Default 8-10 rwhp?

Hey everyone, I read somewhere that if you move your intake air temp sensor to a cooler location it will give you up to 10 extra ponies at the wheels, has anyone tried this? if so where is the best place to mount it

Not sure, but it sounds like you are just tricking the PCM into thinking the motor is getting cooler denser air when it's not. If your IAT readings are lower the PCM will make timing/fuel adjustments for the "new" IAT temps. I doubt it would be enough to cause engine damage but you never know.

I recommend getting a custom 93 octane tune b/c you'll get better gains and if it's from a good tuner it'll be the safer way to go.

Or....maybe the dodge engineers overlooked something and what you're talking about could be a nice cheap trick we can all take advantage of! Anyone else have some thoughts?

I seriously doubt it adds that kind of power. When I added my BFI intake I also ordered the iat extension wire which allowed me to relocate the sensor to the inside of my Airram Jet stream scoop. So I know it is getting the incoming outside air temp and not the under hood temp. I also used to run the aforementioned power wire and could not tell much of a difference with it either. My next mod to really be able to feel a power increase is to get a cam and dyno tune.

The computer needs ACCURATE readings from the sensors to provide appropriate air/fuel ratios. You could put that sensor in an ice box, and it would read cold, but the computer would dump alot more fuel to compensate, and you would get a rich fuel mixture, this won't help power. I always thought this thing was a scam... besides, you would want to lean the mixture to make more power, not richen it...

You're better off to actually cool your engine with a Jet 180º T-Stat than to try and "fool" the computer with a false cool reading.
...and If you want real control of your A/F to maximize performance, get a CMR Tune.

sort of reminds me off a trick we used to do long ago

we hung desert water bags in front of our radiators, those bags don't seal completely up, so they drip water constantly.
It changes the atmosphere in the engine compartment & there is a definite power increase
it is like driving in a misty rain, without the roads being wet
it worked real good on vehicles before all the computers were put in them

hanging those bags on the front of the radiator originally was done to keep the water chilled

Desert water bags are effective because they effectively keep water cool and appetizing to drink, especially on a hot day in the dry desert. Water kept in canteens will be warm or hot, and definitely won't quench your thirst in the same way. Desert water bags consists of skins that evaporate and cold water to keep the inner body core cool.
