Here's about all I know about alcohol, in just a couple of lines:
You will need about twice the volume of alcohol that you do gasoline, so you have to have a fuel system that will feed it.
A common problem with switching to alcohol on a carburated motor is it leaning out on the top end. The logical thing to do is to richen the secondaries with bigger jets. This is where guys start pulling their hair, because the problem just gets worse. What's really happening is the fuel bowls are running dry because the bigger jets required for alcohol pull more liquid out of the bowl than the neddle valve can let in to replace it.

Three solutions that I know of:
1) Multiple carbs. A whole other set of problems.
2) Fuel injection. $$$s
3) PSI Dual Neddle Valve/Dual Float/Higher Volume float bowls. Neat set up.

One other option that I'm considering: Run E85 instead of racing alcohol. Much cheaper than racing gas or racing alcohol. Will run in high compression engines and requires fewer modifications to your fuel systems. Start by looking here: http://www.raceone85.com/

What ever you decide, good luck.

Drifter makes very good points. I have seen some guys make the switch and do very well with the alky, and others that didnt gain a thing but their stuff ran cooler. There is no cut and dried answer if it will be an imporvement over what you have now. Let us know what you do and how things go. LATER, Apache

maintenance! I have played with alky for quite awhile in the sprint cars and midgets and you need to spend alot of time doing maintenance if you want to keep your stuff clean and working right!
I have never used it in a carb only injection but i can tell you they are right about using much more alky then gas.
Also your compression might be a little low?
with injection you really put alot of fuel through the system so you need really good pump/pump's and big fuel line and return line.
then there is the whole barrel valve and pills and by passes? :smt002

i forgot make sure before you put alky in the tank you pull any of the foam you may have in there or you will be picking little black chunks of it out of you whole system.
We ran 3 of the micro filters on our system to keep stuff out of the fuel system.

Methanol is alcohol. If you run a good top end lube in your fuel, you don't have to worry about all of the problems everyone is going to say you will have. The fuel system in my car is never drained, and my lines, fittings, nozzles and barrel valve still look good. And thats even after sitting all winter. Like others have said, you will use almost twice as much alochol as you would gas, the motor will run cooler down track, and it will also take longer to warm up if you don't have a method to lean the motor out. And yes, the car will leave harder on alcohol.
