Just wanna know what sort of exhaust temps people are seeing on their FD's?



Either external measurements on the dump pipe/ turbo or actual EGT's.



Thanks

What does your gauge read in Celcuis or Ferh?

Umm, it will read both.



I don't want to permanently install a guage, but just temporarily attach a thermocouple to see what sort of temps I'm getting and purely out of curiousity compare it to someone else's readings.



So it could be either C or F.

my EGT is located at the base of my turbo appx. 10 inches away from the engine.



When I had water injection and shifting at 9000 rpms, by the end of 4th gear, I would be at 920 celsius. When I heat wrapped my manifold, same shifting/gear, I would see 1000+ celsius with water injection. https://www.nopistons.com/forums/pub...1047683517.gif

Anyone know what stock level EGT's are?



What is considered conservative or safe?



What is considered high or on the edge?

keep it under 900 celsius.

I mounted mine at the base of the turbo.
