EGT Temp Guide (1 Viewer)

[pablosubo]

Hello again.
The idea of this post is to hace in a single place different EGT temp records and experience.
Before i went Turbo I spended several hours reading the forum.
And after i turbo´ed, i spend even more hours.
So, for thoes super freaks, for people who are considering to put a turbo... of just for anyone to consult, I think that this list it could be very usefull
The idea is not to discuss if the EGT you are getting are too high or too low, just to have many data son then each of us can compare, get an idea of what are le lowest values, the higest values and see if they fall more or less in the middle (if we can collect enough data, I might then make some nice graph!).

I recommend to copy & paste the following list of values so everyone has the same data recorded.
If anyone thinks I might be missin something, pls add it
Thanks and regards.
Pablo
