The one exception might be electric radiator fans . ......Most are designed primarily for street use .
I've seen a few cars that have had fan motor failures . ...a dropping resister or module takes care of the problem .

Forgot about fans. I have had to replace the motors in my factory fans. They sure do spin up on 16. LOL

Anybody else having to buy new 16 volt batteries every season?

Ed: I have only used the Turbo Start brand of 16 v batts. I went 6 years or better with the big batts., changed to the lite weights after cause I felt guilty. The Moroso charger, maybe, was the key, don't know. I will be buying new Turbo Starts for my next racecar soon.

I have 2 16 volt Xcess (spelling ?) in it now. Not light weights. The 2 Turbostarts that failed last season. A DSR charger.

Maybe these will go another year. This DSR charger supposedly goes into a "maintainer" mode. Hope it does.

One thing to consider about a 16 volt setup is availability. You need a backup plan.

My son manages an Interstate Battery dealership and they can get, but do not stock 16 volt batteries.

It is not usual for him to get a desperate call from a racer whose 16 volt battery has failed, they need one to go to the races and cannot find one locally.

As long as you have a 12v charger in your trailer you can always put a 12V battery in the car as a back up plan. I always have a 12 v charger for the trailer battery. Nothing changes when you go back to 12 v. except the starter will crank slower and the car might slow just a bit. My car was consistently faster when I made the switch to 16v

A fuel injected car (at least mine) will run leaner if a 16 volt battery is replaced with 12 volts. The injectors open faster on 16, meaning they are fully open longer. When I went to 16 volts, I had to lean it down. Went back to 12 once, had to fatten it back up. Right now, I can not remember the percentages.
