e85, and a few other questions
yes i searched and got some info on this but here we go...
OK, E85 (85% ethenol, 15% Gas) has been slowly being pushed in the us.
Well, I live on the border of nebraska and iowa, two of the highest corn and ethenol producing states in the country and within a 5 mile radius of my house there are 3 gas stations carrying e85. the price of gas station A(which is in nebraska) is 2.65, gas station b(iowa) is 2.69-- actually it was right across the street from where i get gas and i paid 2.58 for 92(up to 10% ethenol though) and then a few blocks down the road gas station C is selling e85 for 2.19 a gallon!
hmm... i thought to myself what if after i finish upping my fuel system and engine management if i prepared it to run e85 also.
now i get the fact that there are differences in e85 and gas, and i understand that gas milage would decrease, but who needs gas milage when you drive a rotary(and for some weird reason i have been getting 20-26 mpg over the last 1000 miles) so i can take a hit for more performance(in more ways than one) for around 10mpg.
being that race gas around here (100 octane and 110) is going upwards of 6-7$ a gallon, i would much rather run clean with ethenol, even if it did cost me a little more in the end, plus being an alcohol, it would run cooler, and even though it would use more gas, wouldnt it give more power?
so what this comes down to is, what would i have to do to my car to be able to pump in e85?
but, i would also like to run if i had to 92 and 110-114 if i wanted...
thanks and have a great day...
also, if anyone has any experience in this stuff, can you pm me so i can discuss it with you a little more

First off the entire fuel system (tank, hoses, injectors, breathers etc) has to be able to handle e85 as it's highly corrosive. If you wanted to be able to run gasoline as well you'd also need the proper sensors and ecu capabilities for the vehicle to know what the content of its fuel tank is and therefore tune the engine accordingly. Long story short the conversion wouldn't make sense from a money standpoint.

Damon is right. The fuel supply system must be made of materials that can tolerate the high corrossiveness of ethanol.
For example, Ford FFV vehicles have stainless steel components such as fuel pumps injector parts and fuel lines to resist corrosion.
Also as Damon said, there is a sensor in the fuel system to detect the type of fuel in the tank to alert the fuel controller in the ecm to adjust the delivery rate.
A conversion makes no economic sense. I'm told the FFV stainless pump for the Taurus was $2200 approx.

From what you're saying E85 is 20% cheaper. Keep in mind that it gets about 65% of the mileage regular gas does. Here's the familiar Car and Driver graphic:

ok, on the system of what type of gas is being used, i would just have different tunes on the megasquirt ems
and also, what about using AN lines for the fuel system...
so it would eat at the fuel tank, fuel pump, and what about a aftermarket fuel pressure regulator, and fuel injectors?

fuel tank cap
fuel filler tube
fuel tank
fuel tank breathers and vapor recovery
fuel pump
fuel hoses
fuel injectors
all seals in fuel system
all parts and seals downstream of fuel injectors in the intake manifold
all emissions controls and valves
etc...
...and in the case of a rotary we probably don't want to know what ethanol does to the rubber seals inside the engine which seal the combustion chamber
And that doesn't even cover the electronics. This is why you don't see backyard E85 conversions; it makes no sense. Something like biodiesel for instance doesn't have these issues.

E85 is a fad without government subsidies is would cost significantly more the normal gas. Hell part of reason gas prices went up was because of a government mandate to replace a petroleum additive with a alcohol based version. At some point when the truth is accepted that this is just another welfare project for the agriculture industry it will go cease to be produced in any significant quantity.

as far as i know.. which isnt far... e85 alone will not help with performance.. e85 has a octane rating of 100-110. so for your average rx7 you would probably loose power unless your are goin to increase boost..

Someone posted a few months back about converting their FD to run on E85... he seemed to be pleased with the results. I'll see if I can find a link.

E85 is more than just higher octane though and as mentiond above has it's own fair share of problems in other aspects.

We have 90 Miata on e85 for the past 3 months
We have e85 running in a 1990 Miata, The power has been great, MPG very good also, The Change over took less than 30 minutes, the Kit was Flextek unit ask for Allen, Now we have a Flex Fuel Miata. The only Problem is the e85 Gas Station is 120 Miles away, But that is about to change will be getting a 500 Gallon tank for home and 1000 gallon for work and buying @ wholesale Price $1.55 a gallon
