Doe anyone have any experience using a mix of ethanol and gas (say 50:50) in a street driven boosted engine?

I know that in order to run the E85 Fuel available today, you need to have a modified fuel system, but in weaker concentrations (50:50, or 30:70) what kind of responses would a boosted engine give to this fuel mix.

Its just kind of a pipedream I' m having right now, I dont except too many ppl out there to have done somehting like this, but I just thought I would ask.

 

bump for info....does ethanol have a higher octane level than regular premium gas? I know its more corrosive on rubber fittings in the fuel system.....

It has a WAY higher octane rating. E85 is like 100+ octane. Someone on here made a post about ethanol, and said that all the myths about rubber fittings and seals was false.

Ethanol also takes a different air fuel ratio to be perfect, I don't exactly know all of the info, you will have to search for the post

I ran a mix of 30% e85 on my stock b16 just to see what would happen, and it ran perfectly fine. Plus I saved a buck or two at the pump

 

Ethanol isn't corrosive like Methanol is, and even an 85% mix would be plenty to make a TON of power in a turbo car. Do some research, Ethanol is a great fuel for a high hp street car!

 

Ethanol is an ‘oxygenated fuel’. It’ll lean out you’re a/f mixture by about .5 on a 10% ethanol/petrol mix (re pump gas). Ie: you’ll want to add 3-5% more fuel.

On a 50-50 mixture you'd need to add a lot more fuel. Something like 25% or more.

 

I'm actually going to start testing ethanol soon to see if I can get a good basemap for a d16z6 soon.

Are you guys sure ethanol isn't corrosive on rubber lines? My buddies dad said that new fuel lines were one of the few things that would need to be changed to run ethanol.

Imagine, cheaper gas w/ higher "octane" rating. Soon we're going to have 800+ HP street cars running on pump gas.

I hope it comes to Maryland soon.

 

so essentially this isn't a 50/50 mixture is it?

 

wade you live out in the country, go out there and find some moonshine

 

thanks dick!

 

Ethanol is corrosive to rubber.

Your MPG will go down also, because it also consume more per pound than gasoline.

petroleums burning sucks, alchohols teh bettar !

Also, doesn't hurt to have a better ignition system to use with ethanol

 

so on boost, would ethanol do better than gasoline? It would be interesting to put this to a test! I have to write a paper for my English 120 class and i think i'm going to write about this....more info!!

Do you think any tuner would tune my GSR on E85??

I dont know about the tuner thing, it's worth a try.

Better detonation resistance, cooler running and a clean *** combustion chamber.

I remember my friend telling me there is some program where the goverment pays you to run alternative fuels.

 

well i'm going to go out on a limb and call my tuner....i'm going to sound like an idiot!

We need some tuner's opinions on this thread!!

 

i just called him and he didn't seem to think that it would be a great idea. He said that he's thought of it, but doesn't think it will work for a Honda application. I'm sure it can be done, but it would take extensive R&D to do it.......thoughts???

R&D has been done all it takes is a little search on yahoo and you'll see all the people who have tried it.

Dont use oem filter paper element, oem injector o rings are fine, Run stainless elements fuel filters, use steel hardline from you tank to engine bay, for flex use teflon hose(http://www.bakerprecision.com/aqp9.htm), and last but not least you gotta use anodized components anywhere ethanol can come in contact with metal.


Here's a good link.

detination fighter i can't wait for it to come my way

 

Commercial grade Ethanol (E85) is very corrosive to a standard fuel system. I wrote a research paper on it last semester and without specialized fuel lines, injectors, fuel tank, etc, it will corrode your fuel system.

This is why I was thinking that maybe a more diluted mixture (50:50 or 60:40) could be run through a stock fuel system.

Sweet, so has anyone here actually performed all these upgrades?

 

GM has on the majority of their new vehicles

Not quite the answer I was looking for. But while your on that topic, Ford, Isuzu, Mazda, Mercedes, Mercury, and Nissan also have a decent lineup of vehicles that have those up grades.

Now, back to my real question, has anyone one here performed these upgrades to their own car?

I'm gearing up for running methanol almost the same.

What most of the SAE CSC guys found was that with E85 they could run more timing than with E15, but needed more fuel. So they made more power, but needed more fuel to do it.

SOMEONE DID A POST ON THIS ABOUT 4 MONTHS AGO AND IT HAD HOW TO GO FROM GAS TO TO ETHANOL AND HAD A CHART FOR A/F RATIO. I DID A SEARCH AND CANT FIND IT.
