E85

[The Riot Hero]

rules. if you have it near you you should run it. just got my car running on it a couple days ago

[Nismoknightska-t]

i would too.. if there was a local e85 station

I would have to drive 20+ miles to fill up

[CKAMC]

have to run larger injectors as well....

[GabeS14]

what are the benifits of running E85 heard a lot about it recently, but no details...
? is it just cleaner?
do you loose or gain power? by what i heard you loose some power, but then, the guy drives a jetta so cant believe what he says.

Dahmer we have E85 gas 20+ miles away from us. I thought we still didnt have E85 in SOCAL. Good info thanks.

[brndck]

and it takes more e85 to make the same amount of power as gasoline. yes it burns cleaner, but the amount of energy it takes to produce it almost negates any benefits of how clean it burns. or so i've been reading. as far as i can tell from everything i've read its just a way for american corn farmers to get more govt subsidies. its cheaper and more effective for e85 to be made from sugar cane (which could be bought way cheaper from south american countries) but yet were still buying it from american farmers which jacks up the cost of all produce and imo ends up jacking us all. there was a rly informative article recently in rolling stone about it.

i guess its progress in the right direction cuz people are actually trying to make a cleaner burning fuel, but it seems like another scam to me.

[240trainee]

I'm building my car to be compatible with it, so if it becomes available near me I can try it out.

[steve shadows]

like twice larger

[CKAMC]

like twice larger

yup, might as well run a dual fuel pump system while your at it.

[The Riot Hero]

who gives a crap how clean it is and sugar cane andsouth america. it makes POWER. im running a single walbro with 850cc injectors alittle over 400whp 8:1 a/f id like to go alittle richer and i still have another 10 psi or so i can run through this turbo bu my injectors are at 97% duty cycle.

[guitaraholic]

I know this is bringing this forum up from the dead, but here's a cool factor to consider. E85 has an octane rating between 100-105, so if you have the ability to switch fuel maps, you could boost the heck out of the E85.

The reason I bring this up is, in Utah for instance, the highest octane you can get is 91. So if you get your car to work with E85 (change tank, seals, ect) you could hit high boost numbers/aggressive tuning w/o having to get racing fuel.

Also, another idea, you could get an adjust FPR and turn it up when you have the E85 in, I will research it more, that would save you having to "tune" for both. With the E85 in,, you just increase the pressure a bit which allows the injectors to flow more.

[Howard92884]

E85 has 2/3rds the energy potential as gasoline. So you would travel about 2/3rds as far on E85. But E85 has a very high octane rating so it would be good for high boost/high compression applications.

just turning up the FPR is a terrible idea. but if you have a PFC or AEM and have the ability to load maps yeah its fine. the tuning is completely different youll need 100% seperate maps. fuel and ignition...

my timing is pretty aggressive even for race gas, i run about 7.8:1 a/f at full throttle. the car makes around 410whp at 17 psi with a tial .64 a/r GT2871R (not the same as a garret 2871r)

you dont need to change seals or hoses E85 is non corrosive. i have about 4k miles on mine. my car is tuned poorly at part throttle, i have to change the oil every 1300 miles or so, it should be better when i get an O2 sensor on it and tuned properly. you have to run lambda wideband setup, i use PLX, not sure if AEM displays lambda but you can do the conversion but its a pain in the ass.

im out of fuel with 850CC injectors at 17 psi youll need to use top feeds if you plan on any big power. and probably upgrade to -8an size lines. im using a single walbro 255 high pressure on stock fuel pressure with stock regulator, ill be using a fuelab brushless pump and -8an lines and 70 psi fuel pressure in spring.

if you have access to E85 do it. its good stuff

[Antihero983]

one thing to keep in mind is that E85 will allow more moisture into your fuel system. so make sure if you live somewhere it snows and the car wont be driven for days at a time you leave it with at least a half a tank. thats the problem with alot of the gas companies these days, theyre changing the gasoline mix and adding E85 to it, which is allowing what i mentioned before to happen with regular good ol' gasoline.

[smelly240]

when combined with oxygen e85 has the potential to do bad things to rubber.... and like they all said, u'll need more fuel - other than that its a good fuel. if u dont have a station with it tho - u can try mater/meth injection.

a lot of people have switched over to it in the midwest.

[Antihero983]

also from what ive read, these new chevy "flexfuel" cars, have been getting worse gas mileage off of E85 then regular gas.

[u_contempt]

(this is all from things i've read.. i could be wrong... though i don't think i am) e85 from what i've read is like 102 octane. if you ran pure ethanol it would be 115 i believe. it burns cooler because it has less hydro-carbons per molecule thus the less power per molecule. but it does burn cooler which allows for higher compression or more boost. it does get less mpg but who cares when you're using it for a performance application. the great thing is that you're not taking carbon out of the ground and dumping it into the air like gas, since you're growing crops that use the c02 to make the alcohol. biggest drawbacks are if you don't have the infrastructure to get it or produce you're own (it's legal moonshine), it doesn't pipe well like gas and since it's a crop most of the time you're using fossil fuels to harvest, produce, and ship it. also, since technology is still fairly new with it it can take a lot of acreage to yield barrels. which makes it really hard to grow fuel and food for an entire country. like everyone said it requires more fuel so larger injectors, fuel pump, and maybe a fuel pressure regulator. i think with pure ethanol it requires 33% more fuel. also (at least around here) all of our gas stations already blend up to 10% ethanol into gas.

personally i will be running it the very first opportunity i have to. it isn't the best alternative but it is a step in the right direction to become less petroleum dependent. i mean who wants to pay 4+$ a gallon for 93 octane this coming summer...

