8A@12V is 96W, or about .13HP.

Converting the mechanical energy of the engine into electrical energy at the alternator is lossy.

Converting the electrical energy into chemical energy (by splitting water) is very lossy.

Reburning the hydrogen and converting it to mechanical energy is lossy again.

Three losses-- where are your gains?

Also, that additional 8A load on the alternator is extra load on the wires in the charging system, which means the wires get less effective at carrying the electricity due to the heat, so there's more inefficiency.

Water injection in and of itself is a time tested way of increasing the efficiency of the engine, in part by allowing you to advance the timing much further than before (assuming the engine management allows you to do that).

If you can disable the electrolysis portion of the aquatune but keep the water injection functions, you might have a winner there.
