Engine/Transmission (1998.5 - 2002) Are my new mods suppose to be this loud??

[RacinDuallie]

Clmsnow,

I have the AFE with a stock turbo, huge turbo whine (over stock air housing), some like it, some don't! Most of us diesel heads can't get enough of it! I even open up just the passenger side windows to listen to the darn thing, and my exhaust of course! Have fun with your new setup!

LOL... . and I thought I was the only sicko!!:-laf :-laf

I'm very fortunate to have a girlfriend who loves my truck and all it's associated noises and smells, :-laf . I have to kick her out of the drivers seat sometimes!!

When I'm driving home to N. J. I go thru the Holland Tunnel from N. Y. C. - it's funny when I get into the tunnel and hold back some to get some distance between the cars in front of me-:-laf when there is plenty of distance and I get down on it and it spools up REAL LOUD- all the brake lights- light up in front of me- because a friend told me it sounds like a freakin jet coming up behind them!! And behind me- through the smoke- it sounds like a Big Rig on steriods... .....
and there is no other sound quite like it- and I have my windows down ready and waiting!!! Awesome- sweet music!! Can't get enough of it!

KWheaton. I was seeing over 40psi with my stock turbo and the guys here on the TDR told me I was asking for trouble with the stock turbo and my current set-up. I blew an intercooler line on a Sat, ordered the new turbo Monday. Egt's seems better on top, a little higher in mid range, but not dangerously high. I do agree, there is definately more lag and it seems much slower on the bottom, abd about the same in mid rnage. Top end, about the same but EGT's seem lower. I haven't really truned it up yet too much until I put my pusher pump on due to low FP.

RaccinDuallie. Here's another one for you. I put the Comp on 2x1 around town. It almost seems to spool up quicker and in the mid rnage with that setting compared to 3x5. What gives?? Am I over fueling causing more lag?

What -are you answering your own questions now?

I can tell I'm not needed here no more!!:-laf :-laf

Don't forget now your Comp settings will be different than what your used to with the stock turbo- this one you'll have to get the turbo out of the choke zone ( or Lag)
before that turbo can start to cool off the EGT's and you'll need to match the fuel delivery accordingly-with different settings on your Comp-

Must have one hell of a cloud workin before the sweet spot right?

 

[Clmsnow]

With the Comp on 3x5 there is a huge cloud of smoke. So what are you suggesting for the settings on the Comp box? Right now I have 1 and 2 at fuel level 1 and 3, 4, 5 at fuel level 5. How does the bigger turbo affect how I want to add fuel at different levels? As for answering my own questions... . ... I am still a young grasshopper

 

[RacinDuallie]

Grasshopper:-laf :-laf -

Think of why you have settings and sub-settings- What are you doing with the subsettings? Think now- I know you got it in you!! Again keep in mind where your turbo is choking or Lagging... ... . Do you want max fuel there ? Nooooooo- that's why there are those wonderful subsettings... ..... Like I said forget about your old settings- different turbo design now... whereas your old set-up spooled qwick and was able to use all the fuel earlier- the new one is bigger and needs more fuel after the choke point- following my drift here- I'm helping you figure it out on your own rather than just coming out with it... ... ...

 

[Clmsnow]

I see, I see... ... . I'll play with it at lunch.

 

[PC12Driver]

A different angle:



On a dyno, I get about 20hp more and achive peak torque about 100 rpm earlier running on sublevel 5 vs. sublevel 2 for a given power setting. And a bunch more smoke. So, you will build power more quickley on SL 5, but the SOTP perception may not agree.



On sub level 5 you get the max fueling from the Comp instantly, and then you get the extra push sensation and the smoke clears up when the turbo lights. On sub level 1 you don't get maximum fueling 'till 20psi of boost. So at about 1700-1800 rpm when the turbo lights off and whips through 20 psi, not only are you getting the push as the turbo lights, you're also getting a sharp increase in fueling from the Comp. So, you'll "feel" a bigger hit in the midrange on the lower sublevel settings when you're fueling hard when the turbo and the Comp wake up at close to the same time.

