pre-compressor nozzle location for TT
#3
The objective is to make an arrangement to send atomized water individually to each compressor. The path to the secondary compressor is opened only after transition and when the two turbo compressors work in parallel. You can see the solenoid valve mounted on the side.

Thanks Howard.
The objective is to measure the effectiveness of evaporative cooling inside the compressor. Hope those PJ nozzles will help...
My plan is to take T measurements at the air box and at the compressor out, pre I/C and compare with and w/o water. I could not find good data so I will be trying generating my own... we'll see...

My initial thought was using one solenoid valve only to align the "secondary water rail", to be actuated by a primary-secondary transition signal, as sketched below.
Today I had some siphoning at the "primary nozzle" after shutting down the pump, but the water tank was sitting high well above the nozzle. I'll have to take some measurement in the car and see if the nozzle will be high enough to break the vacuum. If not, I will need one more valve.
Transition signal below (taken from the PFC by adding a very high impedance Solid State Relay, not to add any meaningful current to the pin driver):
If I will have a siphoning issue, I will run the power to the WI solenoid through the same pressure switch I will use to start/shut the pump.

Although in the case of a single turbo the tcn solenoids would be removed so i imagine you could run about any small solenoid or relay directly from the pin. Are there any pins on the pfc that are boost activated? The one we have been refering to would make a good rpm switch, anything that would make a good boost switch? The voltage switch that was posted in the other thread looks pretty cool.

Just try to keep the main mass of those things out of the air streem to keep the air flow numbers high. Those turbos blow a lot better than they suck...
Next time I'm in Summit we can put them on the flow bench and see what it does for the airflow

Thanks Aaron. Yes, I thought about that. To minimize obstruction, I placed the water rails a little behind and used extensions to bring the nozzles at the mouth of the hose openings, without sticking inside them. It shows somehow in the second pic. Nozzle jet is about 90 deg and wanted to send the mist inside the hoses, not inside the box. It's the best compromise I could think of...

I have been wanting to move my WI pre turbo. Right now its in the elbow but I have been struggling to think of a way to make the second nozzle come on.
Good luck and thanks for sharing!