[MegasquirtCA]

My standalone has the abilitiy to alter the maps when it senses E85 :D no need to load new maps.

have you tested it? i have it works like ass.

[KA-T_240]

I plan on swapping over to it next winter if the budget allows. I kind of would rather spend the $$$ on a paint job, but we will see what happens.

E85 is really big up here. We have probably 6-7 guys that have swapped to it that now don't need to run race gas. one is a 1382whp Cobra that is street driven.

all you need is big injectors and a tune dude. do it. shits retarded expnsive by you, its about 2.70 a gallon here. was 2.13 a gallon in ohio when i was down there, 2.50ish in knoxville TN

cruising gas mileage isnt affected much, but around town you will see a difference, i get about 230 to a tank average mix of freeway and around town and boosty. when you boost it goes away fast.

[nissan240sxkid]

what about the E100

What code you running?

E85 is around 2.15 here the last time I checked. Besides Injectors I know I am going to need other things(engine management), and I may be starting to get close to maxxing out my fuel pump. Not sure of the limits of the walbro with E85

I wish I got still 230 miles to the tank. I used to get 240 miles a tank when i was NA. Now i get around 170 on a tank, but I beat the shit out of my car.


What do you use for a wideband? I have a AEM Uego but those do not go down low enough for E85 A/F Ratios

im using PLX since it displays lambda. im using a single walbro at 400+whp will be going wth a external over the winter. walbro seams to be holding up fine.

[cdlong]

when it's stoich on E85 it'll tell you it's at 14.7 since it measure the amount of left over O2. the number is based on a calculation in the gauge. you either have to make it show lambda or do the math in your head.

also from what ive read, these new chevy "flexfuel" cars, have been getting worse gas mileage off of E85 then regular gas.

that's because of the lower energy content like Howard said. though i think it's closer to 3/4, whatever.

The uego has lambda option.


and E85 has differant A/F ratios that you need to tune for. Who cares about Idle A/F ratio(yes its important) I am WAY more concered about monitoring WOT 20+psi pulls A/F ratios.

[Blown240sx]

I love how everyone is bitching about how you have to use more fuel and its not as efficent in making power but what everyone neglects is we can mass produce this stuff from MUCH MUCH cheaper than Oil will ever be.
Also with Fuel competition gas prices will be forced down also. Look at Brazil after the oil crisis in the 80s they went to E85 a long time ago. US thinks this is new technology but its been around since the 80s if not earlier.
Brazil cut incoming fuel sources to 10% and produces a majority of it electrical energy from Ethanol burning factories.

[leveloneae86]

anybody into E85 because it will exempt your car from smog in cali? which then means you can swap whatever engine in your s13 or s14 like an sr or whatever?

The only reason E85 is as cheap as it is right now is because of the amount of Gov. Subsidies(sp) when they go bye bye, It will be close to the same price as regular gas.


In my opinion, a dramatic swap to E85 on everything isn't going to happen for a LONG time. If we would go to having all gas sold in the U.S. E10 or even up to E20, it would sell WAY more ethonal then have E85. At that level or ethanol in the gas it doesn't require most of the changes that running E85 does.

[PoorMans180SX]

They run more than 10% Ethanol in Chicago in their regular gas. I've heard it's becoming a problem, because it doesn't have the lubricating properties of petroleum. They recommend everything rubber be replaced with "Viton" synthetic rubber, and to make sure your injectors are compatible. I'm thinking about getting an ECU with switchable maps, so I can run E85 and gas.

Saab's BioPower engine makes 148hp on gas, and 184 on E85.

Um, we (Chicago area) have been running E10 for over a decade now. I have never had any problem with the fuel lines in any of my vehicles evar.

[KA-T_240]

All gas sold in MN is E10. SD has E10 for all 89 octance(and its cheaper then regular) and some other gasses as well in SD are E10. Not sure on ND but i think they dont run any enthonal at all, which is nuts cause of how many Ethanol plants they are building here.

I was told it was only in Chicago (like down-town) that they do this, running up to 20%. Maybe it was recently corrected.

Manufactures began using alcohol approved tanks and lines since the mid 90's.

1988 for most manufacturres. good info, nissan stuff seams to be holding up great.

[guitaraholic]

From what I have been reading, you need to replace all your fuel lines, seals, and even your tank, if you want to run E85.

I'm in Salt Lake City, and E85 is going for $2.89/gal, which isn't that much of a bargain (damn gas station is keeping the govt's price break,, I assume). Still might be an interesting thought when I want to crank up the boost (its 100 octane), would just need even bigger injectors (currently 550's).

Edit: Someone here mentioned about emissions, and being able to run an SR in Cali without worry, because its an "alternative" fuel vehicle. I did a little research, and found this not the case. That a car converted to E85 has to meet or exceed its current emissions standard compared to if it ran off of Dino Juice. If anyone has a different view or more info on the matter, it would be greatly appreciated.
