[Fot] TR-4 EGT ?

[Jim Norlin]

I put them in 1 and 4 on the Spit. Worked fine on the chassis dyno where 
they have fans blowing all over the place to keep stuff cool.  On the 
track, the 1 reads 150-200 degrees colder than 4 because of the airflow 
through the radiator and under the hood, etc making the results useless 
for making adjustments.  I'd suggest 2 & 3, but haven't tried it. I took 
off the # 1 probe and am adding an o2 sensor instead. Haven't got that 
done yet either.
