Dude like the ideas!

I'm new to hho, I'm working on a 73 super beatle for drag racing,
I'm trying to promote a green drag racing string
Here is my idea
A Pressurized system
I will use dc current to the drycell
And hho into injecters to motor

Now obviously water heats up with a current going through now is it the amps that heat up the water or is it the volts? Now yea obviously its a factor of both but which is more I guess is my question.
I think its amps cause amps can kill you volts knock u out
So let's say u put 6.5 million volts and 2.8 amps into a pressurized drycell and just making this up, but that 6.5 made a pressure of 800 lbs every 3 seconds used as a booster/nos into a system of 12 volts/5 lbs at engine idle, a 720 volt/ 30 amps for a accelerator at a 5 to 400 psi range of acceleration
Now that would mean it would have to be a pressurized strait flow system or would it need a pressure tank but if I did that I could have a option for even higher psi.
But now we come to operating the tanks output at a a lower out put with a high pressure behind it such completely loses me because that throws everything else out or does it because then in turn I would need 2 accelerators one for acceleration and one for booster speed but would that mean another tank? I don't know. I ramble on and intern get lost basically could my system work and if so how big would I need my drycell or would it matter considering the voltage?

Thanks for reading My nonsense
