More EGT reductions

[KevinO]

I have an 04. 5 auto with the TST donaldson straight thru muffler and AFE stage 1 intake. What else can i change or do to keep the EGT's from climbing so fast i nearly got beat by a chevy gasser yesterday cause the box started defueling. My muffler is 43" will a shorter one help. or am i just gonna have to buck up and buy a larger turbo? Thanks

Also on level 4 i'm only seeing 30 lbs of boost should i move the adjustable screw on the wastegate elbow to see more? and which way would it need to go.

I think that at 30lbs, that all the stocker is good for, right?



You better save up for that B1-03!! yeah!



Another idea, the F1-diesel EDM injectors are supossed to reduce egts too

My Diesel Dynamics Jammer turbo helps. The ATS manifold helps keep temperatures uniform in all 6. More boost pressure will just mean hotter air with the stock turbo.

KevinO,



Get the AFE torque tube, it helps flow more air and drops EGT's at a pretty low cost, it's not a truck saving change but helps overall. Customers call us back all the time with info on how it dropped their temps. The Stage II AFE is still no a for sure item so that's your best bet for now. The exhaust systesm can be improved on some to with a cat back system like our MBRP systems. Again it won't change the EGT world but will help drop it some, do you still have the cat in place? That's another place to look for EGT reductions.

I don't like cats :-laf so that is some help. i will try the torque tube since the stocker looks pretty restrictive with the baffles and such in it. yea tommy a b-1 is probably not too far behind. now just to have the transmission not care

That's not necessarily true, more boost pressure will not mean hotter air with stock turbo. Yes, more boost can increase the air temps some, but it depends on the efficiency of the turbo among other things. Its a trial and error test.

Odd, my 04. 5 with the Edge attitude goes up to 38-39 psi in a heart beat on levels 4 and 5, and I can't get it over 1100 degrees with the egts

I just talked with F1 today on the injectors for the 04. 5,... not ready yet. I've had my 04. 5 to 38 boost many times with no problem. And Tommygun, did you mean to say B1-04,. . I think.

Well, piers told me the B1-03 was a faster spool-up and VERY similair to the B1-04, so who knows what the difference is ???



I dont!

How cool!! See what ya learn on these sites. I don't recall ever reading anything on a B1-03. Sounds interesting and I'll have to check it out. Tks for the info.

Well I put on TST's wastegate setup on my '600', only as a precaution to avoid a turbo failure. Supposed to wastegate at 30 psi or so, but I have been unhappy since. Doesn't seem to have quite as much power so I would like to ruturn to the stock wastegate configuration which lets prussure build to 38-39 psi. More oxygen for combustion, and lowered egt's, should I do it? Anybody out there scrapped a '600' turbo yet?

 

[RAMINSPEED]

Methanol Injection! or Propane even?

 

[KevinO]

i'm thinking of cranking the adjustable boost elbow to pull a few more pounds should i screw it in or out? Also gonna try the stock air box and see what the difference is.

Screw in... makes the gap smaller, hence less air to the wastegate, and more boost

I just sold a customer a new turbo today he was running the tst box pm him about it lil red wagon and yes watermethanol or propane are good ways to cost effectively gain more power and lower egt's

BE VERY CAREFUL - this doesn't sound right at all - I think you may have a defective Gauge ---

Thanks guys i will try one at a time to see what helps best.

What is the best way to reduce my EGT's?. . while running on the extreme setting on my power pup ive seen my temps shoot past 1600 if I stay in it while in 6th gear... . I looked at my wastegate to see if there was something i could adjust to get a bit more boost (spikes at 30psi then settles to 25psi) but mine doesnt have any type of elbow with an adjustment screw... its just plain 180 degree fittings from the electronic solenoid to the wastegate head... I was thinking about trying to pinch the rubber line a bit to see if i could get a lil more boost... . Any help would be greatly appreciated

On my 04. 5, stock before the TST I was getting 36# and could hit 1200 Pre turbo. With TST installed, all else stock, I got 30# and reached 1550 once when first installed (setting on 4/4) The boost elbow screw was already tightened all the way - so I read on here how a couple people fiddled the little hole on the elbow to make it just a hair larger. - It worked great -got the boost back up to 36-40# on WOT and cooled a couple hundred degrees - by the way, my TST is without the guages and wastegate...



hope this helps!

It seems to me that as far as the wastegates on the 600's go... . the trucks with the 48re get mid 30's on boost from the factory and have the adjustable elbow... the trucks with 6spds get limited to 25-30 psi on boost and dont seem to have the adjustable elbow... . Im guessing the boost and hardware difference r due to the torque limiting on the autos... can any one confirm or deny my suspisions?. .

i don't have a gauge except for the TST but i couldn't see more than 30 on up to setting 6. No adjustable wastegate from the factory that i know of.
