The .pdf shows they are EDM. Maybe they vary...

Great discussion!! If someone chooses to go with something bigger than 160/100's only to have them detuned for what they currently have... in my case I have a 38R, 4" exhaust, DP Tuner and HD4R100. What would I need in addition to that in order to run bigger injectors to their full potential? What would be the injector size limit if I didn't do any further mods other than a T500?

I would recommend head studs and pushrods/valve springs once you start going after HP. Also, i would check out your fuel pressure under full tilt.. might wanna upgrade to an Frx or RR fuel system

I don't like the idea of 80's being turned into 100's and causing issues. Although I still have many questions and much to learn, 238/200's or 160/80's is what I believe it's boiling down to from this thread's info.
Btw, the injectors will be brand new. Thanks for that help, Tugly.

I just had time to pop in on this right on cue. In deference to my esteemed colleague, 2000ca250, I need to add a caveat to what he says. Stock is a split-shot. AC is a single shot. If you take these two injectors and give them precisely the same PW, the AC will give more fuel and do it earlier (higher HP, lower EGTs).
- ACs "off the shelf" can be replaced from the shelf at an IH dealer if you ever need one injector... but the difference in wear will leave the engine unbalanced. I know what a fan you are of stock configurations, so this is the one to feed that urge. The AC stick is engineered for the HO T444E, the fraternal twin of the Powerstroke 7.3L. Somebody has already done their homework and it is a truely "safe" power bump... but you still have to change the tuning.
- AC 160/100 is the sweet spot for reaching for the permagrin while hangin' on for dear life to the DD reliability. That's why I chose them. By going new, this will help many miles down the road because custom nozzles put you in the "all or none" practice at replacement time. Replacing one or two sticks here and there just introduces imbalance in the engine... thereby increasing wear. And yes, they can be dialed way back to stock (or less)... but the idle will not be quite as quiet as stock. Not too loud, just different-sounding (like an OBS truck)

Thanks Tugly but I don't want ricers to think I'm mean nor do I want to waist my time embarrassing school children. I want to blow the big 6.7 that shamed me at a light the other day (while I was in 140), be able to do it with the bed fully loaded, back to the good ole days of the 7.3. And I still want to be able to do it with the same injectors 100k miles down the road.
I like the fact that the bigger nozzles can lower egt's, that's a technical tidbit of information I was as well unaware of, but the question now is what's the first number stand for in these injector numbers, the 160 or the 238 or 250..?? I know the second number is in direct relation of how much fuel the nozzle can flow compared to the stock nozzle, not certain the first number.
Please spare the noob. Thanks.

so 160cc, 238cc, 250cc, ect..
The second number is percentage over stock.. 30/60/100 ect ect.
Just be happy you got a ford.. cummins boys are all screwed up.. HP rating.. LPM, LPH, percentage over, gpm.. it's terrible

That 6.7 took three lengths to my every one off the light, both of us empty. Pitiful how slow my truck was, how slow she is. That was the day it hit me that I need to come of age.
The bed fully loaded was an exaggeration of my day dreaming. I know what all is involved with keeping up with Jone's, it'll happen just piece by piece.
I'm really leaning towards the 238/200's so that if and when I do purchase a 2000 model 7.3 than I can swap injectors and get the most potential power from them on that truck. I just hope they work properly in this one.

All I know is I want and must have brand new injectors, I can't take the risk at the moment of used giving me troubles. If what you say is true Stewart then what would you recommend now, knowing I must have new? What's the biggest I can get, the most "powerful" so to speak...?
