EGT gauges

[Roger Heflin]

Hello,

I am in the process of rebuilding an engine.  I am looking at putting
an EGT gauge on the new setup.   I would like a fairly easy way to
read all 8 cyliners and possibly log some of the data (maybe with
rpm).

So far I have found an aircraft gauge that will do all 8 cyliners, but
the cheap one won't log data and the cheap on costs $820 or so for all
8, which is a bit more than I really want to spend.   And this one
also has clamp on type probes, and from everything I have read the
weld on bungs with screw in probes leak less.   The aircraft gauge
will scan between all cyliners, and will highlight the highest
cylinder, and has high/low temp limits of 1100F/1650F which I have
been led to believe from others may be too high for a 11:1
compression NA auto engine.   Their is a more expensive aircraft gauge
that will allow the setting of the temp limits, and the cheaper gauge
will also alert you if there is more than a certain amount of temp
spread between the cyliners (settable at 95F or 195F).   I have also
been led to believe that the aircraft sensors are very reliable (long
lasting) but take a few seconds to get to reading a stable reading, so
may not be that good to use to look at a given point.

My other thought is to get a gauge that will read two at the same
time, and have two 4 way switches to switch between the cyliners, is
there any better gauge for this?
