Car in sig is fully tuned, just installed an autometer EGT into the 3rd runner of the turbo manifold, about 1.5" from the head. The readings are as follows in F.

Idling = 950-1050

15 ingh cruise = 1250 - 1350

10 inhg cruise = 1400 - 1520

1-2-3-4 WOT = 1600 by the end of the run.

I have done as much research as I could, and find that these numbers are pretty high in comparison, but find usually that people are mounting their probe either in their collector, or just after the turbo, which has to be at least 100 deg difference right?

Any input is greatly appreciated!

 

i noticed mine was pegging 1600deg plenty of times in the past. no matter what i did to the fuel/timing maps the temps were the same. depending on how well your exhaust flows the temps may change a little if it's completely straight flowing but on turbo honda's the temps tend to run that hot normally. i don't use egt anymore for that reason...it seems to be a useless tuning tool. just don't hold it at 1600 for long periods of time and you will be fine.

 

Doesn't seem like the gauge is doing you much good if it's just pegging when you need it most. I would suggest at least moving it down the runner so you can tell if one day it is running hotter than usual.

 

usually anything >1800 is starting to get dangerous
