Btw, in case anyone is wondering the SCT software allows you to add or remove spark based on the IAT/ACT temp reading... so as air charge temp increases you can back off the advance a bit.
With the IAT/ACT located on the MAF, on a blown car, you have to make some assumptions about how much heat your blower will contribute to the air charge temp, and that change may be non-linear. You can actually vary the spark advance as a function of load, RPM, and IAT/ACT temp, so you could develop a pretty good table keeping the sensor located at the intake IF you had good specs on the temperature contribution of your blower at various load/rpm combinations. But it would still be easier and more accurate to just MEASURE the IAT/ACT measurement as it enters the engine.
Now all I have to do is figure out how to mount one of those things on my JR intake.
This company makes all kinds of temperature sensors, mounting hardware, and insulators for preventing heat soaking: http://www.tempco.com/Sensors/temp_sensing_hub.htm.
Note that all we need to do to adjust the voltage range is add a resistor so there is no need to buy a Ford sensor. Just need to figure out the current running through the stock sensor (which can be measured with a voltmeter at the MAF) and then take some readings of actal temperatures to calibrate the sensor. The resister value can then be selected to produce comparable voltage ranges in the sensor you buy. I am hopeful that I can slide one of these sensors into the small vacuum inlet hose opening in the JR intake that was previously used for the JR fuel management unit (which fuel management unit is now unused thanks to SCT).
