Something about having too much water in the combustion chamber to vaporize, extra water increasing the dynamic compression, corrosion of valve seats and guides, etc.

Re: Water Injection 2007
Spraying water outside the IM, and allowing "air flow" to distribute the water leads to a very uneven distribution of water. The water droplets have more mass, and therefore inertia, than air molecules... air will whip around and follow the path of least resistance pretty well, but water thrown towards one end of a manifold with tend to enter the cylinders on that end of the manifold. Cooling only part of your engine is pretty gay.

Re: Water Injection 2007
I stepped up to a m5 nozzle. Running more of a 50/50 mix meth/water. What a difference.... It feels much much better! Call it gay, but it works. Theres probably only 20,000 people who have done it, ran it for a long time and not had any problems.

Re: Water Injection 2007
The assertion that water injected in the intake manifold does not have time to cool the air before the air enters the cylinder is bunk. In a diesel , some of the diesel fuel has time to vaporize when its injected ( NACA-report-435 http://naca.central.cranfield.ac.uk/...report-435.pdf ) before it ignites. So therefore water has plenty of time for part of it to vaporize before it leaves the intake manifold. Since the vaporization requires energy and the only energy available is heat from the surrounding air then the temperature of the air must drop.
Although time is a factor to the degree of how much cooling takes place, so are initial air temp, how fine the mist droplets are, and the initial temp of the water as well as other factors.

Do you know that water has a lower boiling point than diesel?

Do you know what the specific heat is of diesel? To make this argument relevant, what about gasoline? Do you know what the specific heat is of water? Also, please enlighten us as to what the the "boiling point" of diesel is. You done yet? Now shut the ---- up.
