Next, it was time to test and adjust the nozzles. We stuck a nozzle to the end of our HPS hose.
We hit the intercooler sprayer button a few times and set the nozzle adjustment screws for a pretty high flow.
Next, we drilled some mounting holes for the nozzles. We made sure that they were positioned not to hit our bumper beam.
Next, the Nozzles were installed.

so i have a GRB rally car and my intercooler spray is connected to an indicator relay so when it is activated, it sprays intermittently….could be something to think abot
I wonder if the spray pattern as well as atomization matters? The picture shows a rather concentrated stream into the FMIC. Does a finer mist mean more surface area, and more effective cooling?
Probably doesn’t matter a lot at speed, we wanted the spray to go through the IC and hit the radiator too. Mostly chose those nozzles because ease of install too.
any proof this actually works? wouldn’t it be better to just use water injection?
The factory uses this system, this is just re-enabling it for a front mount IC instead of the OEM top mount. The WRC cars used it so the factory added it to the production cars. Water injection is something totally different
The way the sprayers are set-up on your vehicle will do next to nothing…
The idea is that the water spray system works due to evaporative cooling. You really need to create an “atomized mist”, so most of the water mist evaporates BEFORE it hits the intercooler. Thus, the air going through the intercooler has been cooled by evaporative cooling. and will provide a greater temperature delta. Best to redo the set-up by having multiple misting sprays and point them forward INTO the air stream, in front of the intercooler..
This is like the OEM system for the top mount intercooler and the water wets the intercooler and vaporizers more slowly. over a longer time.
