    And alcohol works better than water for evaporative charge cooling. Alcohol also has a significantly higher effective octane number than gasoline. So, it's really more than just an antifreeze.

    Do I see some proponents for ethanol in gasoline here?

    ethanol raises octane (or at least has the same effect) but the gasoline is likely at a lower pre-ethanol octane so that the finished product is the same. On the other hand, ethanol slightly leans the mixture which can have an adverse effect on detonation if not accounted for.

    There are lots of folks in the forced induction auto world who run water, water/methanol, straight alky, or even e85 injection on top of their normal efi for charge cooling. Shooting e85, not as a primary fuel, but as a charge cooler, works exceptionally well from what I've seen.

    Ethanol as rammed down our throats in every gas pump? Not a fan of that.

    I figured there was a rub. Still impressed with the speedway bikes that ran straight methanol (?) on ice in an enclosed arena. Slowly, heat after heat, the fog of combustion filled the whole place with an aura of bluish gray haze. It is a wonder we didn't all die on the road home, but what a fond olfactory recollection.
