they are all a rip off!!!

 

Ya, I cant say I have heard a bad thing about either. I can tell you we sell more Industrial than any other if that helps.

 

i loved my jammers. had no problems. except after 80 when one failed. dont mined i got them used too. just got dd injectors. i did get a drop (minor) in egts vs. the jammers. and the haze is less. but i have had them on for only a week so
we`ll see how it goes!

 

There testing consisted/consists of a lot of trial and error and dyno testing. The machine to properly test is about 100k.

 

You are talking about the machine to properly test fir the injector, correct? I don't belive they have that particular machine. As for flow testing, yes, they are flow tested before leaving. DDP's biggest selling point is that the nozzles are flow matched within 1%.

Honestly, I think we are splitting hairs here. Both DDP and II are extrude honed injector tips. Both are modified stock tips that are hones out to flow more fuel. The only major differences I can think of between them is that DDP does their own injectors (I am pretty sure II sends thiers out), and DDP are flow matched within 1%. I don't know how balanced II's nozzles are.

I go through a ton of II pumps and turbos here, but typically use DDP for injectors. Not that I have anything against II, just that usually the DDP's are more competitively priced. Nice thing about the II injectors is they are injectors, not just nozzles. No assembly required.

Not sure what your experiences were, (as a shop, definitly more then mine) but the DDP's I got were full injectors. Pull out the old ones and drop in the new ones. Pretty simple swap.

 

Exactly.

 

well, i might as well add some more fuel for thought.

i've heard from a couple people that while it's important to flow test injectors you really don't want to buy or install any that haven't been pop tested because if they're off you can get yourself in some real trouble.

thoughts??

 

as for the tips compared to the full injectors. DDP only sells tips for the third gen engines the first and second gen injectors come as one piece. i'm not sure if II is the same way with the third gen injectors or not.

 

12v and 24v injectors are basically a pressure relief valve. The injection pump fires off a pulse of fuel. Once the fuel reaches a certian pressure, the injector opens and fuel flows through it. When the pressure drops below the snap, or pop pressure, the injector closes and fuel no longer flows. It is important that these types of injectors be pop tested in order to insure the injectors pop at the right pressure, and that the set pops at similar pressures accross the set.

The CR injectors are fired by electronic pulse. A firing device will assist in R&D, but for the most part as long as the injector is already working properly, it will continue to work properly after the nozzle is changed.

This is why MOST vendors sell complete 24v and 12v injectors. CR injectors aren't necessary. Now, lets talk about a guy with 2 bad injectors. Yes, the complete injector is a much better choice. However, the core charge on the injector assembly requires SERVICEABLE cores to be returned. If you have 2 bad injectors, you will be charged for 2 bad injectors.
