I have a DIY alcohol injection setup that I have used for several years. I use a NOS nozzle located in the up pipe about 8 inches in front of the throttle body. I originally ran the nozzle pointed toward the intercooler. My logic was that if the alcohol was sprayed into the oncoming air it would mix more uniformly with the air before it reached the intake plenum. About a year ago I turned the nozzle 180* so that it now sprays toward the throttle body. My logic with this orientation is that the alcohol will reach the plenum faster. Truth is I have not noticed a difference in performance or effect from either orientation. I have wondered if there are opinions and experiences I could consider with regard to the nozzle orientation?????
BTW, I do have a power plate installed.
