I'll be sure to keep you updated, I'm damn excited to see how my truck reacts. Once I get it figured out the head is coming off for some serious machine work, and I'm ditching all the twins piping in favor of a mid sized single and spray. Should be fun!

Bump. I'm still curious what % over stock flow those 6.7 injectors were that made 760hp.

im not sure im following? A 04.5 injector has narrower spray angle in a wider bowl. A '03 or a 6.7 has a wider spray angle in a narrower bowl. I will be putting a aftermarket forged piston in with a wide and shallow bowl similar to the 04.5. So it should not matter which injector i use, they should all spray in the bowl with out any issues? Am i correct? It will be a 6.7 bottom end with the injectors to be announced.

The issue isn't whether or not fuel is sprayed within the bowl confines - it's the direction of flow which determines the flame front's travel.
If your aftermarket pistons resemble 600 series 5.9L slugs (they have domes, right? ) you should use non re-entrant style injectors, as the early CR & 6.7L bowls are designed for a re-entrant pattern injector.
Yes, the engine will run if you mix spray & bowl angles.

All of the ones I have tried OHM out to the same resistance as 5.9 injectors even if the actuator is different the function is the same. They are without a doubt the cleanest performance injector I have seen. On the H2 vs. 181/210 comparison I used the 6.7l injectors on an '06 5.9l with an E.D. 66mm with an external gate. Fuel wise it had a smarty tnt-r, mp-8, and a bag of parts. It ended up making 760 I think after some tuning. And btw after the initial spoolup it was smoke free!

Well I've had a few headaches, did you use longer bolts for the 6.7 hold downs? Or just the factory ones?

Do not run these injectors until I figure out just why my motor melted down. It ran away on start up and now has no compression.

I'm not saying not to use them, I just wanted to put the warning out there until I get mine apart and can figure out what went wrong. I just don't want another guy to have the same kind of melt down I did. With that being said I'm pretty convinced it was a turbo blow out and has nothing to do with the injectors.
Zach, have you ever put a 6.7 head on a 5.9 block?

Would the 6.7 head be worth the trouble to swap, or am I better off porting the stocker? I think I am staying around 700hp.

Any news on the cause of the meltdown?

I can tell you already what happened......
The hold downs for the injectors bottom out under the bolts and need to be machined down for clearance.
The injectors were not held down properly, and in that case backflow fuel from the injectors could get past the copper washers and there's your runaway.
The engine stopped once the backflow was burned up.
So you can thank the one who told you you don't need to clearance those hold downs.........

To add salt to the wound pretty sure its not going to fire those injectors anyways....
I swapped one in tonight (along with modifying the hold down) and NO JOY.
I think Zack's full of chit, the current profile of the CRIN3's has to be quite a bit higher.

There was alot of fuel sitting in the bowls, alot. We're still really confused but I'll keep you up dated.

Can you give us a close up of how far the nozzle sticks through the head?
