Hi

I would like to know, if you guys can help me?
I have hho on my scooter already but makes no difference on MPG , i'm not sure what's the problem, the production is low.
I now more or less 100ml per minute on wet cell , but i only have 12v 4a to use . What can i produce with 12v and 4a ? i can make my own dry cell i just need a plan.
I work with stainless steel (metal fabricator) but i'm not sure that a dry cell will work with 4A.
My scooter is 100cc 4 strokes .

I hope that you guys can help me .

Thank's
