buy xylene. you can get it at sherwin-williams for $36/5gallon can. the more you buy, the bigger the discount. available at about ANY sherwin-williams store... its likely that S-W is more common than a race-track pump. if you want, you can mix it in a 33% mix w/ a little bottle of MMO and get 106 octane. or you can run it straight and get 117 octane.. you can easily monitor your fuel level... but untill you put a tank level guage in your alky resivoir, youll never know how much is left. id rather not find out the hardway that im out of alky... hence knocking and pulling timing. no knock is better than some knock.
It its just putting yourself in a situation that you dont need to be in. save that money and invest it in some larger injectors or a nice FMIC-tercooler and hard pipes. that would be the responsible thing. these little additives and things that cause dependance like nitrous and alky/h20 injection are just problems waiting to occur. its alot safer to run low on gas and say "hey, i better stop at the Shell" than "Oh shit! I better let out of it and let this ricer with nitrous win... its knockin like a Mofo. I bet my damn alky tank is empty. Goddammit, i KNEW chris was right!" 
seriously, dont create dependance on an item/product/chemical that you dont need to.
If you are knocking, find out why. Fix the cause of the problem, not the result of the problem. Even with alky, youre not resolving the issue of a highly heated intake charge. hell, even a larger fuel system would just take the place of alky injection. the REAL solution is to get a bigger turbo that is more efficient at the power leve/airflow you desire or a bigger intercooler that will counteract the inefficiency of your turbo.
besides, i NEVER ever said alky wasnt proven. i Know people have gone fast with it... but people have gone fast with 2.3L CRX's, Log manifolds and Dry shots... but that doesnt mean its a good fuckin idea. your money could be better-invested elsewhere.
Last time I checked people who actually use alki are smart enough to make sure they have a full jug of it in their car before they go out on a night full of racing. The fact is that it is an alternative for race gas. You never answered my question where you stated "oh crap my alki is empty" what about when you go "oh crap im out of race gas" and you cant get any within miles or untill a shop opens on monday? Alki also healps keep carbin buildup out of the motor and helps the motor flow better. Since when is using something to reduce intake temps a band aid? That's like saying using an fmic is a band aid. There was a white dsm in gainesville running alki injection, full stock motor, traping 125mph in the 1/4mile and loged over 1000 passes and never broke. It's so not safe
Now he has a dsm that is running 133mph fully stock motor, I'm going to go out on a limb and say thats the fastest stock motor dsm ever. I better go tell him to stop using alki cause it's just a band aid and that his buschur race core fmic, turbonetics t4 t-series turbo and aem ems arent good enough parts to run without alki. Does this also mean cars that run on only alki are just bandaid cars? Last time I checked running alki that is made for cars in injection is better then using ace hardware chemicals that will destroy your injectors
I think you have a big misconseption of people who use alki that they are getting knock and just throw on alki to get rid of it. I am talking about people who use and tune with alki, and could throw in race gas and turn off the alki and get the same results and no knocking, but using pump gas and alki is alot cheaper.
