P.O. had 215's installed does anyone know how that effects this truck? It seems to run high egt's 600*+ at 60mph flat ground MT & pulling a short 6% it will go over 1000*, probe is pre turbo.

 

What other mods do you have? Whats your max egt?

 

4" turbo back

 

600 at 60 mph on flat ground sounds normal to me. About 6-8 lbs of boost? Exceeding 1000 during a hill climb?? Big deal.

 

1-2 psi boost at 60 mph & 600* MT

 

I have a 215 pump and im hittin 800-1000 degrees flat ground at 100 km/hr (about 60 mi/hr), but im pretty sure ive got something wrong with my truck.

 

I believe my pump is still a stock 180.

 

does anyone have some stock 215 injectors they would be willing to sale or trade for 160 injectors

 

600 is running cold, if you ask me. Mine is almost always 1000+ on the highway. Of course I have more fueling and seldom run empty. If you're not constantly having to back off when loaded and climbing a hill to stay under 1350, I think you're fine.

1-2 psi seems low. I'd add a boost elbow or adjustable boost controller (regulator).

 

1-2 seems low to me too. seems like even without a load, my truck is always floating 8-12 PSI.

My egts are always 600 degrees when running down the road. It runs hotter than my old 24 valve egt wise. However i think these old 12 valves just like to run warm. I've rarely had to let out of it to keep temps under control. I pulled an 8k tractor home on a 2k trailer on the last "heavy load" and I don't recall having to let out of it to keep it cool.

 

New detroit at 80k# 6 mile of 6% 500* is all she showed last nite & no more than 25# boost.

 

I've got a low mileage set, if your interested send me a p.m. or email thekidfan@aol.com

 

Are you now talking about a Detroit Diesel engine?

If so, that really has no bearing on the temp of a modified Cummins- you know: "Apples and oranges...". If you're talking about a Detroit Locker in your truck, that also has extremely little or no effect on EGT's. If you're in Detroit right now...

 

Yep the new 15 liter motors run GOOOOOOOD . And don't go casting a spell on me I am not going east again !!!!!!!!!!

 

600* going down the highway is good, making good, efficient power and not working the motor too much. 1-2 psi of boost at those speeds seems about right, my truck did the same thing with stock turbo. And with little boost and those EGT's, your fuel economy is good too. 1000* is fine all day on a pull. 1250* and up for extended periods of times is where it will start to hinder longevity. A quick burst of 1500*+ is ok too, just don't hold it there.

If you're not happy with those results though, check for boost leaks and such. But remember, boost going in results in heat coming out. More boost=more fuel, it's the way it works.
