Switched to E85 today
Well I made the switch. I simply added 30% of fuel to the entire map and the car started right up and idled perfectly. Took her around the block, driveability was excellent. I'm running a TEC3. Very simple process. I will be on the dyno shortly and will post some numbers.

Update...
I also dynoed the car last night, I made 480HP on 20psi. I was cut for time so I could not make any changes to the timing, I just wanted to make sure the air fuels were ok.
On the way home for the first time in over a year I floored 3rd and it spun as if I were in 2nd. I then slowly hit 4th and it spun when the turbo came online. I have Pirelli 295's in the rear on an 11inch wheel but it was cold outside.
The E85 station was closed to I had to put regular pump gas when I ran out. I did not change the map back to pump gas and it started up and ran. It ran very rich but if I did not have the laptop, I would easily be able to get home!!!

made the switch also on sunday, dynoed at 21psi afr 10.0 made 561 hp was just testing i wanted to go to 30 psi, had some boost problem so that's why i didn't make it any leaner. felt really good at the price of $1.84 per gallon can't beat that.

It tends to fare better when stored because it doesn't gum up things over time. However, there is still 15% gasoline if running straight E85...and more if splash blending...but I have heard the ethanol will keep that clean in blends of 30% of more.

Just an update.
I pulled both fuel filters last week. I found nothing at all. I didn't even replace them, I reused them again. I was expecting to find all sorts of things in there after reading a few other posts on how good the ethanol cleans but all was normal.

The filters have been in the car from the beginning of the racing season 08, so about a year. I loaded a pic below of the filter and element. As for miles since running e85, about 150 miles a weekend and 100 miles during the week so figure roughly 3000 miles in 3 months.
Usually when my filters start to clog, the fuel pumps will start singing! They were not but I opened them up to see what E85 did to them.

Paper filters and alcohol are a big no no.
Fellow corn lovers, when using water absorbing fuels such as Methanol or Ethanol it is wise not to use paper element filters. These filters will trap water and become very restrictive. Do use stainless steel mesh element filters.

What kind of fuel mileage do you get with E85? I plan on running a mild ported NA engine in an FC. Obviously you don't really look at mileage when you want to make power, but I was just curious how much it is affected by the switch. IIRC you have to be able to flow 23% more fuel or at least that is what a lot of the flex fuel vehicles are setup to do. How bout Meth injection? isn't that kind of pointless then when you run E85?

It burns quicker than gas. I really don't have exact numbers but I can take some when I get a chance. I honestly cannot keep my foot off the gas with E85. I did have meth injection but was always weary something would go wrong on pump but with E85, you can just hammer the car all the time and not worry.

Here is my experience with material choice.
I am using E85 with a mix of stock lines, stainless lines, bare and anodized aluminum, I have had the E-85 in the car for a year now and have seen no detrimental effects anywhere. Although, I am running 1.25oz/gal of BeNol for the premix. So that may have some bearing, but I don't know how much.

I've actually done some more research on it and it seems the mixes they are using now which cost more to make are much less harmful and in terms of E85 should be able to be used with standard fuel system components.. So basically make sure your getting enough fuel in the combustion chamber and your good to go. Much safer than using alky injection to make big numbers. E85 FTW!
