I just installed my egt sensor on my early 99 7.3 and was wondering what is a safe temp to run at. I have a edge evolution set to stage 2 and am running around 700 to 800 degrees. If I really get on it, the temp jumps up to around 1075 but just for a few seconds while the pedal is to the floor, and then it is right back down to around 750 as soon as I let off.
General rule of thumb for EGTs is sustained up to 1200-1250*, bursts can go above that, but not for long. Sustaining above that, depending on how high you go, can start melting stuff.
As long as you installed the sensor in the bend of the manifolds, you can sustain 1150 or 1200 degrees towing or open running with no issues. On the high end, if you are upwards of 1400 or more, you better not be there for a long period of time. I have hit 1500 once and got freakin scared. A few seconds ( less than 10 I'd say) on 1400 and I'd say that's enough, you'd better back out.
In the mountains here in NC, on the interstate crusing at 70 I see 700.
If the sensor is mounted post Turbo, then that's the wrong place.
I have not been able to try it out that much I just put in the egt sensor this morning and have only had it out a couple of times to try it. Most of my test driving today has consisted of putting the pedal to the floor ( I just installed my programmer ) so I need to drive it normal and see what the average is. And yes I installed the sensor in the driver side manifold just before the up pipe to the turbo.
what could cause the EGT temp to go up all of a sudden ? Was staying around 400 to 500 range all last week and now running in the 500 to 600 range. Running Edge Evolution with Silverline exhaust.
EBPV, possibly. Could be sticking or working, but not properly (like mine was). I unplugged mine and haven't looked back.
