temp and mass flow
I don't have the resources to do the thermocouple test, but I know the result. Several folks have run similar tests and the temp drop is on the order of 30 - 40 deg F for common WI injection rates. For straight water injection with no alcohol the temp drop will be about 20 -30 deg F, depending on the relative humidity.
As far as the boost, I already know the answer to that question, My electronic boost controller has a peak hold feature that tells me the maximum boost achieved on a given run. I had to turn down my boost controller to avoid over boosting after I installed the pre-compressor injection.
The mass flow through a centrifugal compressor varies directly with the absolute temperature of the inlet air. Lower the inlet temperature, mass flow goes up. Its the nature of the beast.
