I am nearly finished with my build z6 and turbo setup, and I have been seriously thinking of running e-85. I have talked to a few and read up alot and the only thing holding me back is supposedly the octane rating in it can fluctuate. I know it requires about 30% more fuel to be injected and alcohol burns twice as fast as just gasoline, but with the cooling effects and the 105 octane rating the more I think about it the more I like it.

Post up if you use it or have used it, do you like it? do you know about how much the octane really fluxuates? is it a big deal? I'm building this for between 300-325 but would also like to see 400+ when I take it to the strip.

WTF is this e85 ---- everyones been talking about? We aint got that in JDM land...is it something I should look forward to in a couple of years when I come home?

I would go with e85 as long as theres lots of gas stations that have it around you. In Florida theres like 3 stations near Daytona that have it and there all about 30 mins away.
i heard it deteriorates fuels lines tho.

there is a MAJOR issue with E85......

It's not always E85

In Ohio E85 can be between 85/15 and 70/30 at the pump. You'll have to take a fuel sample at every fill-up, hope you know how to use the bobber

Your gonna need 50-70% more fuel. To be safe double the size of your injectors.

I plan on going with 42lb SVO injectors for my NA D15 @ 13.7:1 compression, likely will get the fuel for free just for running a sticker. Yes I might have a sponser already! Krogers manager said a $25 gift card for fuel would be easy.

Really, how much E85 you think I'm gonna burn in a season?

About the rubber lines......I won't have that problem with a 2 gallon fuel cell mounted up front

Yes, I know about the lines, I am installing a fuel cell in the trunk and running new lines. another question I had is will a walbro or xenocron 255lph pump support 400 hp with E85? I'm thinking its really pushing it. when you run a fuel cell do you put the pump in the cell or in line?

What is this bobbler you speak of? where can I get one?

from what i have heard on e85 is a pretty high octane, comparable almost to 110. its 85% ethanol which is made from corn. this video i found a while ago was pretty sweet. guy made 500+ horsepower on it.

Yeah the octaine is somewhere around 105 from what i've found, but is not always the same, thats what i'm worried about.

DeleriouS

well if it were 70 30 what would the octane be around - 95-97? you're probably better off just getting a tune on 93, unless you live in the corn fields

ifly87

I pretty much do live in teh corn fields, northeast wisconsin, lol. I am the tuner so its not a problem to retune it for me. but I just dont want to have to do it for every tank of gas.
