Re: EGT thermistor location

   As the subject says, I am wondering where to locate the exhaust gas
   temperature thermistor on the TQC downpipe. My first idea was to
   place it directly behind the O2 sensor on the down pipe. Maybe 2
   inches back. Mounted at this location it would be sure to fit fine. But
   we began to wonder about the effect the O2 sensor head would have
   on the EGT sensor, as the O2 sensor would be infront of it and the EGT
   would be in its shadow so to speak. Something to consider or am I
   splitting hairs on a knats a**?

You want to locate the EGT probe as far upstream as you can get it.
Anywhere after the turbo, and all you're doing is guessing at what is
actually happening (the turbo will substantially [hundreds of degrees]
cool the exhaust stream, the actual amount depending on a lot of
variables that make it virtually impossible to "accurately" determine
the EGT.
