[Vwdiesel] AHU Improvements

No, and yes.

The temp should go up, yes, but not that much.  The egt upper limit is
controlled by fuel injected quantity, not by adding combustively inert
material, so since the peak fuel injected quantity is not changed by the egr
deletion, the egt should not change either, and under real world conditions
may actually be lower due to the hot exhaust gas not being added, and cooler
air entering in it's place. This would not hold true for a gasser that had
to run at stoich all the time.  Yes, I realize there is an egt cooler, but
it doesn't cool that much, not like it's air to air or anything like that,
and as a bonus, you get no particulate carbon entering upstream of
combustion to foul things up.

I have a question, removing the EGR equipment could raise EGT, are the
valves strong enough to handle higher EGT?

Loren, my "new" machine shop discouraged me from putting Total Seal
rings in the 1.6NA for '82 Westfalia #2, they were worried about too
much compression.  What's your take?
