Egt's How High Can You Go?

[Dbonzi]

I am contemplating sliding my stock plate forward now that I install a combo set of Westech gauges.

Its a 96 4X4 5SPD and still dragin the cat around.

What is the safe temp to stay below. If 1300 is safe is this safe for a small period of time or will it be a problem on a long hill pulling a large load?

Thanks for your input.

How high?

1300 deg F [with the pyrometer probe in the exhaust manifold] is considered the redline, don't know if I'd want to pull a long hill at 1300 deg F. I like to stay at 1250 deg F or lower when towing.



Lots of people exceed 1300 deg for short durations with no apparent problems. Been there done that

cool

I have this problem with my egt needle keeps pointing down on my 1500* isspro gauge. I have herd about some truck pullers that have broken 2000* and the engine didnt look bad on the inside. Just dont have it there for very long. Try to stay below 1300 if you are pullin a long hill.

I've had mine at 1200 degrees pulling a 13. 5K pound fifth wheel trailer into a 40 mph (or so) head wind across the desert from vegas to bakersfield. For about 2 hours in the open desert I was driving with the pyrometer and letting it drift between 1100 and 1300 degrees. Pulling at about 70mph and using about 1/4 pedal. You know what? I had 50K miles on the engine at that point and it finally broke in and quit using oil after that trip. You can't hardly hurt these engines unless. . Well I don't know how.

In the last year, my truck has been all over the chart performance wise.



When I pull, I try to keep it below 1250° F up hills.



In 'race mode', I've seen 1400° temps by 40 mph and still climbing fast. I may have touched 1600° a time or two.



I had some transmission trouble, and turned the truck down to help the new transmission get broken in properly. Lately, the truck will level off about 1250° F.



Last night, I removed my analog gauge and installed a SPA digital one. I went out on a test drive to make sure they worked. The first time I put my foot in it, the warning light went off and I recorded 1380°.



My old BANKS gauge has been reading 100-150° low for WHO KNOWS how long.



Gauge inaccuracies are something to consider.

Does anyone have a suggestion how to check for guage inaccuracies other then replacing. Even using the "replacement" method who is to say which is correct???



The reason I am asking this is because I too am getting some higher then I would like readings on long pulls and it was suggested that my thermocouple may be intermittent.

I have hit 1747 on the SPA Digital.



Towing is where I would be careful, playing around or dragracing will never hurt it.

I use 1350* as a good shutdown point. However,If you are not lugging the engine and have your RPMs up I have seen as high as 1500* to 1600* in larger Cummins and Cats.
