    Pure ethanol produces 34% less energy than gasoline, but it can also be fed into higher compression engines, therefore producing more energy. Anyone done any research on this>?

    What they said is true. I was a gas semi tanker driver for a Shell distributor for about three years, learned alot. E85 in a stock motor = less mpg & less power. Unless it is rebuilt (higher compression) or re-tuned way more volume than a regular Flex-fuel ecm will do stock.
