Yeah, I've always gone with the 2:1 figure. I'm sure it's not exact, but I'd say it's a safe guess given that on a carbureted car, you'll typically only need to increase your jet sizes about 50-75% (...usually)when converting to alcohol from gasoline.

Wash-down is a problem if you don't use a secondary lube in the fuel, like the "top-lube" we sell.

I don't know about straight alcohol, but E85 (85% ethanol) only costs you about 10% on the gas mileage. It's also 100 octane, so you car run more compression or timing. I remember that Ford built a test car that could run on both E85 and standard gas and they got 10% more power out of the car on E85 and it ran cooler.
