You should ask Richard L.
Post this question in the Water/Alky injection forum.

 

yeah direct port is the best.... however, you may need 2 pumps for best pressure

 

Hiheatevo,

I am not an engineer nor one of the person that built the alky kits but let me put it this way, if you install the nozzle on the exit of the intercooler by the time it reaches the Throtle body the temp is going to go up.

Then also you have the BOV disturbing the path and flow of the air flowing from the intercooler to the throtle body.

Ideally you want independent nozzles right at the mouth of each intake manifold tubing. Unfortunately that cost a lot and you have to custom build it. Anywere from 4-8" to the throtle body should work the best for most kits , normally right after the last bent prior to the throtle body .

Thanks Carlos, I plan to mount mine right after the apex of the last bend into the TB but still durring the bend, I feel the cross spray may help homogenize.
