For some racers, 12 volts just aren’t enough.
Many drag racers and circle track racers have opted to run 16-volt batteries to give their ignition system and other components a boost. The extra voltage from these batteries creates a hotter spark, allowing you to run a larger spark plug gap and even jet up your carburetor. Combine that longer, hotter spark with increased fuel and you get improved performance.
And that’s not all.
16-volt batteries can enhance the operation of other critical race components including water pumps, fuel pumps, and trans-brakes. “Using a 16-volt battery and charging system is like adding a supercharger to an MSD box, nitrous solenoids, and trans-brake solenoids,” said Carl Pritts, an advisor in the Summit Racing technical department. “It makes them bigger, stronger, and faster.”
