Engine/Transmission (1998.5 - 2002) dd3's too much egt???

[zstroken]

I am debating on getting some dd3's for my 01 eth, my question is will the egt's be thru the roof? Or would i be better off going with 1's and turning the PE comp up to level 5!! Would i even be able to play around town empty with the 3's and level 5?? I have an AFE mega canon, and will be upgrading to a 4 inch exhaust. I know the clutch will be toast if i romp it, but that is in the future.

Thanks for the info

Go for the DD3s

If you're going to mess around in town with DD3's and Comp on 5x5, you'll want to upgrade the turbo, exhaust, and intake. You'll be looking at 1600* at a blink of an eye. If you're going to be doing any towing 8K lbs or more, I'd consider getting the DD2's.



IMHO.

I Agree With Charles

DD3's and the PE Comp set at 5/5 are a whole lot of fun for a few seconds, but the EGT's go through the roof. I wanted to be able to take any grade hauling my Lance Camper, but I didn't want the truck to smoke. Solution - DD3's and the PE Comp set at 2/1. EGT's around town and on the road are manageable. But it's nice to be able to have a "BLAST" once in a while too. But to keep the EGT's down, more is required such as what Charles suggested.

DD3's and a Comp on 5x5 will destroy your clutch. Romp on it once and it will slip. You would be well advised to upgrade your transmission, trubo, fuel system, air intake and exhaust prior to running the 3/comp combo. That is assuming that you have guages already. If you want to get the 3's I would unhook the pump wire on the comp so you would not even be tempted.

upgrade fuel system?

I already have an EGT, BOOST, and Fuel pressure guage. what exactly do you mean by upgrade the fuel system?? Pusher not be enough? I realize that 5/5 and the 3's would be way too much, but would I be able to tow 8k with the 3's on the 1/5 setting with my stock turbo? thanks for the help

I have a DD2's, Comp, B1 turbo, 4" exhaust and the AFE Canon and a 11K + trailer and I can get 1300 EGT's. easy on 1/5. I tried it on 2 through 5 and the EGT's would shoot up in the hills so I had to back it down to 1/5. I was thinking about DDIII's but I think I will stay where I am at until I can control my temps better.

afe mega cannon

how do you like the mega canon??

 

[BatMan01]

zstroken

The MegaCanon is a pretty nice setup. Installation was a snap and the filter flows great. I am still playing around with my EGT's so I do now know if this setup is going to give me the temp drops I need to use the Comp above 1/5.

 

[JR2]

A pusher pump would do fine, but I would also look at new banjo bolts that are drilled. Genos garage has them and so does wildcat diesel. I might also address that crapy little connection between the stock lift pump and the fuel filter. . that line is tiny when compared to the rest of the stock system. There are vendors that offer complete replacments for the stock lines and such... .

How about running DD3's without a box, does that work well or is a box needed to de-fuel?

 

[JR2]

Go here are take a look at what DD reccomends to add the DD3 injectors:

www.dieseldynamics.com/dodgekits.htm



If you want to run DD3's with an otherwise stock truck I think you need to add at least a boost module to fool the computer and not cause it to defuel as well as adjusting the wastegate or disabling it to let you get more boost. If you have the small HY turbo (2001-2 auto transmission) you will probably need a new turbo. You will also need to take care of the transmission as DD3's and a boost module add about 100 HP and that is going to toast either the clutch or torque converter (what ever you have).



I think this disclaimer on DD's website says it all:

Stage 3 to be used only for serious horsepower requirements. This is not for the faint of heart. You will see smoke during heavy acceleration at low boost levels.



All in all DD3's are a serious upgrade to a bone stock truck. Here is what I did before I put mine on:



Gauges

High Flow air filter

transmission upgrade (DTT TC/VB)

4" Exhaust

Replaced fuel lines and moved lift pump to rear

Edge EZ (acts as boost module and changes timing)

PDRHX35-12 turbo (had to replace the HY35-9)



With all those upgrades (about $4000 worth) I was ready to try the DD3's. The results are impressive. With the peddal to the floor my EGT runs about 1200 degress and my truck is flying. If I try to tow anything (like my 2000lb snowmachine tralier) I have to be real careful and watch my EGT. If you want to tow with this setup you would need an HX40 turbo minimum.



So should you run DD3's with out any other mods... NO. My reccomendation to the guys starting out is to get gauges and then get an Edge EZ or BD Plug-n-Play/VA. It adds a nice bit of Hp/TQ and is an easy item to sell later if you want to go bigger. There are places you can get an EZ for less than $500 if you look around.

Get the DD3s

I have DD3s a Hot PE Comp and 5" exhaust while towing a 16,000lb. 590 SuperL and pulling it on a 25' dual tandem Gooseneck weighing in @ 6250. That would be around 22,250lbs. I turn the box off when towing because the 3s are good enough alone. If I do run into EGT troubles I turn the Comp box to 1/1 or 1/2 which is fine for me. All of this is done with a BONE Stock HX-35 turbo

You probably don't have many EGT problems, but I think you need to list the other mods you have :



"HOT" Power Edge Competition

Diesel Dynamics DD3's

5" Diesel Pro exhaust

Mitchell Pulling Clutch

Head, Intake, and Exhaust Manifold Ported and Polished

Pusher Pump

Autometer Auto Lite Boost, and Pyro Pillar Pod

K&N RE-0880



These guys are talking about putting DD3's on a stock truck.

 

[zstroken]

not exactly stock

The 3's would be for a 2001 eth with an AFE mega canon, power edge comp, 4 inch exhaust, and a new clutch.

 

[fj40charles]

Zstroken,



If you want to play with the comp on 5x5 and DD2 or DD3's, you should think about an PDR HX40 or B1 bomber turbo. I just see how you could stay in the throttle very long with a stock HX35 turbo and not peg the EGT gauge.

zstroken -

You could probably play with that set up. I would not want to see you tow anything heavy with it and I would plan on a new turbo sooner or later. I have basically the same set up and need a turbo. Looking at a B1 or HX40 now.

[zstroken]

thanks for the info

let me know if your wanting to dump thatPDR turbo for a new one

 

[WadePatton]

I saw DD3's + fooler slapped into a stock- with gauges and BHAF- 01 auto yesterday at Tom's shop (you know who you are ).



He loves it empty, but is going to tow with it. I suspect he'll find bigger EGT numbers than are comfy under load. I also suspect he'll pop in a bigger turbo soon, maybe even a transmission. We'll see.

 

[JTroiano]

I have the DD3's and the edge comp. It is great!! Oh ya and a new con FE clutch from SBC. When I tow my 2500 pound boat on a 85 degree day my EGT's are 1200* or less with the comp off. I want a new turbo but the money factor is a little low after the DD's and the clutch. I was wondering about what other trucks come with the HX40 and if the B1 is a new design or if it also came on some type of truck that I could maybe pick one up at a wrecking yard? The other ? is want is the highest boost I can run and not worry about the head gasket? This board is great but cost me a lot of money. Thanks guys.
