Hello everyone im new to the form and i had a few questions for some of the experts on the form.

So hears my plan i have a ski-doo its a 1973 elan with a 16 Hp 250cc twin engine and i plan to have a HHO cell that runs on a battery that i recharge with a battery tender at home so my questions are...

1: How many plates do you think i will need and about how big?
2: What container should i use to hold the cell?
3: How many flash back arrestors/one way valves should i have?
4: How can i control the flow of gas ie: how to make the skidoo go faster or slower (throttle)?
5: should i use +-+-+- so on or +n-n+ or is there a better way?
6: Is this possible?
7: should i use a dry or wet cell?
8: How big of a battery should i use?
I know some info on HHO gas but i need some help this is just an idea for now so its still in the planing stages any help would be great thanks.
