If I could get it regularly, I'd seriously consider switching.

So, I have read all the posts in the linked threads, as well as the threads they linked to. Seems like the same story in every thread. People claim it eats the fuel lines/pump but no one can definitively prove it does or not. There are 1 or 2 who run it, the one guy who did replaced his pump out of fear something would happen...
In UT, like CA we have 91 poo-poo gas. There's a station right by my wife's salon that sells E85. I'm really thinking of adding in a bit of E85 to up the octane a bit. hmmm...

I'm coming out with an e85 conversion kit after I clear my plate. The new intake manifolds already have it built in, the only thing you have to add passed whats on the intake manifold is a fuel pump. You can guess the stock fuel pump is not going to keep up with the demands of even a modest turbo charged setup.

I have been using E85 for nearly a year now...
My experience has been nothing but great; but you do need to work with it a little.
99% of the time I run 50/50 mix of E85 and 93 gasoline with a small drop in MPG but great increase in HP. There is much less if not absolutely no pinging when running stock timing @ 11 PSI boost. I've had to run 305cc injectors with my FMU maxed out to compensate for the added volume of fuel needed for a good burn.
On hot days I will run 60/40 E85 to 93 and the car feels as if it were running in cool weather; so it is killer for summertime ping protection.
In all honesty there is no benefit on $$$ that has been seen since I do need like 30% more fuel with E85 blend vs. normal 93... so for saving money it's a draw.
Purely from a performance standpoint... E85 is great but it does take larger than stock injectors and blending of regular gasoline to make it work. In my case since I have no timing reduction in place, like a real ECU like MS or the like, it was a cheap way to get more boost for my ride. If I am stuck with just 93; then I have to cut the boost below 8PSI to keep the ping away.
Finally, as far as fuel system problems... since I am still using regular gasoline there has been absolutely no issues with the rubber lines. I can't say for sure that it will stay this way; but detonation will kill my motor before anything else... so it is a bandaid till I can install a "professional" solution such as MS and 550cc injectors.
Hope this helps and cheers,
Prospero

I would watch out on the hosing on any car. I don't know what the composition of the rubber is, but you should probably replace it with a nylon stainless braided or some type of polytetrafloraethlene (PTFE) polymer like FEP. This is a small cost for quieting your minds worry about whether you fuel hose is going to pop in half or not.
E85 is roughly equivalent to 105 octane for those wondering.

You can run it all on it's own too. You don't need to blend it if you have a stand alone. I think the blending is if you don't have a good computer/ECU to upgrade. The SR/RB guys running it here use a friend of mine to tune their ECU's. So if you run it straight you need a tune. If you blend it, you can probably do some small adjustments.
E85 is definitely good for the track/hotter areas/making huge HP. It lowers the knock considerably. There are guys that swear by it. Once I get my standalone (thanks Travis) working and my car moving properly, I am switching over to E85 but also going to be using 91. Just depends on time of year and what I am doing. Some places carry allot of E85 and some don't. Point being, Omaha has allot of E85 places.
