has anyone ever measured the charged intake temp

Hope to know soon. The next 'version' of my LIM will have a thermocouple installed for this very purpose. Along with 2 other fairly major changes. I need that sensor now so that I can characterize the drop in boost charge temperature with the water injection running.
Greyhare (co-worker of mine, membe here, drives a Neuspeed-M45 Eaton-Equipped VW Jetta) has taken some data that might be somewhat relevant to our application. I'll get him to post in here today with his findings.

On a ~50* night with a heavy mist I hit 130*f at 13psi boost. My blower is spinning at 15522rpm at red line.
Water injection drops temps by about 20*. The actual drop is probably more but my IAT is only 2" after the water nozzle, there is another 10" to the intake ports.
Without water I see as much as 9.5* KR, with water I see 1* or less on random cylinders.

Keep in mind that Mike'* data is a general guide. A typical summer day will be a much bigger change from ambient outside air temps (IAT) and boost charge temps.

My numbers will not directly translate but the trends should.
