Trying out E85, anyone else? Seems to be debate on conversion
Do I need to convert any fuel lines, fuel rails, FPR, or fuel tanks to do this safely? Some people say yes, some people say no. Feel free to make this a debate. If so what's the cost? Right now it actually costs more for E85 due to mileage loss but I'm running with no cats so that could help the pollution and stop the smoking at startup. Today $2.76 E85, $2.98 regular, or $3.16 premium. But hopefully if enough people start using it the price will drop. I've got a farmer nearby that is interested in making his own on 5 acres but he's got regular GMC trucks, but then again I'm not usually boosting (stock turbo is maxed as far as boost on a large streetport but I'm usually being outaccellerated but everyone so they must floor it or something) so I'm probably losing power too.
I decided to break down and give E85 a try in the T2 with Microtech LT-8 and Dynojet wideband. I put in a 50/50 mixture of E85 with premium today and added 15% to the mix trim setting. I probably should have started with 25% but too late now.
I have blueprinted primary injectors with Marren secondaries for now with RC Engineering secondaries to drop in and place the Marren's into the primary once I upgrade the turbo. Also a Walboro 255LPH pump. The rubber fuel lines are new and the vacuum lines are Hose Techniques silicone and the engine has the Rotary Aviation rebuild kit.

Never did it in my 7. I did it in my DSM plenty of times, generally 50/50 and tune for no knock. Of course, this is back when E85 was 1.50 a gallon and gas was 2.50. Here in san diego E85 price has exceeded gasoline so I don't feel a need to try and make the 7 run right on it. I was more into a cheaper, alternative fuel than the octane rating.
On the DSM, I had stock fuel tank, stock fuel lines, stock aluminum fuel rail. No problems.

You need to convert all fuel lines/fuel pump/injectors over to E85 safe plastics/rubbers/metals
Then you need bigger fuel injectors and a method to manipulate the fuel tables because E85 needs more to be injected to reach the same levels as gas.
So some dyno time will be needed to get your base maps down.
There has also been some debate on the alcohol washing away lubricants in the combustion chamber.

I can't wait for gas to get to $5 a gallon!

E85 or other current, alternative fuels will not satisfy growing US demand for oil / gasoline. Sorry, we're all screwed. Enjoy cheap gas while it lasts.

obviously youve never been to Iowa. we have so much f**king corn, most of it gets thrown away. the problem is that refining it takes so much energy, it hardly makes it worth it. so lack of corn isnt the problem there, chief.

E85 is the worst push ever. It's not a green energy at all. The fertilizers used to grow the corn are derived from petroleum. In addition to that you may not be producing a lot of CO2 but you would be seriously offsetting the nitrogen cycle which has serious repercussions as well.

Again you are right, ethanol has a negative EROEI (Energy Returned on Energy Invested). So even if there was enough corn in the world (there isn't) we would have to spend more energy / $$$ producing ethanol (using current methods) than we could obtain by burning it in our vehicles. Not to mention the fact that we wouldn't have enough corn left over to feed ourselves...

"You need to convert all fuel lines/fuel pump/injectors over to E85 safe plastics/rubbers/metals"
What about the fuel rail? And any idea where to get these parts/how much they will cost?
If I stayed at a 50/50 mixture would it still do damage and how long would it take? I found a site where I guy has been running E85 in a WRX for 3 years with no problems yet, don't mean there isn't any. Then there is supposed to be a guy that's been running it for like 30 years and just changing out fuel filters. How long would the stock system last? Enough to save up for the switchover? And some guy was saying usually engineers overdesign for chemical resistance so if it can run on 10% ethenol it should run on much higher concentrations, which is logical but still theory.
I ran it for a day on the mix and I do like it, my clothes no longer smell of car, much less smoking at start up, and hopefully no more buildup on the bumper above the exhaust tips. But if it's going to damage the car it's not worth it, I've got at least 10k in mods/rebuild and the car has less then 80k on the odometer.

-Aluminum corrodes in the presence of alcohol
-The plating on the mild steel fuel lines as well as the mils steel it self corrodes in the presence of alcohol
-The lining of the tank is not sufficient for long term ethanol use
-Aluminum is electrically conductive (gasoline is not) so in short NO IN TANK FUEL PUMP SHOULD BE USED.
-All rubber needs to be rated for 100% alcohol use, organic rubbers (like the stuff sold at the parts store) very quickly degrade in the presence of alcohols.

that stinks, so even at 50% it'll be a problem?
I'm serious about this so where can I get parts for the conversion? Might have to save up but not like I don't waste money on the car already.
"Hydrogen owns all", show me how to run it and store it, I'm all for it. Maybe I'll just say screw it and do a Paul Pantone GEET conversion, that probably don't work with turbo EFI even if it does work though.

Not only that, it will bring the economy way up in the aggriculture world. It has alot of benefits you obviously dont know about.
E85 is "a great alternative" in the eyes of the ignorant or politically motivated.
The sad fact is that if we geared domestic agriculture toward wholesale alternative fuel production the price of feed stock would drastically increase. Some of this is already occurring, check the price of meat this coming grilling season. When it comes to E85, the costs far outweigh the benefits at this time.

During its growth to maturity, the cane stalk absorbs the same amount of carbon dioxide from the atmosphere as is eventually emitted during combustion of the ethanol distilled from its juices.
But this is not so for ethanol made from corn in the United States or wheat in Europe. These primary materials must first be turned into sugars before fermentation,
which requires the use of extra fossil fuels and adds to carbon gasses emitted in the production process.

At this point, ANYTHING we do to ease the strain on fossil fuels could be a blessing.

Nothing else you are saying is groundbreaking. The problem is, alcohol based fuels here in the US are in their infancy, and they may not solve the problem but at least someone is trying a solution instead of saying "we are screwed".

My argument is that E85 is not a viable alternative and converting an inefficient rotary engine in an 80s car to run on E85 is a huge waste of time.

E85 can never replace the power/price of gas BUT it's not about price/effectiveness.
It's about the fact that is burns VERY clean.
It's a trade off. You lose some power but you gain a cleaner enviroment.
As for corn... Been over that in other threads. Almost ANY sugar based organic matter can be used for ethanol production.
A great example would be infected corn crops which can't be sold can be used.
Gas has become the wonder fuel of our era. It's going to be very hard to replace and maybe we never will. These are all second choices which help benefit our enviroment.

The arguments would be so much easier to address if everyone cited their sources.
And everyone seems to have left out electricity, the real "green" future of the automobile is the electric car. So we need more focus on Nuclear power, high capacity battery technology, solar energy collection and high efficiency electrical components.
E85 might be an important stepping stone to break away from the Middle East, Hydrogen may be the best possible replacement for the gasoline engine, but almost anything at this point is better than nothing.
Agree/disagree?
