Ok, I'll bite again...

30% HHO in what units (by volume? by weight?). I have a hard time imagining any on-board water splitter doing it fast enough to supply 30% of the car's fuel needs by either measure. What is the rate at which your system splits water on-board?

Quote:
Urban Conditions 10,3 Lt/100 Km CO2 = 243,8 g/Km

Extraurban Conditions 6,0 Lt/100 Km CO2 = 141,9 g/Km

Combined 7,6 Lt/100 Km CO2 = 179,5 g/Km

CO = 0,013 g/Km

HC = 0,007 g/Km
So these are the numbers for testing your modified Z, and are inclusive of changes to e.g. the weight of the vehicle? Does it include the weight of any on-board water storage? (and how long does that water last in kms or hours? Or are you picking up water vapor along the way to replenish? If so what are the limits on that at various relative humidities?) Do you have comparable numbers from the same test conditions for a stock 370Z?

I know you've mentioned dry-cell batteries in the past, which I assume are recharged by the alternator and use to provide current for splitting water. Is the test long enough that the existing charge in your battery array was not a factor (i.e. that you could pre-charge them to make everything work better and then drain them down during the test, or was it a complete cycle with the batteries maintaining the same average charge)?

There are a lot of questions you don't really answer. That's only scratching the surface. But the bottom line is that physics says you can't win this game on fuel efficiency, generally speaking. Maybe by combining the offset of several existing inefficiencies in the ICE design, you could pick up 5% or something, but then that would probably be offset by the additional vehicle weight and/or mfg cost and/or maintenance needs, etc. You've got an uphill battle against a brutal enemy, and his name is Science.
