I have a single nozzle set up now and with street timing at 22* 22-23 lbs of boost I dont get any knock and O'2s in the Low 800's. Now when i switch to the race timing 26* and alky same boost I get a lil knock needless to say. I was wondering if going with the dual nozzle set up and throwing more alky at it if that would cure some of the knock? Or if Im just gonna have to run race gas 110. Opinions Thoughts?
