does anyone know if and what the effects of running a Land Rover on 100% ratio of Alcohol is. Can it be done?
Running Land Rover on 100% Alcohol

- Start date
I do stupid things and damage my truck when I run my Rover on 100% alcohol. Oh wait, that's now what you mean is it.

I have repeatedly run my truck on E 42.5. I cannot tell the difference, BUT, my fuel economy falls by about 20%.
Well, the trouble is, getting 100% ethyl alcohol is difficult - and expensive. Back when I was working at the hospital lab, we used to use ethanol as a reagent in several test procedures. USP-grade, 95% ethanol or 190 proof wasn't too expensive (no excise tax), but the 100% or 200 proof stuff was like ten times more expensive. Alcohol is quite hygroscopic and sucks moisture out of the environment - which is the biggest concern with alcohol-enhanced fuels today: water in the fuel.
I would imagine that water would be bad news for injectors, but not so bad in a carbureated vehicle. A Series Rover could be set up to run quite happily on alcohol (with a somewhat reduced power output) but I don't think the V-8 would like it much.

Ethanol in concentrations over 95% is made from a complicated process beginning with of all things, crude oil or benzene.
Alcohol forms azeotropes with water that are near-impossible to break to increase the concentration. This is a good thing as it will sequester wate rin fuel systems-that's why fuel line deicers are usually methanol.
95% reagent alcohol is often denatured with aviation fuel!
You will probably screw your truck up. Alcohol is very corrosive with aluminum, which is why you see plastic intake manifolds all over the place. It will erode the inside of an aluminum intake manifold. Not to mention probably screwing up seals in the truck fuel system, because they aren't designed for alcohol.

Exactly, in the manufacturing process to acheive a 200 proof label, read as >99.5% pure. A true 100.0% alcohol can not be made as trace chemicals are used to force azeotropic bonds to release the H2O. However these trace chemicals, benzene, acetone, and various ketones are left behind which form the remaining 0.5% or less.
This is all part of the denaturing process, removing the water, thus making the alcohol undrinkable often through the addition of methanol, wood alcohol. Not safe to drink I should say, unless your already blind.

And you thought those classes would never come in handy.
Welcome to the world of chemisrty, I do it everyday. If only I would have paid more attention to grammar, my reports and methods wouldn't get so chopped up. My third grade grammar skills make our secretary pull her hair out.
Yesterday, I submitted a 83 page report. I had a 132 word sentence in there, she about fainted.:rofl:
We were busy experimenting with "kitchen chemistry" - you know, those brownies that would make you smile all afternoon...ptschram said:
I remember learning avegadro's number, but when I found out avegadro wasn't that hottie in the front row, I promptly forgot it. dude.
it was a slightly different environment, going to high school in the '70s.
Halfway through the year, my chem teacher was out for about 2 weeks. He came back with false teeth. Turns out he had gotten into a fight at a bar, and got hit in the mouth with a brick. That musta hurt.
