I had taken some shortcuts, and had wired in a toggle switch to turn the generator on and off. I forgot, and left the generator "on", then went to start the car about an hour later. The explosion was deafening! It shattered my aluminum airflow sensor, and the plastic airbox.

I won't be attempting the HHO stuff again, unless I see MUCH more convincing proof in the future. (And if I ever do try it again, I will not be taking any shortcuts!)

Stoichiometric hydrogen and oxygen has extremely high burn rates. And using it in an engine via simple water electrolysis is largely hit or miss as you have found out.
