From the IHRA rulebook:

B: New dielectric constant (D.C.) of the gasoline must not exceed +1 for the following
classes: Top Dragster, Top Sportsman, and Super Stock.
The dielectric constant (D.C.) of

gasoline for Stock will remain at +2.3.


Just curious...anyone know what the dielectric constant of 91 octane unleaded is ?

I don't, but I think it's time to make some calls, because if I can run something other than regular racing fuel, it'll save my modest racing budget a nice sum of money!!! Given that other organizations are starting to allow unleaded fuels to help clean up the environment, it would also benefit us that way too....I'm interested!
