Engine/Transmission (1998.5 - 2002) Jammer Injectors?

[Crankshaft]

Anyone running DD's Jammer injector? Are they the same as F1 Mach series? Just one really dumb question(or so) . Why does a stage 3 or mach 3 cost more than a stage 1 or mach 1?? All they do is cut a little bigger hole in them ,right? Does it cost that much more to turn up the dial on the laser? I can buy a 550 in lift cam for the same price as a 450 in lift cam. So why does a higher hp injector cost that much more? I think we're getting ripped off !!:-{}

 

[JR2]

All I can say is DD has never sold me anything I was unhappy with.



As for the cost... . you know the old saying. . you got to pay to play.

 

[Luke Warmwater]

Haha I have resisted saying anything about DD but what the hell good is a $190 big fuel line kit when they don't get rid if the factory banjo on the back side of the lift pump? One would think $190 would buy some nice anodized fittings and 2' of stainless line? Never again...

 

[Luke Warmwater]

I didn't ask a thing. I merely offered an opinion in response to the comment regarding DD never selling anything another individual was unhappy with. I was unhappy with DD and based on that experience would not purchase their jammer injectors.



PS to satisfy the on topic question... I like my mach2s.

 

[KLockliear]

So Luke, did you send the kit back for a refund?



Nevermind that that kit has been tested and proven to supply the fuel needed on 750rwhp trucks.

 

[Luke Warmwater]

We already had this talk. As you remember I told you once I had taken the stock line off and having also just installed my comp box with some help from a friend, I pretty much figured I had no choice other than to go ahead and install it since it was late. I didn't feel like crawling around putting the stock lines back on nor for that matter having to take time out of my day to go ship the kit back to you. I said it to you then... I expected a lot more from that kit for the $190 you ask for them. After a little further investigation it appeared that there other guys out there offering kits for less $$ with nicer components. Lesson learned.



PS Please explain to me how leaving the stock banjo on the rear of the LP does not for the most part negate any benefit that one my get from your kit, downstream? Wasn't one month after the install of comp and your kit that my LP died. People are free to come to their own conclusion. I just went ahead and made what improvements I thought I needed, to complete my fuel system right. I realize I'm just a stupid software engineer and certainly no diesel expert but I'm slowly starting to get a clue



Lastly, sorry for the thread hijack. I'll try not to do this anymore.

 

[Crankshaft]

Hey Kieth, Why is there such a big price difference between injector sizes? I could not find your jammers listed any where on your web site. Are they on there? And do TDR menbers get any discount on them?I am interested in a set of stage 2s jammers. Thanks

 

[KLockliear]

Luke, trust me, you are not the only guy out there to think that you need much more to support the HP. However, our testing has concluded otherwise. With just that line kit that you have/had, VP44 inlet pressure is usually up about 6psi on a 350hp truck from the stock lines.



With the addition of our pusher pump, which also does not change that fitting at the back of the stock lift pump, it will support over 600rwhp (#2 only). My personal truck runs those two kits exactly as we sell them - makes 511rwhp/1052tq and never gets less than 11psi at the inlet to the VP44.



Bottom line is the kit does what it's intended to do. You are free to choose to use what parts you want, just like anyone else. If you would have sent the kit back, we would have refunded your money. You chose not to, now want to come on a public forum and say that it's this or that. SHOW me where it doesn't support 350hp with a good running stock lift pump with at least 6psi at the inlet to the VP44. That's what it's intended to do and that's what it does.



Crankshaft, the difference in the price of the different power levels of injectors stems from a few things. First, each power level takes time to develop (R&D). This time costs money. The more time we take to develop at power level, the more it's going to cost. Also, more supporting products (turbo's, fuel line kits, etc) are usually required as the HP goes up to. Again, more R&D costs. For the actual injector, it comes back to time. Once we have determined that a given modification yields a given HP increase, typically, the more power we try to extract takes longer to "machine" or "run".



The Jammer's are not listed on the website. Their pricing structure follows the same as the True Torque II injectors listed. You just have to ask for them when you order. There is no TDR discount on them.

No, to be specific I said I was not happy with the value of the kit. You obviously don't see it that way. Regardless of what you say I don't believe a "big fuel line kit" that does not replace the most upstream restriction in the system, the banjo on the input side of the LP, is very well engineered system. I never saw less than 6psi pre-VP right up until the day the LP died. Coincidence? Maybe, but pulling fuel from the tank through a restrictive banjo I believe played a role in a two year old LP failing one month after comp install. Simple logic suggests that if the kit is truly designed to remove restrictions in the fuel system then replacing the first restriction in the system would be necessary to achieve the desired results. Like I said, people can form their own conclusions. If you still want to debate this that is fine, I'll start a new thread dedicated to the merits of DD big fuel line kit. Otherwise I'm done!

back to the original question



i love my jammer 4's



the perfect injector for me

 

[RussW1911]

Jammer II's

I put my stage II's in 3 days ago and haven't quit smilin' since. Not the biggest injectors by anymeans but they sure woke up my 6 speed. Coupled with the COMP..... now about that clutch!

 

[CumminsTex]

I'm saving for some jammers. As far as the oversize fuel line kit goes... . I just bought a F. A. S. S. pump. It was nowhere near $190, more like $390 but it came with the big fuel line and tapped straight into the fuel filter housing, no banjos. Then I went to ebay and found a Cummins banjo bolt that has larger holes than stock... Tapped that straight into the VP and have 22psi fuel pressure at the VP all the time..... I love it!

 

[Billywj]

i have a set of jammer 5s and they are great

Jammer 3s here

 

[rkdblacksmoke]

I have Jammer 3's and i think thier great, I drive around with the box off most the time and its plenty of power.

 

[BBliss]

isn't the jammer name tied to the edge products line of injector nozzles?

Yes - the tips are Edge and several outlets sell the tips, or install them into bodies as injectors.



I've got Jammer 2's and love them. Went with injectors because I didn't want to hassle with testing them while my truck was down. Got them from City Diesel for under $350 delivered.

 

[Holysmokes]

Anyone ever have a weird Idile (kind od a lope)? Or while its not up to temp kind of "flutter at 1/2 pedal after putting big injectors in?

 

[DLausche]

Jammer 3's here and lots of smiles. They are the Edge Jammer nozzles. Were labeled "DD00300" on the box so I assume they are the same. I am quite happy with the performance and the price paid.

How big are they? You could need them to be balanced. Flow testing, and Extrude Honing can help. If they are really big, that is the way they will be.
