I have heard of people moving the air temp sensor from up by the throttle body down to the blackwing or whatever. Is there any real gains from doing this?

 

IAT re-location kit. Some people report gain, but I doubt it, IMHO

 

I don't think it's a power adder. However, saying that, mounted in the power bridge (aka 1997-2000), after you shut your car down, or during stop-and-go traffic, the IAT sensor will heat soak, as it sits right above the hot engine. It will take a while to cool down following these evolutions, as there's more mass to cool (sensor plus bridge). The engine rolls back timing during these periods of time. Now if you mount it in front of the power bridge, these effects should be able to be minimized. GM moved it in the 2001-2004 models (LS1 and LS6) and installed it as part of the MAF. Lingenfelter also moves it and installs it in the Blackwing flow meter hole, plugging the bridge hole. GM must have had a reason, and Linenfelter doesn't make many mistakes. I have drilled holes in my foglight shrouds and will ne moving my IAT sensor shortly. I have had timing rollbacks following a hot restart, and it lasts longer than you may think. As the Blackwing mounts far forward of the engine block, and doesn't see near the heat that above the engine does, especially with drilled foglights, I hope to minimize any heatsoak effects. This should get the car running at full power sooner by measuring actual inlet air temps, which, in my case anyway, will be mixed with outside air through the foglight shroud, and therefore, cooler. It can be embarassing demonstrating a car following a hot restart. This reasoning is JMHO.

Hey man , great info. I will probably move it for the heat reason then. Thanks a mill.

Is the wire long enough to move it down to the Blackwing ?

 

It wasn't but I can lengthen it.

 

which sensor are you guys talking bout?
is it the one that clips in the BRIDGE?

 

Yes thats it. It's in the front part of the bridge. Has two wires going in to the plug.

 

I might be doin this as well, great info!!!

 

I just got mine done a little bit ago. I haven't drove it yet so I'll see how it works tomarrow.

 

how do i do it if I have a VARARAM?
