This is a crazy idea to channel some conditioned cold air from the cabin (foot blower) into the airbox reserve compartment.
Why the "foot blower"? This is the least used function of the a/c system. I don't use it, my wife don't use it, no one use it so why waste it?
Setting? Set the blower direction to the middle of "face" and "foot". Speed is controled by the blower fan speed, temperature controled by the thermostat knob.
The stock intake is still the main intake. Only a small amount of conditioned air from the cabin is blown into the reserve compartment of the airbox, accumulating there at low RPM speed, and surge out during acceleration. Air taken by the engine will be filled by the air seeping into the cabin through the tiny gabs and holes around the car (you think it's air tight don't you?).
How it goes? Well? If set at max blower speed, can hear a sharp whinning sound presumably from the corrugated hose. The sound is even sharper and louder in the airbox. With all four blower windows on the dashboard closed, I can hear my car singing with different tone at different RPM! Haha!
Without the filter element in the airbox, I can feel a constant stream of "cool breeze" flowing out from the reserve compartment. Quite strong, that i think strong enough to cool down the temperature of the intake charge. By 2 deg C? I have no idea, but i purposely put it before the ITC sensor so that any change in the temperature can be accurately measured.
Monitoring the engine smoothness, FC and performance. Should be useful for hot sunny day craw without worrying about the lifespan of the blower motor (as in another idea of my friend), or get suffocated in the cabin (some suggested to plug the engine intake on the firewall).
