Well guys I was wondering if there has ever been an evo X running on E-85 I have looked on the internet but have not been able to find one done up. would be awesome to be one of the first but doubt it has not been done before.

 

Yeah, it's been done, (not by me) but seeing good gains from it. I thinking about doing it myself in the spring.

 

Can the fuel system take e85? I thought it was highly corrosive to certain rubbers & plastics?

 

that sucks who has done it because I was hoping to be the first

 

I hear the Evo is sick on E 85. You need to change the injectors and fuel pump from what I hear but you can run like 30lbs of boost safely. You would also have to retune the car like anything else you do to the Evo X If I'm wrong please let me know cause I don't want to be spreading false info.

This is totally not true. There was a test done on a regular car running E-85 for 185000 and the results were incredible. If I find the link I'll post it.

 

How exactly does E85 allow for more boost, and does it have any advantages such as cooler engine temperature? Would you need to run E85 exclusively in your car if you changed the fuel pump and injectors to allow for use of e85?

 

all i know is that e85 is equivalent to like 105 octane, which is like race gas, so yeah, you can run high boost all day

 

there was an article about e85 in australia a couple of months ago. the reason you can run higher boost on E85 (as i understand it) is because the combustion of methanol has a cooling effect on the engine temps, i.e. it doesn't burn at such a high temp thus the air flowing into the turbo is cooler - cooler air means you can compress more in thus the 30psi.

as far as running an X i believe that all it requires is a bigger fuel pump so as not to starve the engine. i can't base that on any diffenitive fact only hearsay. e85 is available in one state here in OZ and hopefully it will spread to others. if it does i'll be running my X on it.

feel free to correct me if i'm wrong

 

Since 1985 fuel has been mixed with at least 10% ethanol... so manufacturers just used seals/hoses that can withstand 100% ethanol content since it works just as well as 100% gasoline and is much cheaper than using a hybrid seal.

 

Do you have somewhere that this is written, not trying to call you out, but what is the deal with selling vehicles that are E85 capable if all vehicles can run it. I read that is mostly some seals that need to be replace in the fuel system because of the corrosive nature of E85.

Thanks.

 

Lots of good info here.

Apparently, it's lower risk than I thought, but not risk-free.

 

Fail. You need to check your facts on this, but it's 100% wrong. MTBE was used until a few years ago when it was fazed out for ethanol (simply because MTBE was getting into the ground water and was really bad for you).

Ethanol is highly corrosive. Some manufacturers (BMW mostly) continue to recommend not using E* gas. It also has less "bang" (BTU) than gas. And even worse, it causes strains on the fuel supply and is causing massive deforestation in Brazil (since they are clearing the rain forest to increase the land available for sugar cane supply). Producing ethanol takes more gas than it replaces as well. Even worse, transporting ethanol is a non trivial task and is requiring a major overhaul of the pipelining system in the US. Since the ethanol is added to the gas late in the process, the mixtures can be vastly off. Sometimes it's 3-4%, sometimes it's 50-60% (google it, news stations were starting to pick up on this this summer when gas was so much more expensive than ethanol).

And to make it EVEN worse, ethanol is hydroscopic, so as it sits at the tanks (everywhere, distributor, on the truck, at the station), it's picking up water. Water in your gas is baaaad juju.

E85 might sound like a great thing but as a replacement for normal gas it's a HORRIBLE idea (except in the short term because it's cheaper than gas [due to subsidies]).

Personally I go out of my way to purchase gas without ethanol (which is nearly impossible in the Dallas area). My car on gas with Ethanol feels slow and hesitates. On ethanol free gas, the car feels much stronger. Even 91 w/o ethanol feels better than 93 with 10% ethanol.



There is a X in Austin that's on E85 (blue, wingless). I'm sure he's on here.

 

In addition to Goofygrin's comment. On my CRX the ethanol mixed premium pre-detonated quite a bit sooner than straight 93 as well even at just 10%. I too don't care if shell thinks its a cleaner burning fuel. Keep that in mind if you're tuned on a particular gas.

 

Some guys on SCE (Socalevo.net) Love E85 ... It's "cheap race gas"

I am personally going to be running it on my X.

I've got an upgraded fuel pump, and 1000cc injectors, just waiting on the turbo.

We are hoping for over 500whp on an FP red.

E85 does burn faster then 91/93 octane, so if you are running it on stock boost, you will probably not see any gains, and sh!tty gas mileage. To reap the benefits of E85, you would need to be tuned for it. The only downfall so far, is I don't think the ECUtek has map switching yet, in case you can't run E85 for a couple fill ups.

I will post results once tuned.

Although I don't have an X, E85 probably has been the best thing I've done to my IX in picking up ridiculous power over pump 93 octane.
