Noob to SRT6/SLK32's here

At 750cfm intake (@6200rpm) (excluding H2Ovap) and 14.5psi boost, I calculate to drop your AIT's by 50F (32C) you'd need 6ml/sec (about 1pint every minute and a half) of injection (water only at 2250kJ/kg Hvap), however as you probably know, this generates H2O vapour (32cfm) which dilutes your O2 down from 21vol% to the low 19vol% levels - with obvious consequences.

I havent analysed the reactions in the cylinder fire - but I think I recall the H2O is a power neutral addition to the fire, since whatever it gets involved in - it should end up as H2O out the exhaust - but not sure on any total gain in this regard.

How much water you adding for your dT on your AIT's?
