Oh yeah, you can get good result with as little as 1 lpm, which means you can run a small cell and not use that much amps to get that. also, if you are traveling long distance, you mght want to re-think your configuration to +NNNNNN-, with 6 bipolar you use less amps and the cell will not get hot even without a PWM.
don't go too crazy trying to produce a lot of HHO for that 3 liter engine you don't need it.
