Rebuilding a track-car I haven't used for 10 years, it has 2 VDO head temp gauges and was set up for #s 1 and 3. I'd like to be able to watch all four.
Has anybody ever set any thing up for this before? I'd like a switch to change from 1 & 3 to 2 & 4?
a lot of people have done it
check the air craft suppliers for the gauges like that
spruce is one...
but you probably would be better off monitoring EGT on each cylinder than 4x- headtemps.....
the EGT is going to be more money but more useful
I think a single CHT on #3 is adequate if you know your mixture and your EGT

Hey, appreciate it but what I was wondering was if there was a way to rig up a switch for an extra two sending units to use the gauges I have!
probably....
but why..
again CHT on #3 is going to tell you the whole story
and you can't use CHT to judge mixture
EGT will not only tell you mixture
but will give you real time info about what is going to happen to head temps before there is a problem
much better info
info available to prevent a problem
plus perfect mixture and max performance
not sure there is a benefit what so ever to adding 4 CHT readings.
I don't even run CHT on my race car at all
I use innovate wide band O2 for mixture
but in order to cut weight no CHT what so ever
