Safe EGTs

[FordGirl514]

Hi! I finally installed my pyrometer. I was wondering what the safe EGTs are or the highest they can go without damage. I run Looney tunes extreme on my truck. Also, what temp do you think I should let them cool down to until I can shut off the truck?

Thanx

Im not tech, but from my own experience i've seen as high as 1200, and it usually stays at about 400-500 on the highway. i usually let my needle down to 200 before i turn it off...my not be right,just a habit.

You can go much higher (1400 or so) for very brief periods of time (like a few seconds), but keep it under 1200 sustained. Also, you don't need to worry about shut down temp unless you had a consistently long run with high EGT's. If you do, then you should wait until the temps drop down below 400 to turn it off. This prevents your hot turbo from vaporizing the thin layer of oil and seizing it.

Also my pyrometer reads 100º when the truck's shut off. Is that normal? Thanx for the replies

the lowest my pyro goes is 200. so it reads that when its off.

I have hit 1350 during a run but not for long periods. Normal is between 500 & 750. I usually turn the truck off at 300 because mine won't go any lower than about 275 idleing.

What kind of Pyrometer do you have? Some will just defualt at a set temp until they get a reading higher than that value.

I've hit 1550 for a very, very brief period and you might go this high also depending on what Looney you have. Like others have said, you should stay below 1200 if its for an extended period of time (I typically see 700-800 on the highway at 75 mph). Personally, I cool the truck down to 375-400 every time I shut down.

Thats seems to be norm..7-800 on highway...try to not substain 1200 very long...I hit 1550 when running a buddy the other day but that was at over 100..I ussually get around 800 till I grab the next one...hope this helps..

1250 max sustained. Shut down at 350 is what I do every time.
