what would you have to do to get a total of 16 volts

I have a good 12 volt battery in the trunk couldnt I get a small kids battery like out of a little trunk that had only 4.5 volts and hook it up in line to make 16.5 volts?
How would I hook itup to make that or would that even work?
We cant run a alternator and no 16 volt batterys or 14.4 batterys

can remember who but someone had a diagram on how to hook up a 6 volt motorcycle battery in line with a 12 volt and run at 18 volts.

Maybe someone will post it for you or you might be able to do a search for it.

Sleepy Gomez did the article in Circle Track about the 18v system using the 6v motor cycle battery. He also mentioned in that article that he had also used some different types of batteries to accomplish this. You might want to shoot the question to him since he is a registered member of the forum.

For 18 volts run your hot wire into the negative side of a 6 volt battery and run a wire from the positive side to the to the ignition. Make sure your toggle swithch is between the distributor and 18v source so that that all power is shut off from the distributor when not running. I would think it would work the same way with the 4.5v battery.

Why would you want to do this anyway?

Just go buy a 16volt battery.

The reason for doing this is cause a HEI system needs 13 to 14 volts to run at its optimun if you dont think that it runs as good with a 12 volt battery verses a 14.4 or 16 volt battery take your battery charger hook it up start it then run it with it hooked up and un hook it while its running and you can here the change

As to the question as to go buy one or not
We cant cause they check for 14.4 and 16 volt batterys
BUT why I cant hide a little battery under the dash where they cant see it

Sleepy Gomez is the tech editor for Stock Car Racing not circle track. I don't know about here but his e-mail is at the end of his articles.

Beware this only applies to using the igniton module. If your using a MSD, it takes place of the module.

Can you just install the 16 volt battery what about the tach and other things that are 12 volts?

Autometer say's the 16 volt systems won't affect the pointer but the back lighting may be to bright. Guages are the same way.

Ran 16volts for years no light problems.

I was going to point out that you should double check your rules, most rules state "One 12-volt passenger car battery only", but you know that.--"under the dash where they canít see it"
In sleepys article he mentioned using lap-top batteries for less weight due to their small size. This may be the thing you need. I believe they were 2 volts a piece and he used three.
Does anybody remember what issue that was in?

One 12-volt passenger car battery only" Thats a gray area there it says you can only run one 12 volt, but it doesn't say anything about running a 6 volt along with it. I run a full size 12 and 6 volt and I'm completely legal.

that is what is wrong in alot of classes,
everybody wants to use their interpretation
of the rules, instead of following them as
they are written. it says one !!!! 12v battery only, not one 12v and one 6v an one
3.456v.

I know MSD makes a converter for their boxes that put out 16-18 volts. No batteries to mess with and it probably isn't in even in the rules, because its an converter it follows the 1 battery rule. I seen it in speedways web site.

The rules are screwed at our track anyways, the rules say a factory stock torque converter which means that you can run a hollow converter because it doesn't say unaltered. Thats the promoters words not mine. I have ONE 12 volt battery not 2 not 3 just ONE how is that illegal?? If the rules say nothing about a beadlock being illegal does that mean I shouldn't run one?

I know at the end of our track rules it says if it dosen't say you can then you cant. This covers them on people doing things they couldn't think of or so to keep the rules from taking up a good sized library. You could write books on what not to do just on the heads alone. I personally like to have rules that are black and white so you know where you stand on all issues.

Ok i went and bought a 6 volt battery at walmart tonight it was a 6 volt flahlight battery the big ones and hooked it up and got a whopping 19.4 volts started the car and run way better but that little battery got warm not hot but warm. What is that going to hurt if anything or is this even going to work at all? How long will that battery last with 12 volts pushing it?

Your 19 volt setup wont hurt anything. The electronics and electrics in your car will stand 24 volts. Beware, 24 volts is at the limit and some things will likely fail. Get a rechargable 6 volt instead of buying lantern batteries. This will get you a safe 18 volts. Dr. Chris Jacobs (Jacobs Electronics) told me about these voltages a number of years ago. I had been running 18 volt HEIs and wondered about voltage damage.
I ran an HEI at 18 volts in a sprint car. Used 3 small 5 amp 6 volt computer backup batteries. The whole ignition was lighter than a mag!

Ok today we bought a 6 volt motorcycle battery and hooked it in a series with the 12 volt and have a total of 19.4 volts.

Next question is what plug gap would you run now I am at .045
This is a hobby stock with 9to1 comp. and stock heads,intake,manifolds. 2bbl carb

I don't know but here is something to thing about if you have the 12v- 6 volt hook together it will not do anygood if you start the car with both batterys together i have read once you have the car cranked with the 12 volt then switch to add the 6 volt to the 12 volt after the engineing is run there must be two switches i think one for the 12 an one for the 6 you may need to check and don't forget to turn both switches off they claimed it drains the 12 volt after starting the engine then add a swich for the 6 volt to put it back.I have a article on it if i can find it .

OK here is how it is hooked up

We have a ford selinoid to begin with,
It is hooked like some one woulld normal hook up one except in line to the distributor from the dead side of the switch it is hooked to the neg side of the 6volt then a wire runs from the + side of the 6 volt straight to the HEI thus giving me 19 volts.
So when I shut the switch off it kills all power to the hei and kills the neg side of the 6 volt so no juice goes any where I used good 10 guage wire so it keeps good amperage NOTE::::: i found out that if you use 12 guage or less wiring to the HEI you lose a ton of amperage not volts but amperage (didnt know that) LOL
Also this keeps my lights at 12 volts and my Tach also at 12 volts
