For the water line, we got 5mm silicone hose from HPS Performance. We chose HPS because their hose comes in many sizes in 1mm increments and we wanted the largest size for the most waterflow.
We started by removing the bumper cover. Then we found the end of the orginal sprayer hose since we had been lazy and forgot to remove the entire system when we switched to frount mount.
We used this fitting to splice the OEM hose to the HPS hose.
The OEM hose was sitting by the firewall but we relocated it so it sat along the framerail toward the front of the car with the end on the frameral near the battery. We connected the hose to the HPS hose.

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
