People are IDIOTS! - E85

[hippiekiller]

Dig around on EvoM or Talk/Tuners, you will find a lot I am sure. You should just show your professors. If you have your old tune files, load up the old one and run premium. When you run out of that switch the file back and switch it to E85. May have problems demonstrating long term effects.

[4g63tcrazy]

Alright I got plenty of people saying they make more power with it but now how about long term use? With corrosion and stuff like that? I have been searching around and most have used it for years without any ill effects. How long have you guys been running it and have you run into any problems?

[dumb_ricer]

E85 isn't much more corrosive than E10 fuel, which all cars have to be capable of handling. And of course they try to overbuild anything that would cause fuel to leak (or so you'd hope), so it doesn't really corrode much at all.

[viridionplague]

i think the best thing you can argue is the fact that alot of people get ethanol mixed up with methanol

methanol being highly corrosive.

also there is around 10-15 % ethonal in normal gas, and there has been debates for a while about raising the ethanol content of regular gas to as high as 50%

Since 1977 the government made mandatory to blend 20% of ethanol (E20) with gasoline


as somone stated before the bigger injectors and fuel pump is to account for the added 30% usage


you also need some kind of tuner, for one to account for the 30% and also to account for the different burning caracteristics of e-85.

e-85 burns more efficiantly and cleaner.

another thing to note is lean / rich mixtures of either fuel. stoic (ideal) afr's for gas is 14.7 and for e-85 is around 9


as well if you look at octane ratings, the highest you can normaly get at a pump is 93, thus limiting boost or compression depending on application.

where e-85 is normaly around 105-110 helping prevent detonation at higher boost levels or higher compression levels

My neon runs fine on E85 without any modifications. I fill up with it about 25 percent of the time. It isn't even any slower than on regular gas.

My ECU is just that 1337!

[Shane@DBPerformance]

A Neon isn't a performance car, you could probably fill it up with moose piss and it would run the same.

Just have your classmates look here: http://www.dynomaxdynotourblog.com/

Most of them are on E-85

I'm raising the bullshit flag on that one. It is LESS efficient, and I doubt it is any cleaner. Maybe your car smells like popcorn, but still, it puts out emissions just the same as gasoline.

What does OPEC stand for?

E85, which is 85 percent ethanol, emits less smog-producing pollutants than gasoline, but provides fewer miles per gallon, costs more, and is hard to find outside the Midwest.

e-85 also burns faster, hotter and produces more enegry per charge that gasoline.

the only downside is that you need 30% more.


if you take 2 cars with the exact same setup only one runs e-85 tuned for it, and the other runs gasoline. the car running e-85 will produce more power but will use 30% more.


dollors per mile are about the same e85 being slighly lower, but the e85 makes more power at the same settings, but it allows for more boost or compression

so emissions are better, hence cleaner.
as fore efficiency it depends on what your arguing

[viridionplague]

just did some quick math, overall, and this depends on where you get your fuel specificaly.

e85 costs 11% more than gas to travel the same distance

but this depends on your tuning and on the price difference between e85 and gasoline.

there is an average of 20% difference acrost minnesota

E85 has a higher octane, allowing to add in more timing and boost before seeing knock. Therefor you can run leaner.

Just look at Englishracing.net That says enough

[SnoEclipse]

The only reason E85 is 'cheaper' is a $1.25/gallon tax subsidy.

The money still comes out of your pocket.

That may be true but you really need to watch your EGT's. You can just as easily melt stuff with E85 as you can with gas.

Whoops; wrong!

E85 is one of the biggest scams this country has ever fallen for. It does nothing good for the environment or economy. Also, please keep in mind that 1 gallon of gasoline/diesel is needed to make 1.3 gallons of ethanol (according to Time magazine as of this past summer; I linked to the article elsewhere on this board).

[Halon]

I don't use it for environmental reasons. I use it because it performs well, and doesn't kill O2 sensors like leaded did.

[1QUICK4]

And it's cheap.

[TalonFiero]

E85 does burn a bit cleaner than straight gasoline BUT it takes a lot of energy and outputs a lot of pollutants to create E85 and that's the part of the process that people point their fingers at.

Of course E85 is also govt subsidized so we are all paying fot it whether you buy E85 or not. Thank you Hughes! ;-)

Bottom line is I would still buy the stuff if it coast the same as 92 octane fuel.

Evo 30k miles 2yrs, Talon almost 4yrs.

I made 291hp on 92 octane, I made a best of 377hp on e85. It allowed me to raise the boost 6psi, add more timing, and i guess run a little leaner than pump gas.
