Re: ethanol vs. non-ethanol gasoline
No doubt alcohol fuel has it's place. Just not as a 10% additive to already-crappy pump gas. John Force isn't running E10. The other component that makes alcohol racing fuel so wonderful is that "nitro" prefix in front of the methane, and then the nice little methanol as a finish.
John B is right on. Today's "race gas" for bracket cars was known as regular when I was a kid. I have to admit, it is quite amazing the amount of power engineers have managed to squeeze out of the near-water we buy today at the pump. But for folks like me running 2-strokes that honestly qualify as antiques, modern pump gas was never part of the original design spec.
And I am not a fan of turning our food supply into fuel. But that's off-topic and I'll drop it.
