I live in a HOT climate 35 Degrees Celcius + in the Summer. Bad for Scooby's :-(((

I already have the MRT automatic water spray control unit working off air intake temps (above 40 Degrees Celcius), engine temperature (above 84 Degrees Celcius) and boost (above 7psi Boost). When all 3 parameters are met then the MRT unit triggers the sprayer for 8 seconds.

So far I am thinking of two upgrade options:

EASY OPTION: 1. Using a high capacity submersible pump in the windscreen wiper water tank feeding two extra irrigation nozzles with a manual switch and relay in the dash which I can toggle when I am feeling HOT ;-)))

HARD OPTION: 2. Increasing the size of the Boot tank, increasing the capacity of the standard pump and adding extra nozzles, whilst still being able to utilize the empty warning light.

Ideas PLEEEEEASE!!
