New Power Module for 03 Dodge

[Tomeygun]

The Predator performance module is a really good choice , will make around 115 hp. On a stage III , and if you read the latest article ,in TDR its coming to light that fuel and boost boxes actually increase timing and duration.

I always try and stay out of the my box is better then their box argument . but with the latest articles in TDR on fuel boxes I thought I would expound on my ideals on diesel aftermarket performance .

Give Predator a call, the modules work great and the power gains are documented.

I don't question that the power gains are documented... But the website leaves a few questions to be answered

They will also tell you that a maximum EGT of 1350 degrees is acceptable, but IT IS NOT. At 1350 degrees metal glows red hot. Temperatures this hot can permanently damage your engine. Cummins recommends a maximum sustained EGT of no more than 1050 degrees. High exhaust gas temperatures also raise coolant temperatures, causing your engine to over heat even more. With the Dr. Performance! system, there is no need to add a pyrometer to monitor your exhaust gas temperature. Our system WILL NOT raise exhaust gas temperatures above acceptable limits - EVEN WHEN YOU USE THE EXTRA POWER - because we DO NOT add more fuel than your engine is already designed to burn!

That makes it sounds as if a stock truck and a Dr. Performance "chiped" truck will have the same EGT at any given time... Is that true?



I know many people with new stock trucks that can hit 1300* - But with this system, the EGT does not go over acceptable limits? Like I guess 1050* (per the website)



COMP - I'm not pok'in a stick at ya here, But do YOU think we should run without an EGT because it is not needed??? - You should have a talk with the Dr P web dude and see if it is the best idea to have that on the site...



PS - how much fuel was this engine "designed to burn"??? As much as COMP's truck ??

Tommy those injecter pics were very interesting thanks. makes one think a little differently about the boxes alrite.

So now we've all been "enlighted" with the injector issue(s). How many of us will remove our box's? How many will ignore it and continue to use 'em? And then the real question... . how many will see it as a darn good reason to upgrade our injectors!

Well, I only run on level 2 or lower now...



And what a great time to have them worked by DON... fixed and more HP, gotta love it!

I would run the Quadzilla box I have over 100 happy customers. Power is very smooth and egt's are managable.

yea, and there's a good argument to be made that the zilla commands lower rail pressures too. My opinion here, but I'm suspicous that the CAN bus technology allows it to make 100HP at rail pressures equivalent to traditional 60-80 HP pressure boxes. in other words, there's some pretty cool ("indirect") timing and duration stuff going on in there. This one was hard for me to place into my categorization scheme, but I'd call it "timing + pressure". its fundamentally a pressure box but adds timing and, via the CAN bus, coaxes a bit of duration out of the ECM that I expect tranditional pressure fooling might not acheive.



I'm also glad to see zilla refrain from quoting a maximum rail pressure figure, since that cannot be measured without specialized rail-modifying methods. The on board rail pressure sender (and all boxes that hook up to it) is blind to pressures above approximately 26,000 PSI. see TDR issue 48 for more detail

I have recorded 26200 with my VA on #3. One thing about the VA though is it defuels as the RPM's raise and load decreases. The fact that no VA boxes have reported injector damage may be due this.



Think of it this way. . at 3000 RPM other boxes are letting higher pressures through during each injection event and at such high RPM's that spray is is happening many more times per second where the VA has already defueld so the rapid injection events are done at a lower pressure.



The bummer is that you really feel the defuel when you run that high so passing is compromised in an auto that down shifts to passing gear. For safety sake i run my box off all the time unless I really need it so that probably helps too.

Well, I have never used higher than "3", but maybe better to go to "2" or "Stock"...
