After I go though at least 50lt of injection fluid I will post up my own comp wheel picture irrespective of what it may look like :lol:

Been following your results for some time now. How much pressure (water and air) do you use to atomize the water so well?
So all the talk of injecting water straight into the nut of the turbo is not the ideal setup in your opinion? Wouldn't spraying the water towards the filter cause saturatuion of the air filter and excessive puddling on the inside of the pipe?

Like so...
Here is a video of the setup in action.

And here's a video of one of the pulls:
YouTube - Engine Dyno Pull @ Street & Strip
TEST RESULTS
Set-up specifics: The engine on the dyno was a relatively stock 2.3L Ford engine out of a late 80's Thunderbird. The turbo was a Holset HX-35 running at 22-23 psi. The engine was producing roughly 450HP and 389 ft/lb torque. The nozzles were all mounted in the same location throughout the tests - about 4" away from the compressor nut. The pump used was the Devil's Own 250 psi pump.
Here are the results that we gathered:
No injection;
