I had a try in completing the calculation, hopefully without to many hickups. If you see one please let me know.

I took over the assumptions of Timeshell:

Assuming

Speed 60 km/h (constant)

Economy 10 L/100 km petrol

6 cylinder engine

We can arrive at 0.1 L / 1 min petrol consumption

If we divide the consumption of 0,1L/min of petrol by 6 cilinders we have 0,0166666 L/min Petrol for each cilinder

If we start from the principle that the Hydrogen in the Petrol is the real energy source of the fuel we need to calculate the amount of hydrogen in Petrol. Based on the wikisource (compositon of petrol)

http://en.wikipedia.org/wiki/Petroleum, i found out that petrol contains between 10% to 14% of hydrogen. I will take the average 12% of hydrogen in pertrol.

This means 0,0166666 L/min Petrol for each cilinder x 12% of hydrogen => 0,002 liter/min hydrogen

Now lets calculate the amount of water we need to create the same amount of hydrogen. In the document "International Independent Test Evaluation Report" (see previous attachment) I found out that H20 has 20% of hydrogen in it.

So 0,002 Liter/min hydrogen divided by 20% gives you the amount of H2O needed : 0,01 Liter of H2O/min

Now that we have the H2O amount we can calculate the amount of HHO gas we need to procude:

I found on this site

http://www.newton.dep.anl.gov/askasci/chem07/chem07088.htm that you get 1334 Liter of HHO gas from 1 Liter of H2O.

So this means 0,01Liter of H2O/min x 1334 => 13,34 Liter of HHO/min (this is an approximate number!)

So for each cilinder you would need +/-13,34 Liter of HHO/min to have the same hydrogen energy values as Petrol.

In the document "International Independent Test Evaluation Report" Stan Meyer calculates how much HHO production he gets in ideal circumstances from one tube out of his tubular cell. That is 0,77L/min of HHO.

If we take this into concideration we would need 17 tubes in a tubular cell to produce the needed amount of HHO to drive one cilinder of our 6 cilinder engine. This tubular cell (17 tubes) would consume 952 watts of power to produce the gas.

All this makes me conclude that it's not enough to just produce great amounts of HHO and inject it into the engine to replace petrol. We should find an efficiĆ«nt way to use HHO/H2O as a fuel. For example we need to manipulate the HHO in such a way that you get a high energized fuel. So My proposal is to start experimenting with the energyzing of the HHO we already got and improve it's energy level. Just like Stan did. I think Hydrocars has a point in his post "Water is Fuel" :
