Improving my dual mode MBC system

After toying with the solenoid control dual mode MBC system a few months ago and got it perfect. I am now adding the IC water spray system using STI OEM spray nozzles to the dual mode MBC system.

When all done I will have an on-demand water cooled boost system :D

The system will have the following parts:

STI OEM IC spray nozzle (see pic).
STI OEM IC spray on/off switch replacing the MBC switch (manual version).
Flojet run dry on-demand water pump.
Thermodisc adjustable temperature switch.
Grainger water level switch.
3-5 gallon tank in the trunk.

You can modify this system using a boost level switch instead of the temperature switch.

This will create an on-demand, controlled by IC temperature/boost level, shutdown when run dry system.





Nozzles can be purchased from at least the following site.

couldn't you tap the BOV line for boost monitoring and at a certain level, start up the IC spray. I think this is a great idea, I'd be very interested in seeing your setup (complete with pictures :D ) and would appreciate it. I think the Rally Cars and some STi monsters have fuel tank sizes containers full of water to spray on the IC.

Both STI and EVO have factory spray system build in. STI uses 2 nozzles and EVO uses 3 nozzles. I will be using a 5 gallon tank in the trunk so I can use it for long night out :D

As for using the boost level switch instead of the temperature level switch. I don't want to spray the IC when it is cold in the morning or during cold weather since it is a waste.

The system is on when I want to get max boost and I want the IC being chilled to extract all the HP I can get. The whole idea is to cool down the IC during idle at the light :) and during shifts.

The MRT system is the way to go if money is not a problem. I will post picture of the setup when it is completed :D
