Im stumped on the answer of why my 01 Dodge duallie is running high egt's. Maybe one of you can answer this puzzling question. I have a 5.9 Cummins with the following upgrades, 110 injectors, Banks high ram intake, ATS manifold, Fass electric fuel pump, HX35 turbo, 4" open exhuast w/ Banks 4' elbow, TST Power box, BHAF. The tansmission has been over hauled with a heavy hauler package Klevlar clutches and SunCoast convertor and shift kit.

The question is I can NOT get this dang truck to run cooler egt's and it has gotten worse !. I have made sure there is NO leaks from the turbo, manifold, and hoses. Someone is telling me to take the inter cooler out and give it to a radiator shop to see if the could clean it out. It is not visiblly clogged from what I can see, and Im not sure if that is possible. Im running out of options. Thanxs for any of your suggestions!!!

 

How much boost are you seein?

Have you made any upgrades to increase the boost?

Codes

 

I can only get 30-32 on boost on power level 7!!

 

thats about the most "useful" boost you'll get out of your stock turbo.

Any smoke?

Codes?

If no codes but smoke I'm guessin bigger turbo to supply the air to those big injectors you got.

 

How high of EGT's are you seeing?

 

My egts when I floor it and the boost starts rising so does the egts. I naturally back off the throttlre not to do any damage. I have seen for a quick moment going up hill with our gooseneck trailor loaded a egt temp at 1400, but then again I had to back the throttle off! I have another exact 01 duallie like this one with the only difference in the upgrades is that this one has a stock turbo, HX30 with a J-hook on it. It never gets hot.

 

How much smoke are you getting?

I'd be questioning the accuracy of the pyro??

 

Not much smoke, but I already replaced it from TST.

 

Ok today I poured a EDIT load of soapy water over the turbo to the intake and found a huge leak from the ATS 3 piece manifold where they meet. Would this account for high egts???

 

if your still getting 30-32 pounds of boost I don't think thats teh issue, seperate one though.

More boost out of that turbo and your gonna push hot air and raise EGT's?

I'm stumped. Sorry mang, only been here 6 months

 

According to ATS it could be my problem. They said they would call me Monday to see what they could do for me. Fingers are crossed on that issue!!!

 

Here is one of the pics of my ATS manifold that is leaking. This should make quite a difference in my egts, I assume, seeing that the exhaust gas temp are leaking out before they get to the turbo?? What do you guys think??

 

when the manifold heats up it probably doesn't leak there. i don't think that's your problem.

 

Again, what are you considering "high EGTs" to be? 1400 with your mods, loaded going up a hill, does not sound unreasonable. What are your cruising EGTs? How about a WOT run to 60mph?

 

I don't think 1400 is unreasonable for the mods listed. The manifold should seal up when heated, but if it didn't, you would see soot spray...and a lack of spool up and/or boost. 1400 is COOL compared to what I've seen for the past two years.
