Switching to E85, then pure alcohol.

Friend of mine and his dad just built an alch. distillery and are gona start running that pure. theve done the research and that its much cleaner burning and doesn't leave carbon deposits which is good and has a much higher octane % than gas. my only concern is how the stock fuel system will hold up.

if anyone can give me a few pointers on what would happen or any road blocks that would come up it would be very much appreciated.

you'll need to upgrade to a larger fuel pump and much larger injectors...your fuel economy will be absolutely rubbish...you need a custom tune...and I'm not sure if it's entirely possible to run our cars on pure alcohol

Pure will be hard starting in anything colder then 60*. I wouldn't do straight, you'll need at least 10% gasoline I would think.

Not to mention multiple maps and a way to adjust on the fly or between filling up when you might be out and run out of whats in the tank and what you are currently running isnt readily avaliable.

i may do a 50/50 of gas and alch. why is it that with E85 you get such bad mileage? thought it was supposed to be more efficient than gas

Plain and simple, you need more E85 to make the power. It's not more efficient, it higher octane. High octane (resists detonation) is technically LESS efficient then low octane, but you can run more boost and timing without knocking. E85 is basically 105 octane, so significant gains in power can be seen with the only downside being mileage. It also burns at a cooler temp, so it's actually easier on turbo and exhaust components, not to mention it's basically as clean un-catted as premium is through cat. If you average price per mile with the lower price of E85, it's about the same price

Even E85 cranks longer to start on colder days, so once again straight alchy is not the way to go for a DD.

Garage
If you live in a cold climate and you want to run straight alcohol, forget it. Cold temperature will require completely different maps than warm temperature and it'll be a nightmare to keep running in the cold.
