Ron and Eric,
Since E-85 has only about 70% of the energy (per gallon) as regular
gasoline, it's hard to believe that "little modification to the stock set-up is
sufficient" and "good fuel mileage" results. Also E-85 vehicles require
considerable mods as far as materials are concerned. That high a % of ethanol
will attack the coating on the stock LM Corvair fuel tank, for example. Flex
fuel vehicles (from GM and others) now on the roads have lots of changes from
gasoline only vehicles. One, of course, is a sensor that analyzes the fuel
flowing to the engine and adjusts the A/F ratio depending on whether straight
gasoline or E-85 is flowing or ANYTHING between those two extremes. This is
necessary since it takes a LARGER flow of E-85 to make the same power as
gasoline. So it's hard to understand how switching to E-85 will NOT produce WORSE
fuel mileage than regular gasoline. Of course, you could significantly
raise the compression ratio to take advantage of the much higher octane rating of
the E-85. Or, you could allow your turbo to make higher boost pressure with
the higher octane E-85.
But I don't see that these changes are "minor" ones from stock.

Let's see an article on what he did. Do the stock hoses in the fuel system
hold up OK?
