EDM injectors

I am currious how these smoke compared to my DD3's on a hot day with the AC cranked and I nail it after sitting at a stop light.



I guess we will have to wait till summertime for that.

The ones I have will smoke more because of the hole size we went with. If you had a set of 100hp multihole EDM's they WILL smoke less then 100hp extrude honed injectors.



I'm keeping my DDIII's for next winter most likely, unless I decide to sell'em. I sold my BD IV's.

Regarding the smoke I was refering to... . I meant at 0 boost and give it some throttle... . my turbo is at 8psi or so before 1500rpm



Yes that's exactly where I see much less smoke with the EDM's than before. ( Same ECM software used)



BTW. My HX40 is already spooled up by 1400 Rpm. That's due to the combination ECM/EDM'ed injectors. Better combustion...

Oh, yeah, I must also say that the fuel here is much better than the Diesel you have in the States ( Higher cetane ) that helps also.

You're right Eric, the EDM's smoke less than extrude hohned injectors. I do not want to say that the EH injectors are not good,

fact is EDM is better.

Kat, would you say the EDM's smoke more or less than your Bully Dog IV's. . or do you need more time with them to make that judgement call.



I am looking for a possible substitute for a set of DD SM's

These make more hp then my BD IV's ... . and as of right now they smoke the same maybe slightly more?



I'll be able to tell more when it warms up around here and I can driv'em like I want to.



Also in this equation keep in mind I have a B1 turbo, a 93% torque converter.



Just quickly reread the thread and noticed I didn't mention the power level... ... ... . my injectors are around 140 to 150hp... they made a 145hp in the truck they were dynoed in in TX.

Hope you like'em. Not sure how cold you get but let us know how cold they start up without being plugged in. Also I am curious as to how you think they drive when its below 10° out. Like I stated in my truck you have to be light on the throttle.

I dont think it has been below 20* here this winter. It has only snowed here in town 3 or 4 times this year and has been gone in a day or two. Rain now that is another story. I bet it has rained more in the last month then it has in the previous 4 months. My altitude is 2660ft and that is why I get the smoke. My BD3's smoke pretty good even at 30*. I can even get my DD2's to smoke at that temp.

As far as nozzle breakage goes, why would you consider Don liable? Do you hold injector vendors liable if you melt a piston due to high EGTs? Do you hold a transmission vendor liable if you have an exhaust brake and fry the torque convertor? No I don't hold Don liable if it were to happen, however I'm not worried about it happening I know whats been done to prevent it. If someone is afraid of it happening then don't runn'em... . problem solved.

Tip Breakage and high EGTs are two different animals all together. If I bought a new set of DD or BD injectors, installed them, and they broke a tip off 1000 miles later, you better believe I'd be complaining. Not saying there's going to be a problem though.

Ok and if it breaks off 50,000 miles later..... still liable? 100,000?



Sorry but theres risks in everything we add to our trucks some more extreme then others, if you don't wanna pay then don't play! (not directed specifically at you banshee. . just in general). I have no doubts about nozzle fatigue and or breakage with these injectors.

 

[JR2]

So I guess I will ask the $$ question, how much $$ are these new injectors running...



You can PM me if you don't want to post the info.

Correct me if I'm wrong, but doesn't DD warranty their injectors for 100,000 miles again defects such as these? I know there are guys who have several hundred thousand miles on aftermarket injectors, but who can say the same about EDMs? No one can. I'm just saying that if I pad a grand (or whatever they cost) for EDMs and they broke shorty after (wiping out pistons and valves and who knows what else), then yes, I'd be hot. I agree a lot of this is a risk, but all I'm gonna say is, Better you than me.

In talking to Don, tip breakage was in his concerns and he spent alot of time researching of ways to address this issue. Right now there is no way to convince anyone this. So in time it will show that it will work,and hopefully those running them will be having fun with them during this time

Prices range from 1000 on up.

JR2, I sent you a PM.

Once these things get on the market, people are going to realize how good they really are and I think we will be seeing quite a few good posts on Don's injectors. I am of course speaking from first hand experience. No word of mouth. I have run several different combinations of Don's injectors and the power comes on quite a bit faster than the DD injectors. The smoke is there but not near as much as one would expect with the amount of fuel that they flow. It is very contollable with your box.

Mike your too quiet through this, sounds like I have my hands full with you, I told Don that I have to come down to Dallas Feb 19-21, I'll be staying over by love field so I may run up to Lewisville and try to get a run in, I'll get in touch with Don before I go down as I told him I would.



Take Care, Jim

 

[777 MECHANIC]

Jim, Looks like thats a Wed. Thur. Fri. I will be working, but Im sure Don will meet you up there at Speedworks. Im letting Don give most of the info about his injectors. Dont want to step on any toes. Im just the grunt and wrench man. I know he cant post here anymore but he does post on www.dodge-diesel.org

Don sent me a set of mach 3's today and I took them for a test drive. Prior to these I had DD2's in my truck. The whole time I ran with the box off and first impressions are that they have about the same hp as DD2's and the comp box on level 3. I had a hard time keeping the smoke down with them but I need a better air filter than the BHAF. My elevation (2800ft) also makes for more smoke. Tomorrow I'm going to try and run with the box on 1-1 to control the smoke and some all out blast on 5-5. I'm also going to try and dyno this week to get an idea of the hp increase over the DD2's. BTW I hit 44psi of boost with just the injectors before it settled down to 38psi (about the same as my last dyno run with the box on 5-5). The DD2's would only get me to 31-32psi.

 

[Boost]

I was hoping someone else would ask this question so I would not have to look stupid but... ... what are EDM injectors and how are they different from extrude honed? I was thinking of going up to dd3's but these sound interesting.

EDM== electrical discharge machining. The process adds more holes instead of enlarging the existing holes like extrude honing.



Boost, check out the link I posted at the beginning of this thread. Don compares his 100 horse injector to a competitors stage 3 injector.

 

[azcummins]

I would like to contact Don, does anyone have his phone number?



Thanks

Well not sure if he wants his home or cell given out (1 vs the other) so here is his email : Don M