 

[RacinDuallie]

let him get that pusher pump on there before we talk about level 5... ... :-laf

 

[PC12Driver]

Whoops, good catch. I meant sub-levels (and I've edited my previous note accordingly).

 

[RacinDuallie]

Let's ensure that he has ample fuel to deliver first before we get him set on kill..... Oo. :-laf :-laf .

 

[Clmsnow]

I tried the different sub-levels... hard to tell yet. However, my FP is dropping down to 6 even on power level 3. Will the additonal fuel pressure from the pusher helps things at all? I also heard a strange(great another one) noise from the drivers side. Almost like a turbo bark, but on acceleration, rather then when letting off the pedal. The thing that confuses me is that if I added more air with the turbo, more air with the AFE AND 4" down pipe and exhaust... wouldn't I need more fuel to make it comparable to before? I called HTT and they said I may want to try a 12cm rather than 14cm housing if I can't get it right. Said it may raise EGT's a little.

 

[RacinDuallie]

Yes the additional fuel will help- stay low in the comp settings until the pusher is installed...

And they do bark or whoosh with moderate pedal application- it's almost like a surging feeling with that sound right?

Do not get a 12 housing or you won't like the EGT readings at higher rpm's



For now think pusher pump - Then we'll get you on kill mode 5



Patience- Grasshopper- you have the air, next is fuel- the equation will be power..... :-laf

 

[Clmsnow]

LOL... you crack me up!!!!... . but I am listening. Yeah, I think that sound is like you are describing. I may be putting the pump on tomorrow so I'll hold out until then.

 

[RacinDuallie]

Clmsnow,

Hey- Ya have to make learning FUN and interesting-no?

You'll learn over time-(I'm speaking to your right foot now- o. k. ? Clmsnow-just sit there and read a magazine or something while me and your right foot have this little chat here, thanks... ..... )

How ya doin' there foot? You'll learn over time how to control that barking turbo, you'll sense the spot where the turbo likes to bark and it's up to you foot to control this o. k. ? Sometimes it'll happen and your learned instinct will kick in-( pun intended ) so foot- when this happens you know what to do- I have the fullest faith in you foot... ... ... ..... :-laf :-laf !

O. k. Clmsnow I'm back to you again..... listen- relax when that little ol turbo barks like that- just let your foot do it's thang!

 

[Clmsnow]

LMAO!!! I just don't understand why my right foot weights so much more then my left. I may try to put the stock air box on tonight to see the difference in sound... I am still not convinced that I don't have an intercooler leak. Like I said, there are two very distinct sounds. Anyone know any good TDR members in the Sacramento area??

 

[RacinDuallie]

Why? Everything your describing here sounds just fine? These turbos sssssssssssssssssssssssssSSSSSSSSSSSSound like that. Take your runs with it and just keep eyes on your gauges they're your lifeline to your engine, after you put this pusher on I want to hear a full gauge reading report- got that?






:-laf :-laf And be nice to it til you get that pusher and some readings from your lifelines- I may just teach you how to make that turbo whistle DIXIE !!! That'd be different over there in Cali huh?

 

[Clmsnow]

There's no to much in Cali that is "different". There are all types of weird-o's running around. Luckily it's not too bad here in NoCal. I'll be nice to the truck until tomorrow night when the pump is on... then I'll give her h_ll!!!

Clmsnow,----After I got my Dodgzilla 35/40 the turbo whine was more than my wife or I could stand. I liked the AFE air filter because I had plenty of air flow. The ticket to quieten that turbo whine for me was the TAG II. You can still hear the turbo but it is much much quieter. Diesel Power Products, where I ordered the TAG II fitted the TAG to my turbo housing for a very reasonably price. This was necessary because my housing was not machined for the silencer ring. If your turbo compresser housing is already machined for the ring that part may not be necessary. Give them a call (509) 547-7029 Diesel Power Products in Pasco, WA
