16-Volt Guide: 6 Things You Should Know About 16-Volt Batteries



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.”

Quick Tech: Tips for Choosing and Installing an Alternator

There are many factors to consider when purchasing an alternator.

Things like amperage, voltage, pulley ratio, and wiring all come into play. We’ve covered some of these topics in this earlier post; however, we still receive many questions about alternators from readers. So we teamed up with the tech experts at Summit Racing to get answers for some of the most common questions:

  • Why would I need to upgrade my alternator?
  • What aftermarket options are available?
  • What is a regulator and what’s the difference between internal vs. external?
  • How much wiring is involved?
  • How do I calculate pulley ratio and why is it important?

Check out the video below for those answers and more. We’ve also included some helpful charts, guides, and formulas below the video to help you figure out your required alternator output, wire gauge size, and overall alternator efficiency.
