06 Boosts lvls

[hackengineering]

I wanted to check what i should be getting for boosts levels with stock turbo. Mine will reach around 32psi for a few seconds but drop down to 22psi and hold there. This is all when pulling in the mountains with constant pedal. I have been having some issues with high EGT's and it seems i should be able to hold higher boosts.

No programers or foolers installed. I heard these are not like the old mechanical waste gates so i do not know how you can adjust them.

Any suggestions, besides programers or downloaders?

 

[p-Bar]

should hold around 26-28 you may have a leak

 

[Wingate]

my 06 model will hit 34 for a second, then back up to 32 psi and hold there as long as I can keep enough load on it... . Sounds like you may have an issue. .

 

[SierraRam]

Mine spikes at 32psi and will hold 28 under heavy load. I do have the Smarty running on level 5 and under sustained heavy load I can hit 1500 degrees.

 

[TCDiesel]

Yes, you should be able to hit 32/34 and sustain 28/30. . their is a reason for it not holding the boost, I doubt a programmer or device will help, or it will only mask the problem.....

BD has an adjustable wastegate kit; if there were no other problems identified, what could this increase his boost to?

 

[hackengineering]

Thanks for the responces, I cleaned the air cleaner and was able to remove the hoses from the intake to the intercooler. Cleaning and making sure everything was tight on those seemed to help i am now hitting 32psi and holding around 27-28psi. Are there seals i can replace that go between the intake manifold the air heater and air tube? Thats about the last place to look for an easy leak.

Yeah Todd i agree a programmer or such would just mask it and not trully fix anything. This is my first gen3 so i didn't know what the wastegate was like on these.

 

[TCDiesel]

Yes, 2 steal gaskets sandwich between horn plenum, their robust, I would check the 4 bolts for tightness before replacing.

Sounds like you got it fixed.

The stock tuning will spike to 32 and drop to 28-30 under an empty load and 28-32 under full load, at sea-level. At elevation it runs the same, but analog gauges don't compensate for the elevation like the ECM does, so it registers lower boost.

I would say your working as advertised.

I never thought about the elevation, yeah i live near 9,500' and each direction is a pass to get out of here. I will just keep an eye on it and hopefully this will help get my EGT's down.

Thanks for all the advise.

 

[AH64ID]

Be advised that if your running 60hp sticks and stock timing you are going to run HOT! At a minimum I would get a boost fooler!

Thanks for all the advise.

It may help but a boost fooler will help a lot more.

 

[DogramTD]

A bit confused... I thought smarty boost fooled... . but I run the same boost pressures as what TWest mentions. Should I be running a fooler? Sounds like the Smarty isnt doing much fooling.



Glad youre back on track hack!

Smarty does not boost fool, have said this many times. Smarty remaps the boosttables to allow more boost. Its option is to turn the WG cntroller off, if it works. It doesn't work on all trucks so a boost fooler is needed to clamp the signal from the MAP sensor. Once the fooler is added under heavy throttle the boost will hold at 35-40 psi and help wit the EGT's a lot, stock or modified. This is with the stock turbo and WG controller.

I Agree. When the Smarty is able to remap the ECM properly it will allow full fueling up to about 44 psi (max range readable by the MAP). A Boost fooler will allow levels to go above this.



If your running timing and low fueling (say 70ish hp) you won't see much over 33-35 psi, but on stock timing you would see 40ish with 70hp. Since I did my airflow improvements I haven't seen over 35psi on SW2.

get a smarty jr and set it on economy. this will lower your egt by about 200*. a camshaft change to get rid of the incylinder egr will lower it some more and a turbo back exhaust will further lower it.

Cerb,



I have asked this question before ( https://www.turbodieselregister.com...sions-2003-2007/222251-smarty-jr-cr-revo.html ) and you will see in the first response I was told the Smarty already boost fools, this is why I ask. Looks like I should look into getting a fooler.

While it doesn't boost fool, what it does has the same effect as boost fooling. I would say only 1% of trucks, or less, don't accept the way that Smarty allows for more boost than stock. So when someone tells you that Smarty boost fools, they are correct and incorrect. . You get more boost, but the Smarty doesn't "fool" the signal.

I know, and most of them don't listen and can't comprehend the difference either, no matter how many times I explain it. I gave up trying to even get the rudimetary principles across to some of those guys, they can't grok the diffs.



In no way does Smarty boost "fool", period. The concepts of remapping tables and clamping a signal so it doesn't exceed a preset point are totally different and have different effects, as you can see. They are done in different places and different ways, trying to compare them will just cause a whole lot of misunderstanding. :-laf



On a truck that doesn't have a WG controller the BF is not needed until you exceed 45 psi, but, on the electronic controllers if Smarty doesn't shut off the controller or you block the boost reference hose you get stock boost and a little more.



Buy a BF or just clamp the boost reference hose closed and problem solved.

So I am looking into a boost fooler; Quadzilla or BD? The quad is $25 cheaper, so I am wondering why such a price difference, is the BD better?
