I don't mind any commments... help point me in the right direction if Im not already am.. plus makes me ask more questions. :) However, I still stand by my statement. This is because even with a fine mist of water vapour, there is still that volume that could have been occupied by the air/fuel mixture thus reducing volumetric efficiency... I mean.. you can even notice an increase in power just by polishing your intake manifold insides, which only causes a small increase in flow.As far as driving around on a hot sunny day and cool nights, well.. the key here is Mass air flow. On both days you will suck in the same volume of air.. but wait... volume is not equal mass.. that would be volume x density. So on a hot sunny day, you suck in the same amt of volume of air but density is low so overall mass flow is reduced. So you say that when you spray a fine mist of water, mass is the same while intake temperatures are reduced.. well that's exactly what happens.. but with water saturation, combustion temperatures drop and so does power..</blockquote>
