Thought ya'll might find this interesting. Decided to get an answer straight from Cummins.



*****************



Summary: 06 Dodge EGT



Solution:

Thanks for your Email message.



Under full load, most Cummins engines produce exhaust temperatures in

the cylinder about 1300 degF or so, on the engine dynamometer. In the

Dodge Ram application, it is not likely the engine could be ran at 'full

load' operation in the chassis but if it could (or if overfueled), the

exhaust EGT ahead of the turbocharger should not exceed the 1100 to

1300 degF range. The exact temperature will vary on different applications

with different pyrometers and the location of the temperature probe.



The pyrometer measures exhaust temperature and the probe is usually

mounted about 2 to 6 inches from the turbo outlet (after the turbo) and in

that area the exhaust temperature under 'full load' conditions should

be in the 700 to 1000 degF range. The pyrometer probe could be installed

ahead of the turbo for maximum exhaust temperature out of the cylinders

(1100 to 1300 degF), however, if the probe ever fails, it goes directly

into the turbocharger and will likely cause a catastrophic failure of

the turbocharger, plus additional engine damage.



Operation and maintenance will determine which expected engine life.

Adding too much "heat" without letting the engine breathe or reject it at

lower RPM is called "lugging. " Engines with standard ratings and

operated in "severe duty" applications cannot expect to achieve more than

60% of the durability life-to-overhaul of engines that are run at more

modest output levels.



For the best fuel mileage, reliability and durability, Cummins engines

should be operated between peak torque and rated speed. Do not lug the

engine when running in that RPM range. What is "lugging"? Lugging the

engine is when, at cruising speed, the engine is accelerated and it will

not increase the vehicle speed. Also, lugging is operating the engine,

under full load, below peak torque rpm.



Cummins does not provide gauges for the Dodge application, however,

Turbo Diesel Register in Georgia does supply gauges for the Dodge. TDR is

an independently owned business and not affiliated with Cummins, Inc.

Turbo Diesel Register has a quarterly magazine and specializes in all

kinds of information about Dodge Turbo Diesel Ram trucks. It is a

separate organization and not part of Cummins, Inc.
 
Towing up here at high elevations, I can easily see 1400 degrees plus if I'm not careful. I try to use 1300 as a ceiling, but it's hard not to want to use the throttle that's left.

I pull an 11,500 (empty) lb. fifth wheel and saw 1350* this weekend. Had to let up. Was pulling 50 mph @ 2000 rpm. I'm stock.





Damn , I need gauges bad .

Can't trust a stock motor for safe egt's.

Advance your timing 2 degrees, should drop your EGT's 150 degrees :cool:
 
Try raising your RPMs, if I am above 2500, my EGTs go down, those numbers from Cummins may be at much higher RPM then 2000, it is better for the engine to run faster, the only downside it more fuel.

Pulling 12,000 lbs up a long grade ( 6 miles) - 29 lbs boost, 2800 RPM, EGT 1320.



I haven't tried it since advancing the timing.
 
My truck is stock, no gauges or anything. I don't care if it goes to 2000 degrees. WARRENTY! :-laf But really, if you are stock, why worry about it. Maybe the hpcr engines can take more heat, more durable internals? :confused:

Wish I could feel the same with regards to egts and warranties but , i would rather avoid the whole headache. Can you imagine having a blown engine and having to deal with all the BS that will follow. :-{}

When its all over , you are not going to have a new motor but a overhauled one . Gauges are cheap IMO.
 
Anyone ever heard of a pre-turbo pyrometer failing and causing catastrophic turbo failure? It's damned if you do, damned if you don't.
 
Great INFO!!!!!!!!!

Good reading apreciate the post. I probably will never see 13k lb trailer but love info on subjects like this. Keep it coming!!
