Racerty1 Posted May 2, 2007 Report Share Posted May 2, 2007 Does any one know the best(the most volatile) mixture of gas to air? Like is it 50g/40a or what? Quote Link to comment Share on other sites More sharing options...
Jay-qu Posted May 2, 2007 Report Share Posted May 2, 2007 Well, that depends on what the gas you are mixing is! Quote Link to comment Share on other sites More sharing options...
Guest chendoh Posted May 2, 2007 Report Share Posted May 2, 2007 Off hand I would not know for sure, but several variables immediatly jump to mind. that would preclude your 'best' scenario.If, by your handle, you are into racing you should already be aware of them to. Altitude....Air temp....Humidity..Density of the raw fuel itself, The middle two help in finding a reading called Water Grains?That when one uses a special Hygrometer-Hydrometer set, a racer can set the best density for the location that they are racing. I have seen Dragster Teams do it for years, but when you ask them how they do it, they will shutdown faster than a blower explosion. Secrets you know....:hihi: Ahhh... The smell and burning sensations of Nitromethane :( Try a Wiki or goog search Quote Link to comment Share on other sites More sharing options...
Racerty1 Posted May 3, 2007 Author Report Share Posted May 3, 2007 Yes, i know there are several variables to determine this, i.e. air temp, air density, humidity, temperature, gas mixture density etc. Lets say its at like 500 feet above sea level, humidity is at 30%, its 75 degrees outside. Using standard Premium 93 octane fuel.Any ideas? Quote Link to comment Share on other sites More sharing options...
Guest chendoh Posted May 3, 2007 Report Share Posted May 3, 2007 Have you ever heard of: :) I can give a man a fish and he will eat for a dayBut, if I teach him to fish he will eat for the rest of his life? I will take you as far as this Gas Mixture - Google Search The rest is on you. Quote Link to comment Share on other sites More sharing options...
Jay-qu Posted May 3, 2007 Report Share Posted May 3, 2007 octane + oxygen = carbon dioxide + wateror2C8H18 + 25O2 = 16CO2 + 18H2O per 2 molecules of octane you need 25 molecules of oxygen Quote Link to comment Share on other sites More sharing options...
Jay-qu Posted May 4, 2007 Report Share Posted May 4, 2007 sorry had to go to uni.. got some more work to do on this yet :naughty: I just read Octane rating and noticed that the 93 is not a percentage of octane present but (for you US citizens) is the anti knock index. So there is no clear way to tell how much octane is in that fuel (and other additives) and so I cannot calculate an exact air/fuel ratio.
