Has anyone come up with a design for an HBO generator to run an engine just on hho? How many lpm would I need to produce to run a 6.4 litre v8

Take a 6 odd litre V8 producing say 300kWb on gasoline. Apply a derate for straight hydrogen (say 75%) for knock margin, and you're looking for 75kWb. Apply a conservative efficiency (say 20%), and you're looking for something like 375kWth of fuel energy. The LHV of hydrogen is 121MJ/kg.

I'm sure you can do the maths from here...
