In summary, we had an 800 rpm gain along with an extra 195 seconds of running time.
Using these basic test figures, and applying them to the various tire, wheel sizes and gear ratios used today, I conservatively estimate that this would give an improvement in MPG of between 25 to 30 percent.
We still have various other sizes of the HydroGenX units to test on both petrol and diesel engines, ranging in size from 30 Ci to 1150 Ci.
