Powerwise I did not make any feelable difference comparted to direct port injection with similar flow. I injected 300ml/min.
The sound of the supercharger changes a bit. You can hear more of a noise. Intake asir temps drop to ambient using 50/50 water methanol.
The nozzle was positioned about 5" away from the intake that was S-shaped. I positioned in a way it would not pool on a wall.
