HEY! DC of
15!Bring on the nitromethane! 10% alcohol!
You can throw out all of the gas records. Maybe we should have "pre-2008" records.
The previous records were set with a maximum dielectric constant (DC) of 2.3. Gasoline is tested using cyclohexane, with true DC value of 2.025 as a test reference. SCTA allowed a maximum of 2.3. This reflects the conductivity of compounds containing only carbon and hydrogen. All gasoline compounds consist of only chains of carbon and hydrogen.
There are very few racing fuels that have a DC even close to 15. Adding oxygenates that will give a DC around 15 will add a bunch of horsepower.
Allowing a DC of 15 means you can run methanol. It also means you can run nitromethane. No? Give me a decent test for nitromethane in gasoline. The rules say no nitrogen bearing compounds, meaning nitromethane. Also ruled out are propylene oxide and ethylene oxide. Good luck testing for those.
testing for the dielectric constant (D.C.) value, color comparisons, specific gravity, gas chromatography, mass spectrometry, and/or other testing methods.
DC is the only realistic test they have. Color comparisons have to be done in a controlled lighting environment to be valid. Specific gravity testing isn't going to tell them anything based on the number of compounds you could possibly run.
SCTA doesn't have the budget to do testing for gas chromatography or mass spectrometry.
They have really let the cat out of the bag on this one. I have no idea why this sounded like a good idea to anyone. Event gas will no doubt be something other than plain gasoline.
Non-event gas, like El Mirage, is going to be like the old wild west.
