E85

E85 contains 15% ethanol which is alcohol. Alcohol contains oxygen, and has less energy content than gasoline on a per lb basis, which means you need more fuel to generate the same amount of power. You would have to rejet as stated earlier. Stay away from alcohol blended fuels, you best bet is just to run gas.
 
ive seen this discussed on other forums and theres tons of guys that run it but say that you have to up your jets by about 25% and change your fuel lines becouse thats what it eats up first but they say that they use it mostly if u are on that border line of pump gas or race gas and its convenient and local also its way cheaper than race gas alot of people on quadracerhq run it so they say

E85 is 85% ethanol .which is alchol made from cron in the USA
 
My bad. I got is bass ackwards, E85 is 85% ethanol, not 15%. And the feedstocks can be corn, as well as others.
 
dont run that fuel ,you will just lose power even if you rejet accordingly,
us race guys run methanol ..not ethanol ,theres a difference and the e85 will get les power per drop as mentioned and often contains and absorbs water ,not everything you read is true ..e85 is no race gas by any stretch of the imagination.if yo u want a cheaper alternative torace gas run 100LL aviation fuel instead if it fits your application
 
I am no race guy so I ran E85 in a four stroke with good results, but it was in a race motor? lol

I am also not a fuel expert & E85 might not be for your setup, but I do know you should match the fuel to the motor. Even certain race gases will do more harm than good in a stock motor.

So I would like to try & state the truth, all facts? Correct em if I am wrong cause thats possible? lol

Not all alcohol is the same different forms react different & have differnt properties. Methyl Ethyl Butyl I believe are the 3 main forms.

Alcohols, when used near their stoichiometric air-fuel ratios, produce more power, a larger quantity of fuel is required to produce a specified power output. For example, in an automobile, more fuel is required for each mile driven.

Oxygenated fuels (alcohol) considered race or not will need bigger jets, since the fuel contains oxygen. needing more fuel to offset fuel containing O2.

Most forms burn cleaner, less carbon

alcohol burns slower so advanced ignition is important for a complete burn? In the motor it will have a longer burn, which will usually produce a stronger midrange

Higher compression also helps take advantage of the fuel properties?

Generally, methyl alcohol is the most corrosive and butyl alcohol is least corrosive. Methanol is corrosive & you should flush your fuel system correct?

Alcohol will absorb water hence why it is used as an gas line antifreeze. This is good in most cases & in stock motors. May be a issue if you allow it to come into contact with moisture, but moisture not good for any fuel?

Aviation fuel octane is rated different so it would have a lower rating if tested the same as pump gas.

Also anyone running a alcohol in a 2 stroke/premix during cold weather should run a Castor oil as to avoid oil gas separation?
