I had to do it...
I filled up with 'just one more' tank of race gas yesterday. This K04/APR fuel pump/104 Octane program is just so addictive...
I love this car!

APR should make an E85 program..
A few of the the B3/B4 guys are running E85 in their high-boost standalone cars. One guy mentioned that he can get more spark advance on his 110 octane program running E85 then he does on real 110 octane...
given that E85 is cheaper than 91 octane..... you might want to look into it

Lower energy density = more fuel
E85 has less energy density than gasoline (~20% less), so the engine would need more fuel to get the same power output with E85. Fuel delivery on the 2.0T is a hard enough problem with gasoline. Even the APR fuel pump might not be able to flow enough E85 to make it worthwhile.

That's a horrible idea...
E85 makes roughly 30% less power, and 30% less fuel mileage. Unless E85 costs 30% less than regular fuel- it's a TOTAL waist of time.
Further, using E85 will require modifications to your fueling system, and frankly I don't know if FSI (in its current form) would support it.
E85 also tends to absorb water vapor and contaminates, meaning the older the fuel- the lower its octane. This also means they cannot use the traditional infrastructure to distribute E85 to the stations because the pipelines contain lots of water vapor and other contaminates. These costs will be burdened on to us (the taxpayers) and paid out in the form of subsidies.
...not to mention that people in Africa are starving since the farmers sell the crops off to be made to ethanol. Again, this is because of the subsidies- it pays more to make it into fuel than to feed the hungry.
You won't hear that from Al Gore.
That said- there is much promise in further development of E85. IMHO, when they can make E85 more efficiently from faster growing crops, with lower soil leaching characteristics then E85 will be ready for prime-time.

Sigh...
I didn't ask for your socio-political analysis of E85.
E85 _is_ 104 octane chemically, but because it burns cooler than race gas, you can run more boost and more advance on it, especially on turbo engines.
It _destroys_ race gas in terms of price per gallon. So instead of paying $5 or $9 or wahtever for 104 race gas, why not pick up some E85 at 2.75/gal or whatever it is ?
I live in North Dakota. I'm fully aware of all the issues surrounding E85. I won't discuss any of them because that's not what is interesting to this forum.
What _is_ interesting is a way to get gas that's better than 104 octane race fuel at normal pump prices.
The one useful thing in your post is that it's not clear that E85 works well with FSI systems. But of course, if nobody tries it, we'll never know, right?

I agree with your assement of the *potential of the fuel.
My personal "socio-political" views prevent my full support of "mass" deployment of E85 at this time.
Though, in limited applications, I fully support it. I thought you were approaching this from the "Global Warming" perspective- in which case you have the wrong car. ;-)
Sorry for the lecture... not my intent, but it did come out that way.
