From everything I've read it's more like 104-105 (R+M)/2 octane. Those 107-110 numbers might be from UK types quoting RON numbers maybe?
Also, like Dre said, it burns cooler, and on top of that it takes more energy to evaporate than gasoline. This means as it turns from a liquid to a gas it cools the intake charge more than gasoline does.

i dont see why not, its just a matter off getting the fuel system up to far and some good tuning

The High performance value is the octane of E85 is about 107-110. It also burns much cooler which is great for high boost turbo applications less chance to detonate.

Only one draw back is consumption is higher

I was more just making a parallel that you can get similar performance results if not better with e85....I know its not race gas, but what you can do with this gas is amazing.....

Maybe its around 104-105 octane.....maybe.....but it has the capabilities that c16 does which is 116 octane as far as what we can do with tuning..... e98 has the capabilities of VP import....which is 122 octane, and yes some amazing cooling effects though.

That's very good to know. Thanks.

It will def. benefit. I've seen a chart that showed with E85(104ish octane), the limit of compression was around 18:1 with good tuning. You could build a 14:1 + comp. N/A motor, easy, and you wouldn't have to pay for expensive race gas. E85 would def. be cheaper and easier to find than race gas. We have a quite of few gas stations that have E85 in and around Madison area.


On a side note, here locally, we had a company that made E85 and they were selling it for around $1.25/gal. He stated that he made a very good profit at this price and didn't see a need to sell it for more. Once the oil companies found out, they put a stop to it. Now you see it competitively priced. F'ing oil companies!!

Here is a website that shows E85 gas stations across America"

^^Word. Fcking Oil Companies.

E-85 will never be viable as long as we continue to use corn for our source of ethanol.

So in reality fck the US for paying out the ass in subsidies for farmers to use corn to make E-85

^^Agreed. Brazilian ethanol is much cheaper to produce. Even shipped over its a better deal. Lets see if this talk of cellulose ethanol bares any fruit.

I'm sure the US can find a source as efficient or more efficient than Sugar Cane. I'm thinking of all the grass clippings that are thrown away and all the leaves that fall to the ground every autumn.

Hey everyone I'm bringing this back up because of some recent reading of the E-85 wiki.

There is mention of arc prevention.
"For vehicles with fuel-tank mounted fuel pumps, additional differences to prevent arcing, as well as flame arrestors positioned in the tank's fill pipe, are also sometimes used".

I haven't read any comments on this thread about possible arcing with the intank fuel pump. I've looked at the B13 fuel pumps and the wires are exposed. From what I understand regular gasoline is a dielectric so it isn't a problem. However alcohol fuels conduct electricity.

Any thoughts on this from the guys running E85?

I've never heard of anyone having a problem. There are thousands of people using E-85 in 90's fuel tanks with exposed fuel pump wiring. I'm not saying it isn't a potential issue, but we've never had nor heard of any issues.
