OK Been re-researching some thero on gas vapor:
How much does 1 gallon of gasoline displace as a vapor? The saturated vapor volume of an average gallon of liquid gasoline when fully evaporated is 160 gallons of vapor at 60° F and sea level.
It is hard to get more real data on the use of gas vapor.
I searched for the answer to this question and only found this site with a suggestion of a working ratio:
FuelVapor Technologies - fuel efficient vehicle automobile high mileage
And here they are again:
Fuel Vapor Technology – 3 Wheels – 180hp – 92mpg
OK So lets say I could get a 100% improvement on my stock cars: my Mercury could then get around 60 MPG and my van could get 32 MPG.
I think those numbers can be reached.
OF the some 15 cars I was involved in adding HHO we got two wild cards...Two cars that seemed to get around 60to 75 MPG.
Both we were unable to retest with a longer drive due to the owners leaving.
One car (a Hundia) got idle motor problems, and the second (a Toyota) was driven back east.
The first car once the idle motor was replaced, then was driven home by its owner whom began reajusting his car on the road and totally messed things up so by the time he got home he had it only getting 23MPG, a lost of 10MPG from his stock MPG.
The second owner called the next day COMPLAINING he was NOT getting the MPG he expected, that he was ONLY getting 56MPG....He called from two cities on his trip home with the same complaint...
Both cars were tested stock and both gave 32 MPG for a road test of 100 Miles driven at 65MPH with three men aboard.
Sadly these two cars were flukes and we could not get these results again.
BUT they did happen.
