Is e85 a safe fuel? My set up is a 1995 Acura Integra.

Engine: B18c1
Turbo: t3/t4
Pistons: Mahle 9:1
Head: Stock
Connecting Rods: Eagle I-Beam
Intake: Victor X
Exhaust: 3 inch Thermal
Computer: Chrome tuning
Spark Plugs: NGK BKR7E
Fuel Injectors: RC 750cc
Fuel Pump: Walboro 255hp

Will the fuel mileage be much worse then if tunned on 93 octane?

How much more power can I make with e85 then 93 octane?

Is E85 corrosive to the tank, lines, engine?

you will have to retune for e85. I would guess that there is enough flow in your current set up to not need any upgrading for it. I'm planing on running a moates 2-timer in my ecu so that i can switch back and forth between e85 and 93 if they ever get a station that has it in new england.

p.s. you'll probably be able to get a little more power out of e85 as well

 

For those planning to run this fuel, how (if at all) do you intend to modify the fuel system to ensure compatibility with E85?

 

There is really to little modification necesary to the fuel system. E85 need about 27% more fuel due to it's slightly lower energy content. Pretty much every fuel injected vehicle on the road has ethanol safe fuel systems because they have been mixing it in to pump gas (in much smaller quantities) for AT LEAST the last 11 years (I'm ADD and i get bored and read the stickers at the gas station since i got my liscense). Other than that all you really need is tuning for the different fuel requirments and timing to take advantage of a roughly 100 octane fuel. The only other caution is that unless you have something to switch the ecu program between E85 and regular old pump gas you will have problems.

If you are looking for more information you should be able to find it on the internet. SAE has tons of good info but I'm not sure how much is available to the public.

It's true that almost all relatively modern vehicles are safe for use with ethanol-blended gasoline, but as you stated, this is limited to low-concentration blends (normally 10% is quoted as the upper limit). E85 obviously contains a much greater percentage of ethanol, and is therefore not always compatible with components that would otherwise be fine with the lower-concentration blends found at gasoline pumps.

 

Anything rubber will be eaten away by the e85 "slowly" so you have to do the whole fuel system lines and everything. It is also hard on your pistons and rings if you dont have forged pistons and stronger rings. again its over time that everything has problems its not like you put it in and boom its broken. E85 is great for turbo apps. and the whole 27% more fuel is very true i have heard it could be as high as 33% on so setups. E85 is also oil hungry and you may run in to some problems with that in the long run. I am going to work on doing a full right up on this and get some better numbers and some pic. I have a d16z6 that my friend is going to throw in his car, i will check and make sure the piston and everything look well on it before i start messing with it.
