I have heard that jim at DIY injectors said you can weld the split port on the barrel to convert the AD to a single and allow it to flow close to 160cc... Has anyone else ever heard of this?

Now, the reason I am posting is this. I have always read that an AD injector with a good tune. will max out at 140cc? With this being said that just shows how wastefull our split's are compared to a single. We are bypassing 20cc/1000 shots for each injector.


For my knowledge, does anyone know how far the travel or stroke of the AD injector on a max flow tune is? Using my calculations with a 6.00 diameter plunger and a travel distance of 5.6-5.7mm that works out to be very close to 160cc/1000 If so that means we are wasting the travel of .5-.6 MM every shot due to the split.

 

Hmmm... I had never heard that.....


What is it you weld???

HUGE picture, makes me side scroll, post a link instead, please.

I would guess that you would simply have to weld closed the little passage for the split shot pressure relief.

And I think it's a BRILLIANT idea!!!

I haven't forgotten about your PM, but so far I haven't come up with much. Check this link, this Joeservo seemed to know about the IDM and injectors, since his IDM mod strokes them for all their worth. If I stumble across anything else I'll let you know.

Injectors are very inductiove loads, turn on the injectors faster
7.5A initial and 3.5-4A hold 560uS vs 440uS 140V vs 110V

 

Yes i was thinking that all you did was weld the passage shut on the barrel and let the plunger the same since it would have no where to vent to.

 

I don't think that is possible but I have been wrong before.

 

I do not think it is impossible either, but, you will need single shot programming.

I for one love the sound of the single shots, and am replacing with singles when the time arrives. I will pay close attention to this thread. Maybe Bean's Diesel is a guy to contact with questions about this.

 

well i would think it is possible. Without a doubt it could be welded. the question would be the ability to weld with that much precision.

 

Might be easier to drill the passage larger about halfway down, kind of like a countersink hole for a screw, then fill that hole.
Just guessing here, never had an injector apart to know, but it would be a lot easier to drill down a bit, then fill that hole. And there would be all the welding spatter to clean off of the piece.
Welding is not that precision and it would be tough to get a good bead with that small of an area.
It might be more trouble than it's worth. I would definately not want to try it on a set of injectors that I could not afford to replace if I screwed it up.

 

ok so i have a question.it may be a little dumb but im new to the powerstroke world. do our trucks have the single or split shot injectors stock?cuz i thought they were single shots.i always heard single shots were better.

 

Our trucks have split shots for emissions purposes and noise reduction. They are not as good as single shots which have a higher flow potential and are somewhat noisier. All of this is my opinion.

 

I wasn't planning on trying it just wanted to toss the idea out to see if anyone else heard it, or has tried it.
