from what i have seen on a few import "race cars" they use a different injector and pump, and thats all i could tell that was different, they told me it was actually cheaper for them to run alcohol for actual race cars than it was to keep running race gas, it has an awesome burning rate and runs soooo cold, i would love to see someone with an additional type injector setup with an alcohol resevoir on a street car, i have seen it done on the LS1s with nitrous, they have a seperate pump, tank, just for the alcohol...

let me know what you find
