racers use a charger after every round but then you need to mess with a generator or find an outlet. I would also suspect the starter or quality of the connections especially grounds both at the motor and the battery.. When hot all are less efficient from higher resistance

How much initial timing are you running? If it does not retard at cranking speed it will be hard to crank against the ignition like the others have already mentioned.

I also think you have more going on than just a weak battery. Is your battery in the trunk? What size/ type of battery cables? Where does your ground cable go? What kind of starter are you running....stock or hi performance gear reduction? The thing that makes me wonder is how it dies just after one run. With the proper set up you should be able to crank it time after time. There is more we need to know.

You need the fattest cables you can get, something like 0 or 2 gauge, with both cables running right to the starter.
