Intercooler spray blurb:
Intercoolers are only effective as means to control intake air temperatures when their
cores are significantly cooler than the charge air itself. Once the intercooler is
heatsoaked, little heat transfer takes place and engine output is inevitably reduced.
The USRT system automatically cools the core, increases intercooler efficiency, and
reduces charge air temperature. It thusly eliminates losses and often increases total
horsepower.
To not waste coolant while still being very effective, though, any intercooler spray
system needs to use an intelligent, adaptive-learning controller. The “SmartSpray”
controller monitors ambient air temperature, charge air temperature, and engine load. The
control module then interprets that data using a software algorithm. Single or multiple
fine mist water spray nozzles are activated automatically by the “SmartSpray” control
module.
Because the system only operates when it is really needed, water consumption is typically
reduced by up to 80 percent over manual control, while dramatically increasing cooling
performance. (Manual actuation is also available to produce a constant spray of water
upon demand. The sprayers will stay on continuously while the switch is held down.)
“SmartSpray” can be interfaced with any 12V water pump or can trigger nitrous or CO2
cryo coolers. It is supplied with the control module, temperature sensors, wiring looms
and installation documentation.

Sidebar:
The knock sensor is attached to the cylinder block. It senses engine knocking using a
piezoelectric element. A knocking vibration from the cylinder block is sensed as
vibrational pressure. This pressure is converted into a voltage signal and sent to the
computer, which will retard the timing to eliminate the knock. Higher intake air
temperatures make knock more likely to occur and at lower engine loads.
The intake air temperature sensor tells the computer the temperature of the incoming air.
Since cold air is denser than warm air, it needs more fuel to achieve the ideal air/fuel
ratio. To ensure that this occurs, the ECU will open the injectors for a longer period of
time (increase dutycycle). The result is increased power output. As intake air
temperatures rise, however, the ECU may be proactively signaled to pull ignition timing.
This substantially reduces power output while keeping the engine safe.
Thus, there is a constant adjustment to the engine’s operating conditions and a
compromise made between power output and longevity. Obviously, reducing intake air
temperatures is key to maintaining output as well as increasing it beyond stock levels.
