Also remember if you hit 1600 for a few seconds it's not going to melt anything down immediately. It's like sticking a horse shoe in a forge it doesn't melt immediately.

 

Thanks for all the advice! I can understand that 1600 for a few seconds is ok but pullin an enclosed trailer up a mountain pass we can see 1500 to 1600 for a few minutes! Guess if the turbo melts he has a good excuse to buy a bigger better one!!
Hopefully glowshift finds that the gauge is off!

Also we now have a quadzilla xzt 2 on the truck. So the boost will hit like 36 max. And the exhaust is totally straight thru... Still need an intake but we did cut out the airbox some... And it didn't get any lower egts than when it was stock and not really any higher egts. So yeah I hope the gauge is bad!!

 

I would seriously consider taking the shortcut on the intake route and putting a BHAF (Big Honking Air Filter) on it the cost is going to be between $25 and $100 for the filter, and engineering your own bracket to keep it from flopping around. That should help a bunch. The other alternate is I see that HTT (High Tech Turbo) makes a cool air intake for the common rail trucks. I think it's around $180. I hadn't read the entire post you just did earlier. It's pulling up to 1600 with a straight pipe? Is it the stock 3" pipe? Also I understand the long steep pulls in the mountains with heavy trailers, I had a 98 12v. That I had turned way up, and would run it up to 1500 with Autometer gauges and stay around there for pretty long pulls several minutes at a time like you're talking about and never saw any problems, and had never really even seen the manifold, or turbo bearing housing change colors or anything like that.

 

Yeah maybe well have to do the bhaf for now... When u do that on an 05 do u just take out the airbox or what? I have the bhaf on my 01.
And yes he was seeing 1600 with a straight pipe and no other mods. It is the stock pipe. But on the these trucks the stock pipe is 4" or maybe 3.75".

 

Well I'm not sure what the under the hood stuff looks like on an 05, but on my 97 I just unbolted the airbox, that seemed to give me plenty of space for the BHAF. Also if you have the Quadzilla on there from what I understand you should be able to get better boost especially with a bigger filter. I'm betting on the Gauge being fouled it seems a little extreme for it to be running that hot Stock with the straight pipe and at least some improved airflow with the Swiss cheese air box.

 

There's nothing wrong with the intake system on the later model trucks. The stock air filter is rated at 675cfm, plenty for over 500hp. The PSM mod will add flow into the box, but even that is probably unnecessary.

 

i dont think there is anything wrong besides not being told in the beginning you was pulling an enclosed trailer up a mountain pass in the beginning when the egt's will get high if it doesnt downshift and starts losing rpm's

 

Arizona: as I said in the first post the gauge will hit 1500(sometimes more) unloaded. That's on the With a load(enclosed trailer) mountains or flat it will peg the gauge at 1600! And the another odd thing is that the high temps aren't when your lugging it up a mountain pass necessarily... If u hit the thottle and make it shift out of overdrive it will get hotter and stay hotter till u let off...
Opposite my 01 if I'm lugging it uphill the egts will get high but if I kick the overdrive out they drop a couple hundred!

 

If the temps are even close to correct there WILL for sure be carnage soon and the head will have to come off to reveal burnt pistons.Please don't hold those temps over a mountain,if t's done it for very many miles the gauge is for sure wrong.
