Anyone here running a car on E85 Bio-ethanol?

[chris@torque of the devil]

Just wondered, have contemplated using it when (more like "if" i get time)my new engine gets built, just wondered if any of you guys are using it already.

Is that the high octane stuff?

 

I think Dave Colledge is from Retro Ford.

 

At least I think he gave it a go.

All i understand is,you need to put more in to get the right A/F ratio.

 

I was thinking of setting a map up for this with my car............when i get round to that part ha ha

Think this is true - doesn't the oxygen come out of the alcohol as it breaks down under the heat / pressure allowing more fuel to be burnt?

It's not cheap , eats your fuel lines etc , needs a bespoke map for the engine to run properly + you'll need much more of it to make full power so if your car does 20 mpg on proper petrol it will now do 10 mpg . The above are rumours but come from a good source so we'll see

gaz is right it costs more than normal petrol there is a softer mix called E10 (the number stands for the content of enthanol in %)

 

but im not sure if thats going on sale here - i did a report on sustainable fuels last year

 

Im looking into LPG when the cortina is doenas its a higer octane and 46p a litre and apparently it isnt going to be taxed til 2012 the down side is i will need another ECU and the tanks are made from cast iron

I've driven an ethanol focus & I thought it as great, it was only a 1.8 but felt quicker than a normal 1.8. It was obviously built to run on ethanol rather than converted but the mpg was good

He did. Got an extra 13 bhp at the top end after a remap.

LPG is high octane but burns slower than petrol (or something like that) so you get less power from it . My mates got an LPG BMW M5 and he reckons it goes like an old donkey when on the LPG

I have heard of an expression "calorific value" and suspect it's more likely that that affects the power than the octane value. If it was octane I suspect adding Timing would correct for it, I think it's not giving off the heat energy.
