What is the normal egt for these 600's and what it the upper limit you should look out for?

 

I just install my EGT gauge this past weekend. I have the 325/610 with an auto. I was surprised how fast it got hot.

Seemed to jump right up to 800* - 900* without even trying that hard (level ground, fair amount of throttle). But then after that, even WOT, it took a little longer to get it up around 1250* - 1300* or so. Cruising around easy on the highway (about 70 - 75) it stayed right around 600 * - 700* or so.

This is a stock motor with only a Pro-Guard 7 air filter and a smooth torque tube into the turbo. Hits about 35 lbs of boost with WOT.

My egt probe is PRE-Turbo so numbers will be higher then POST- turbo.

They say anything after 1350* is bad. NOT to stay at those temps very long as things will start to melt.

 

grandblanc; Is your EGT probe pre- or post-turbo?

I just got mine installed, post-turbo, on Sat. And running around on Sunday, mine was reading between 400 and 600 degrees, just running around. If I stomped on it going up a hill, it would climb to about 800 degrees, but as soon as I backed out of it, it would drop back down to about 600 degrees.

I'm no expert, nor do I play one here on the forum, but I have heard that pre-turbo, the temps can get as high as about 1300 degrees, but you don't want to run it very long that high.

I am sure that others, with more experience will chime in with more information.

I've pegged my competition autometer pyro at 1,600 stock turbo going down the track at 460whp, truck still runs fine

You can push the limits as long as you realize they can push back.

 

Mine is pre-turbo. What type of boost pressures are you all getting as well?

 

Mark@ TST told me that the 600's are good up to 1450 deg. I too have seen 1600+ on mine which can be allright as long as you are not there long. you don't want sustained EGT's above 1450.
