Subject:New pre-turbo EGT measurements.
From:Martin Jagersand
Date:Sun, 9 Jan 2000 17:24:02 -0500

I've relocated the EGT probe pre-turbo in my Diesel Westy.
Best place I found to put ir is from the under side in the
exhaus manifild so the the sensor sticks in slightly diagonally
into the turbo inlet.

One concern I had is that the probe takes up a fair bit of area.
The turbo inlet is about 40x40mm and the probe is 6mm diam and protrudes
30 mm in so it blocks about 10%. Any thoughts about this? I angled
 it with the flow a bit, but ideally I would like to withdraw it 10-20mm.
Any thoughts?

Some measurements on flat ground are:

Driving         Boost           EGT
Condition
-------------------------------------
Idle:           0 Bar           100C
20Mph           .2Bar           125-150C
40Mph           .4Bar           200C
60Mph           .7Bar           350C     <- Waste gate starts to open
80Mph           .8Bar           550C     <- Waste gate open

Next step will be to put the intercooler back in and repeat measurements.

Cheers,
Martin
