Injecting prior to turbo comp' impellers

[RICE RACING]

ff86, I have video with pressure transducers mounted in air and water feed through telemetry showing target droplet size happening at 7psi, I generally tell customers to switch it on at about 10psi+ and some drag C16 users operating at 36psi boost pressure tend to turn on the system at 20 to 22psi level.

Got a few users who inject into the end cap of the air filter and they don't report water loading of the element, probably to do with air flow rates, seems to be not an issue, but I am sure if you did just one pull and shut off everything off from an open throttle then you would see some evidence of water there.

So far as ideal spray position? my feeling is to inject into a chamber, this is what I tried to create on my own car, this so far seems to work best.
