Skyrocketing EGT temps on a cold engine...gauge error?
It's about 55 degrees outside and my engine has about 1600 miles on it. I'm running on a part throttle break-in tune and never take it above 4000 RPMs. However, today I wasn't even close to that. I pulled out of the driveway, drove down a hill about 1/4 mile, then gently pulled away from a stop sign. The EGT warning light came on and temps skyrocketed to 2200 degrees. Shifting into higher gears did nothing. Eventually, things stabilized then climbed to over 1800 when I pulled into another driveway and was practically idling. I'm scared to drive it right now. What are the scenarios that would cause this kind of problem?

Re: Skyrocketing EGT temps on a cold engine...gauge error?
Which plugs are you using and what heat range?
Where's the EGT probe located?
When you're running lean, EGT gets super high. Anything over 1800 and you start to melt **** (which, of course, you already know).
your part throttle break-in "tune" is making things worse. Get into the car, creep it home, and start going over your "tuning" calibration for timing.
That's the best thing you can do right now. Don't Drive it anymore for any length of time.

I know that oil pressure will be higher when cold, but the needle seemed to swing towards 100psi pretty quickly at low RPMs. Maybe I'm paranoid, but it was right after I added a little bit of oil and the turbo seemed to spool up faster, even though I wasn't trying to boost. I think I need a psychiatrist to help me deal with my car issues, lol.

Re: Skyrocketing EGT temps on a cold engine...gauge error?
your timing can be way retarded which will cause the burn late like going out through the exhaust ports increasing egt. i would certainly get the tune checked and also look at the plugs to verify the conditions in the cylinder.
what oil viscosity do you run, and what are your bearing tolerances which can be influential.
ohh, and go to the back of the shrink line, ive been waiting to see him for 10 years hahah
