[Vwdiesel] Egt for 1.6td

[lbaird119 at aol.com]

 Having seen the Isspro pre and post turbine gauges.  I believe it was 150F difference in the temps.  May have been 200 F but 150 sticks in my head.  The same gauges, just different location of the green, yellow and red bands.  Temp has to drop across the turbine since energy is being removed.

  I ran my Dasher at 1250F max boost.  Only ran it there for 20 seconds or so, at a time.  Otherwise I kept it to about 1150F.  I've had that engine apart a couple times (still currently is with a cracked head bolt hole) and nothing bad has  happened to it from heat.

It is variably inaccurate.  Just as a gas heats up with compression, the
eat decreases with decompression.  The gauge will be inaccurate based on
he pressure drop across the turbine.

 egt probe located at after turbo downpipe where it curves downward. Because
 of weight, 14 inch bus tires/wheels and wind resistance it can fly into red
 zone on the gauge so I am careful to slow down when that happens usually on
 long upgrades. I cruise about 55-60mph using and stay in green or yellow
 temp zone when on flat terrain. Sorry Im overseas now so cant say the exact
 temperature.  Im happy with the "smoke screw" adjustment. My question is
 how accurate is this gauge with the probe at the curved downpipe exhaust
 turbo location?
