Thank you Loren --- very interesting information.    I never dreamed
of owning my very own diesel Bunny--  in the days when I helped some
mechanics install pyrometers on an  E  boat.   It had 3     20 cylinder
aircraft diesels   ---60 probes  BIG gauge  and a selector switch.
So I missed my chance to learn exactly what was going on.

I have a lot of hands -on with egt's on gasoline jobs. There max fuel brings
the temperature down.And max lean destroy some engines. In this context
max lean is at the peak temperature.  On the lean side of peak in detrimental
due to heat.    Excess gasoline cools the engine.   Overfueling a diesel does not 
cool a diesel ?    I can't wait for summertime ,so I can put all this new learning to the
test. I am also going to use water ingestion like I had on a Ford V 8 flathead.
Yes I did try a "REAL"  water injection system -- do not recall where the water
was injected --- maybe just in front of supercharger.On a high power gasjob.

Hagar.
