aux injector placement

aux injector placement
dedicating this thread to discussions about the pros and cons of various aux. injector placements as i have heard varying placements with varying results.
as far as i have heard the injector should be located as close to the port opening as possible for maximum charge effects but who has actually tried different setups and noticed the different results? what have you run with and had good results?
personally i was thinking of placing them on the secondary runners just below the secondary injectors since the turbo leaves very little room to work with, the air velocity should take care pulling the mist in just fine i would guess.

Have a look at this site and you experiment with different injector locations and amounts (and also fluid types)....

Thanks for the link, awesome source.
So far, you are the only person that I have found in my research that has any sort of atomizer incorporated into their system, which I think is VERY IMPORTANT.
I know that you prefer pre-turbo injection. I was just curious. . .have you tried other injector placements with those atomizers? Any data there? I'm just curious because I'm scared to inject pre-turbo because it seems like it has to shorten the life of the turbo to some extent, maybe I'm just being overly cautious. . .any data on turbo lifetime with pre-turbo injection?
Thanks for the info

I only use this location (pre turbo) as it suits my system, I have not sampled the atomizer in other locations BUT it would not workin others since its air source is boost pressure and you need the differential (from atmospheric to engine) for it to work properly.
I am guilty of sticking with what I know I suppose.

I guess I fail to see how it wouldn't work anywhere else. . .couldn't you just run a line from the charge pipe or something to have it work elsewhere?
Forgive my lack of understanding, I've just never seen one of your systems.
thanks

Pressure against nozzel exits is the same as in charge pipe = no pressure difference = no air flow = no atomization
Since I use charge pipe pressure to deliver fluid and also as the air source means its suited from pre inlet ambient conditions, if you follow that logic?
TO use the atomizer in charge pipe you would need another higher pressure air source which is very complex and kinda counter productive.

thanks for the info, the pre-turbo route does make sense but i have heard about condensation in the intercooler if you run anything pre IC but this would probably be drown down a bit by running pre-turbo. the only thing that concers me is compressor blade wear, it would be more visibly obviously with water but what about alky and meth? but then again i suppose those would be another discussion for different placements since water, alky and meth all have different cooling capacities and since meth is combustible that might not be a great idea where a 50% alky might work just fine(non flammable mixture).

I hate BOV's !!! *dont get me started*
First things I tore of my SP RX7, have lap record by 1.5+sec for OEM twins car so maybe its cause I dont run those silly devices
Yes I have been told I am different before

darn Equator!
north of the Equator your mind spins in one direction , south of the Equator it spins the opposite direction!! younno might be more to it than we know.
