I know it was stated that the use of e85 here isn't for money savings, but I just had to post this:

I checked, and in Western PA there are only 5 e85 pumps available to the public. I could only find out the price on one of them, and it was $2.99/gal. Premium (93 octane) at the same station was $3.59/gal.

The e85 folks say that e85 only produces 75% of the power/gallon that 93 octane produces.

Doing the math:
My SRT-6 gets 19mpg on 93 octane fuel. So if I spend $50 on 93 octane fuel, I would get 265 miles out of it.

Using e85 (at 75% of the mpg) that same $50 would only get me 238 miles.
To go the same 265 miles that you'd get on the 93 octane (for $50) it would cost you $55.60 in e85 fuel.

So this "green" fuel source doesn't sound so great to me. In the end, you spend money converting your car, increase the potential for problems, make it more inconvenient to fill up, AND the fuel costs more (per mile driven, not gallon purchased).

Where's the benefit Al? (Al Gore that is)

OK, I'm done ranting. Back to e85 performance talk...
