I have a gauge for just about every monitorable parameter, Just finished a 5k mile trip from florida to Minnesota to black hills and back to florida While towing my 11k TT through chattanooga, the highest my eot got was 240 going up the highest peak on I-24 but my ect was 204-216 depending, and eot average was 220, although going up I forgot to turn my a/c off.

My EGT's were averaging 1000-1200 I never gave it second thought as I was always under the impression 1300 was where you wanted to stay away from . After talking to several people including some forum members here that this was playing with fire and is too hot, I ordered a custom tune from gearhead and utilized the unlimited tow with powermax customization, it didn't help, it was still 1000-1200 I just tried to keep the rpms up to help cool the motor, I'm at a loss. Should I try 8k tow will that provide more boost to get more air flowing into the motor?

 

What do you have for exhaust?

Sent from my leash using IB AutoGroup

 

4" turbo back

 

Where is your EGT capture point? What oil do you run?

1200 is too high?

If you pull over and shut down it damn sure is...

 

1300f before turbo is the upper "safe" limit for sustained running. It's possible to burst past that for a short period, like a few seconds.

When having a conversation about EGT, make sure everyone is on the same page and talking pre-turbo or post-turbo. Post turbo will see 200-500 degrees less, so 1100f doesn't sound so bad post-turbo until one realizes that it might be 1300-1600 pre-turbo.

Bone stock it seems 1200 is the ceiling for temps from what I have seen. Put a tune on it and 1400 is easy to get just doing 0-60.

I placed the Egt probe pre-turbo on drivers side manifold, I run rotella t-6 5w-40 synthetic, FWIW the external BPD oil cooler was keeping up and kept the oil at a temp of 200-220. I have a turbo timer that will only shutoff the truck when egt's reach 400

 

T Think your EGT is more for Inject Prob then turbo

rare a Turbo burns down from heat
Lessover time is always a Bonus But

pre turbo you sound close
what did it run before

 

and is EGT same as other temps cold soak

 

I was under the same impression, but on a google search I was pointed to several threads one of which a responder made a valid point I cannot dispute. And that is if you research the melting point of aluminum, a quick google search says it melts at 1,221°F . So where does 1300 degree come from? That is what I have always gone as a general rule of thumb as well. As I understand it, if the Egt probe in the drivers manifold is seeing 1200, what are the valves and pistons seeing? That is my only concern. Thanks for the reply's. Just trying to make sure I'm not melting my motor.

 

I will check, it is a autometer 180 sweep pillar gauge, so you are thinking it may be reading off as in not starting at ambient temps? I do know it does cool off down to 300-400 at idle,

 

just something that needs ruled in or out

ID say say your fairly close not knowing the terrain in which it was tested or MPH
