I currently running WI using 4mm and 7mm aquamist nozzles together. I am using washer fluid [30% methanol] starting at 15# boost. This has reduced my knock sum from 25 to 10 at 20#, but I can't feel any increase in power during WI. Many of the Buick GN drivers are using 100% denatured alcohol injection and 93 oct. gas claiming this works as good as race fuel.
Has anyone gone this route? If so how does alky work?
