Is the IAT worth HP?
It is known that colder air makes more power, but that's just half the story.
The intake aire temperature sensor (IAT) reads the temperature of the incoming air and sends the information back to the computer to advance/retard the timing. The warmer it is, the less advance the timing gets, and this prevents knocking/pining/detonation/etc.
However, chevy guys (ls1/ls6) can buy a resistor to plug into their IAT sensor, tricking the computer into thinking that the incoming air is colder than it actually is. This advances the timing a few degrees, and results in more power.
Of course the disadvantage is that you would have to run premium octane gas, as well as risk running into knocking problems.
Does anyone make/has anyone tried to advance their timing by installing a resistor into the IAT sensor?
Just a thought as i drive in 115 degree weather...
