Diesel Dynamics, give up the goods!

[krabman]

Now that Diesel Dynamics has announced availability of the new 03 turbo and intake can you give us a brief rundown on the pertinent specs? Cmon, you can tell us...

 

[KLockliear]

What would you like to know? I don't think I can post pricing here... but it's on our website.

 

[krabman]

I saw the pricing. What I was wondering is exactly what it is? I read on the site that it was not an HX40. I believe it said it comes with a 4" downpipe, does that mean it has a 4" outlet? How does it drive? Is it weak on the bottom end for instance? Is it suitable for towing. Whatever other details you might want to pass on are welcome. I bounced around on your site for a while trying to find this info, perhaps you could post a link if I missed it? Thanks.

The air box is an open element box with an AFE filter. The box has the boss for the sensor and is completely powdercoated. We are also including a powdercoated tube to replace the silencer in the stock tubing to the turbo.



The turbo kit is a new turbo, uses a true 4" outlet and comes with the downpipe and clamp. It is also wastegated for the high 30's for boost. It is a more robust package than the HX-40 was, more durable and more efficient. We have 3 different compressor wheels we can put in it, as well as 2 different turbine housings, depending on the power application. The package also includes a new pipe from the turbo discharge to the intercooler, as well as the special piping to connect to our airbox kit. It will do away with the stock tubing.



It has the ability to keep EGT's in check completely while towing heavy (over 14k#) at the 400hp level.



We have also had Edge build us a custom level in our '03 True Torque Power Module that allows us to turn the power off, to control EGT's when towing on a truck with injectors as well. Since the box gets it's power from the rail pressure sensor, if you just unplug the sensor connector, you lose the boost module function - we have gone around this by making a no-power level.



We have also found the fuel system to be marginal, and fuel pressure drops dramatically above 400rwhp. We are in the final stages of testing a pusher pump kit for this truck. Fuel pressure gauges are available as well.



Anything else I haven't addressed?

 

[krabman]

Thanks for the response. I have promised my wife I wouldnt reduce driveability of the truck since she is the one who backs the boat in. Talking to SBC it sounds like that is going to keep me in the 400 hp range. I would like the power throughout the rev range and full time, not just a setting on the box I can use for a few seconds to whoop a ford before the egts go through the roof. If I might inquire, how would you reccommend getting there?

Kevin,How do they respond H/O vs S/O?On calif. trucks do they still get the same power?

Krabman, check the configurator on our website. It was also updated just before 5pm on Friday, so it has the latest info. There are a few ways for power around that level, but it will give you all the options and costs.



Catoiler, regardless of their stock HP, they all respond the same... meaning a truck making 285hp (6-spd HO) will gain the same as a truck starting at 200hp (CA auto)... so the CA auto truck will still be at a deficit with the same mods.

 

[Mopar_Mudder]

About the fuel system being marginal. Their has been much discusion about what the 2003's need, some saying that the pressure isn't imoprtant as long as their is flow to the injector pump. Has anything been determined about this?

 

[KLockliear]

In our testing, over 400hp will drop FP below 6psi, and misfiring can occur. For these applications, we are working on a fuel system kit to raise the inlet pressure back up.



We currently have a kit working up to 500hp, but that's about it's limit. We are continuing to source parts and try different configurations to get the pressure up to offer one kit that will support higher HP levels.

 

[Mopar_Mudder]

Interesting, I remeber seeing post where the pressure on stock trucks would drop down to the 6psi area, and with the Edge EZ they would drop to close "0", but it was not a problem as long as their was still flow of fuel to the inlet of the injector pump.

 

[KLockliear]

With injectors, that changes a lot. Fuel pressure is an issue at anything over 400hp. You can't get 400hp with just rail pressure. The timing box is yet to be released, but I would imagine they will have the same problem at the same HP levels.

 

[krabman]

Oh yea, I was all over that as soon as I saw your site had been updated. What I mean is given my objective of 400 ponies I might be able to see that without injecters and just the turbo and one of the new boxes that will be hitting shortly. Or on the other hand I could come pretty much into the ballpark with just the DD3s and the turbo. Or is it better to get say the DD2s, turbo, and run a box on a mild setting to take advantage of the timing changes? What gets me the widest, lag free, no egt worries powerband? Thanks.

 

[KLockliear]

The Stage 3's with the airbox and turbo make right at 400hp on our HO truck. It runs sweet like that, and can tow 15k# with no EGT issues. You need a boost module with the injectors though. For right around 400hp, maybe a set of Stage 1's with the TTPM would be the way to go. That setup should give around 400-410rwhp.



I don't know what effect the timing/pulsewidth box is gonna have, as I haven't tested one yet.

 

[krabman]

With everyone seemingly having their boxes out shortly I figured you would already have testing ongoing. I guess there are still a few pieces of the puzzle to hash out yet. Sigh... Thanks for the info.

 

[KLockliear]

I don't believe the pulse width/timing box is close enough to be testing at this point.

Fuel MIleage

Mr Klockliear, What your doing is appreciated by many in our game, also there are many of us that drive 4X4 Automatics, We would like to see some Fuel Mileage for our Trucks... Since Dodge has screwed with the Timing and caused our Mileage to decrease I was wondering if your Company or any other company could come up with a way to help us Poor souls out here?? Is there any one interested in this as i am??? Please tell Mr KLOCKLIEAR what your Feelings are... Thank You Bill. . Oo. Oo.

 

[jimnance]

HP and Torque first, but improved mileage would be good too. I'm sure that Dodge/Cummins has the fuel timing set to improve emissions and may not be optimum for fuel economy.



For sure, the annoying delay in engine RPM reduction between shifts is to improve emissions.



I'm waiting for a fuel pressure AND timing box before I spend my dollars.



According to Edge their timing/fueling box won't be available for another four months. Current owners of the current fueling boxes will be offered an option to upgrade later at an undetermined cost because the current unit cannot be reprogrammed.

 

[KLockliear]

Radar Doctor... lots of people are interested in mileage gains... lucky for us, they go hand in hand with upgrade - call it a nice, side effect.



Our truck is getting around 20mpg around town with Lawrence driving it like a mad man (his normal driving). You know, power slides out of every corner, 110+ up the hills, etc.



Jimnance, FYI, that annoying RPM delay goes away with our turbo on the 03 truck. Also, I would GUESS, looking at the past, that Edge may first offer a timing/fueling box that does not offer rail pressure (much like the EZ/Power Edge combo that came out prior to the Comp the last time around). So you will probably be able to stack those two to get the same gains as the inevitable Comp version.

Without giving out trade secrets as to the brand and model of the turbo, can you compare it to other turbos we are familiar with? If it's a step above a HX40 is is kind of like a HX50? Is the housing a 16, 17, 18 cm? You get the idea. What is it about this turbo that makes it so much bette rthan say a PDR HX40?

 

[KLockliear]

It's just an all around better turbo than the HX40. The bearing package is better, the shaft is more robust. It spools better than a HX40, yet provides at least as much airflow. It works great on the 03 truck from 300 to 500hp.



We will probably eventually phase out the HX40 altogether in favor of this new one.
