Installing a direct port Water injection., Help needed to place the nozzles... Options

[snakeloa]

Hello everybody,

i got a few questions again and might need some help

I ordered a "Direct Port Water injection" from here:
Enginerunup

Now i have to see where i can mount the nozzles on my intake manifold....

Well my mechanic wants to place them at the bottom end:


But i think that might affect the full atomization process?!?
As it is a direct port WI it should be one nozzle per runner. But where. And as far as i heard there is not much space to place them!!!

Here is a pic of a ST205 engine:

and especially of the runners



So where would you place these nozzels? And keep in mind that the nozzles have these huge checkvalves... so they are quite big.

And where is ourAir Intake Temperature Sensor?

cheers Joerg

water injection is a form of chemical intercooling system really to put it simple....it cools the intake charge in high boost applications so that you prevent detonation (i have minimal understanding of this but thats my general idea of it)
direct injection means that it fires directly to the combustion chambers via the intake runners (4 / 1 per runner) indirect would be spraying 1 nozzle into the intake tube (not very accurate and even, less tunability)

where your mechanic seams to have it looks ok...i might set them a little farther up the runner by an inch or so just to insure there is enough metal near the manifold to prevent warping or cracking....
but along the backside of the runners seams to have the most room
