That is simply not going to happen with proper tunes. I told Jody during live tuning that I did not want any smoke in the 80 economy tune and I have none of that no matter where I am in RPMs and throttle. Now the next two settings are a completely different story. I can blot out the sky if I roll into it way too quick.

So it is dependant on the tuning is my point. No matter the injectors or turbo. Sure big injectors and small turbos can be a challenge but they only inject what is commanded. Get a proper setup. Even big injectors can be pulled back to work with a smaller turbo but what is the point of that?

I go back to previous posts where I point out about efficiency maps and the ability to compute HP gains based on air and fuel flow based on the given turbo and the given never changing displacement of the 7.3. Is it dead on? No. But it is a pretty reliable tool that will enable you to calculate within 10 to 20 HP.

BTW, 160cc injectors are far from large even with 100% nozzles. What is the proposed flow of those, 160? Is that 100% of 160? I hate this injector % crap. Why don't they just post the flow rate?

160cc because that's the flow of stock AC injectors. I want AC's because they're consistent and are stock... they haven't been modified or anything. Reliability is basically it... between Clay and John Wood, both are saying AC's would make an awesome injector. About the nozzles... I meant 100% over stock nozzles. My fault for not clarifying. An AC is just shy of the flow of a stage-2... with nozzles, I'll have something almost as hot as a stage-2 and hopefully, I'll be closer to 400HP towing with this combo than I would with stock AC's. ALSO... I'm told AC's are bit better on Oil than other injectors. Just my thinking... that's what I'm going with.

ACs will put you in the 360ish range +/-. 400 simply requires more fuel.....

Right, but I don't wanna have to dump a ton of fuel in there to get that power... I know I can get 400-ish HP with stock AC's, but that's in the race tunes. I want to get 400-ish HP while in the tow tunes or at least pretty close. With nozzles and AC's, as far as I know, all that's changed is the nozzles, not the fueling. I figure that to equate to a bit less fuel usage than stock AC's and tuning... but what do I know? Just my thinking... not looking to get too technical, I just know that stage-2's are about where I'd like to be. I just want the consistency of AC's as well as the fact that they're unmodified other than the nozzles. If I'm right, the internals of the injectors are not touched when only changing out nozzles. Hope this makes sense... I'm not looking to see how much power I can make, I just want to be up there with the new trucks while at the same time being reliable and not pushing the truck so far as to be drastically jeopardizing the life of my motor. From what I can tell, 400HP seems to be that threshold between twisting it up safely and taking the chance of windowing the block.

If my goal was to have reliable 400HP while towing, one of the things on my list would be compound turbos.
You are going to need a lot more air than a single can deliver to be able to control EGT.

I don't know Dan. I think it can be done with a 38R, Modded H2E and there is RockRunner who is doing it with a ProCharger set-up from EmpireDiesel.

Send on some links!

I don't mind having to fix stuff... it goes with the territory. As they say, "You can't have your cake and eat it too." I'm just talking about "NOT-blowing-the-block-up" kinda reliable. I would love to check out a modded H2E... I hear it supposedly has the lowest boost to back pressure ratio. I also hear it's quieter, though... I may be weird, but I'd kinda like to hear the turbo. Could also be because I'm young...

I love the whistle on my 38R and my daughter loves to call me old.

I don't have an engineering degree, but my thought is this.
Ford's new design involved more than one turbo and they are pushing 400hp now.
For whatever reason, they felt that more than just a single turbo was necessary and one of Jonathan's requirements is reliability with that 400hp.
Just putting two things together in my mind.

True... the thing is, I don't have the skills or the knowledge to fab up something like, nor do I have the money to pay someone to do it, let alone buy the stuff to do it! I'm just trying to work with what's available... the AC's for starters, but I'm still trying to decide whether or not to go with a 38R of a modded H2E. Clay really thinks a 38R would do the trick... he's always been right so I see no reason to doubt him. Plus, an H2E is really expensive! I guess if I'm ever hard enough on my truck to go through more than one 38R, then I'd consider an H2E, but I highly doubt I'd be able to put my truck through the hell that CSIPSD does. I'm also still trying to figure out if I'm gonna go with a 1.0 or a 1.15 exhaust housing... some say the lag is pretty bad, but Roland says that he liked the overall performance of his truck after he got used to it. But hey, I've still got time and I don't have the money, so...

Dan, you have probably forgot more about the 7.3 than I have ever known so please don't take my previous post as ANY disrespect to your knowledge at all.

I am no expert to say the least. But there are guys running single turbos with hybrids that say they pull great.

*From my readings on 2 forums, I see truck owners and tuners really liking 238/80 and 238/100 hybrid sticks with good single chargers. Mainly the 38R and H2E. RockRunner is the only guy I "internet know" that is running the ProCharger and towing.

I was just about to ask about Hybrids... I know what they are and was even considering a set, but dang they're expensive. Plus, 500HP is farther than I wanna go... like I said, I don't wanna start dumping reliability because of my power and from what I can gather, 400HP seems to be the threshold. Plus, I'd rather go with a new set of injectors and AC's with nozzles installed would cost less than a new set of Hybrids.

For me, this thread Uniform Injectors Standards - PowerStrokeNation is like drinking knowledge from a firehose but there is some great information from some of the best that even I can wrap my brain around. From this thread and others I have read, I believe hybrids and a good single turbo will net you a very sweet 400 hp towing machine because they can be tuned down to your goal instead of maxing out a set of 160 singles. As in 160/100's (stage 2).

If you would like an option in the 360ish hp range, do a search on WhiteBuffalo 's set-up. If I remember correctly, he has a Van Turbo and a set of SWAMPS 175/146 single shots (stage 1.5) and pulls a sweet 5er all over the U.S. with Tony Wildman tunes. I'm pretty sure with PMR'S.

Casserly and Clay are running a great deal on hybrids right now and if I had the cash I'd pull the trigger in a heartbeat. Like Jason mentioned, the tuning capability on hybrids is amazing. The key is, proper tuning from all I've learned here. The only way I'll get them is if I hit the lottery but I'm keeping faith.

Wow! Spent an hour on that... I think I was able to vaguely follow along. Man, I wish I could talk to some of these tuners to get them to clarify on this stuff a bit.

Here's a pretty god link: Injector Info - PowerStrokeNation

I still can't figure out if I want a hybrid or an AC with nozzles... I really don't want a ton more power than 400. Unless hybrids utilize the fuel better and make it efficient fuel-wise, then AC's with nozzles sounds like the way to go.
