running juice and alky there is not much of a gain its more of a loss..from what i under stand.thats why u dont see pro mods and 10.5 cars run alky

but in a n/a engine alky makes 7hp per ever 100..so if your engine makes 1000hp n/a on gas it will make 1070hp on alky..

now with alky u have to run a lube in it or u will dry out your seals and your cylenders will rust..alot of people will spray wd40 or somthing down the carb and kill the ignotion and just rotate the engine when putting the car up..u also will run cooler but u burn twice the amount of fuel as u would with gas...alky is around 118-120 octane depending on where u get it from.
