The idea of a 610hp 4.7 is awesome! I hope I can make close to that someday. I've already had somewhat of a running dialog with KRC on some of their 4.7 goodies, and it's really good to see somebody putting some of them to use.
I don't think I'd put too much faith in that 147 to 157 rwhp number regardless of where it came from. There are far too many low 15 - high 14 second stock trucks to believe otherwise.

Chris C,
I really believe all I read and none of what I see.
My 4.7L Bone Stock, Dyno'd at 202 hp, now I seen that I will not believe it, but I read from mopar that it only has 147 hp, now that I believe.
Later,

My 4.7 just dyno'd at 233hp/300tq at the rear wheels and that's with $1050 worth of mods to the engine/exhaust.
That ain't much, but it's pushin the limits of MY personal budget.
(for those of you who are trying to figure the math.... that's 275hp/352tq at the crank, which is 40hp/57tq more than the factory rating)

Throw another $475 on it (NX kit)... and you'll be in the 375 range! About 325 to the rearwheels!

The Cummins Turbo Diesel guys call that "Sniffin Drugs" and I am trying to stay drug-free.
But don't think that method hasn't crossed my mind.....
I'm actually waiting to see what you come up with as a pricing point on your Turbo Kit for the 4.7's..... I was hoping for a max of about $4500. That'll get me into the 400-450 range (340-380 at the rear wheels).
Heh.
I know you can't say much about certain things at this point, but have you got a release date in mind?

can you list your mods. I think you have pretty much everything but a turbo don't you? (HO parts, 3" exhaust, headers, 3"cat, PCM, TB .. did I miss anything besides the little stuff like plugs and thermostat etc?) ..
More importantly to me though is: what RPM did you find peak numbers? Whats your elevation?
here at 3500' I dyno'd stock with 300 rwtq, 190 rwhp ... torque was at 3000 RPM, hp was 3700RPM .. as you can see, I have a ton or RPMs to play with at this altitude, I'm hoping to push my torque band up 500-1000RPM .. that would net me over 240 rwhp with the same 300 rwtq.
I'm looking forward to a turbo kit too.. but I'm poor right now and have to wait a year or so :(

I have pretty much what you listed:
70mm TB
3" single exhaust all the way back (3" cat)
Ford Motorsport 21# injectors
HO cams
HO intake manifold
Leach Flash
Volant Cold Air Tube (no air filter for dyno run)
Removed viscous radiator fan
Short belt (no alternator or p/s pump for dyno run)
Autolite 3923's
180 deg t-stat
Mobil 1 5w-30
56,300 miles
Dyno'd at approx 1000 ft elevation on a rainy day in an open dyno cell (no climate control).
I suspect that it's still a bit rich at the top end, and Leach did not fully remove my rev limiter, so I am working on that part.
Peak hp was at 4300 rpm +/- and peak tq was at 3700 rpm +/-......
Next up: headers, head porting (HO or stocker cores??) and KRC 218 cams. May also be time to get "customized" with the Leach flash. We'll see.

No release date yet, still bringing things together--- already have 3 people that have said they would pay for the kit upfront (YIKEs! This is kinda like holding a steak up in front of a bunch of hungry wolfs!) Have told all 3-- keep their money, wait until we have a release date.
Have a local guy that's ready to go, so it's a matter of getting things lined up (product, sources for all of the items for the kit-- make the installation manual-- figure out who can install the kits--). The whole thing... It won't be a rushed item to say the least. There's a lot of "WHAT IFS?" to deal with.
Also have legal issues to attend to-- example: Billy B. orders a kit, installs it incorrectly-- blows something up-- then wants to sue us/me... Gotta make sure the liability issues are addressed. I am confident to say, the kit has been running for about 1 year-- so as long as the installation done correctly, things are checked throughly-- and people don't go hog wild turning the boost up-- it should perform fine.

I'll be honest with you, Sam, I am a year out from buying a kit (financially), but I am very interested in buying one.
Here's another question: Is 10 psi going to be considered "hog-wild?" Or will the kit include the "appropriate fuel system upgrades" to run this much boost? I don't plan on suing somebody, but I do plan on hitting at least hi 12's in the quarter.
PS- I know this guy out in Phoenix that can produce that instruction manual. I'll have to hook you guys up. BwaHahahahahah!

yeah I imagine those injectors may be a litte rich .. did you notice any difference after installing them? were you lean/pinging before? .. was there an A/F gauge on it when you dyno'd .. from what you have, I'd expect your hp peak to be a bit higher (4800-5000 RPM or so) which would also indicate running a bit rich .. but I'm just guessing. I bet the headers will help you out a lot. and some bigger down pipes ... kinda a toss up though, you may not want to get headers if you're holding out for the turbo .. depending on what they decide to do about the custom passenger side manifold .. maybe you could just buy one header! LOL
I'm pretty much in the same boat as you, except a few steps behind .. also about a year or more out from buying a kit, but very interested.
Sam: Are you going to offer the kit piece by piece or an all or nothing thing (i.e. can we opt for our own manual or electronic boost control .. or say an air-air intercooler rather than air-water .. etc.)?

Needed to have gotten an A/F reading during the dyno runs. Didn't really occur to me until i was on the way home. Durrr.
The reason for the 21# injectors is that Duner has seen/heard of several 4.7's suffering injector failure. When the factory (Siemans) injectors fail in the open position (let's say they stick open over night), that particluar cylinder fills w/ gas dripping from the open injector. Next morning, you turn the key, and the starter motor has enough strength to turn the motor over, but gasoline doesn't compress. Bam. The connecting rod bends, maybe a valve or two.
You now need a new $3500 engine because a $35 part failed. Ouch. So as a preventive measure, I got a set of FMS injectors.
But I need some more dyno time to get the A/F worked out. You raise a good point about the headers vs turbo-based manifolds. I will not be spending that $450 anytime soon, so I will have time to decide. Cudashoe posted that the headers made a huuuge improvement. He definitely has me thinking....

yeah I read his post of the big improvement. Got me thinking too .. that's when I came across that whole dilemma.
That doesn't sound like a good scenario for the injectors :( .. I think part of the problem is that DC overpressurizes them to begin with .. trying to turn them into 21# injectors, when they're really 19#. Is that all you swapped was the injectors? no other fuel control (fuel pressure or a split second ARC unit or something?)?

Yeah, i only switched injectors and I did it at the same time I did the HO cams/intake. So I cant' really tell the difference. The Leach problem is that part of the rev limiter is still in place. At 5500, the injectors are being shut off by the PCM (technically it's killing their duty-cycle) and it falls flat on its face. To counter that problem, the engine is just not making power at that rpm. But that's probably because of the rich injectors.
I'd really like to have power past 5500 rpm, so I am still trying to get in touch with Leach and get this thing reflashed. I don't think Tom Fox (leach's guy) does anything outside of the set program that they have developed. I am sure he would do some dyno tuning, but I am not driving from Atlanta to LA just to do dyno tuning.
I am looking at my electronic options (Split Second or Roe Controller) and trying to tune what I already have in place.....

When I talked to Tom, he basically said he could do what ever you want to it, as long as you're specific.. he always recommends starting with their base programs though .. and I think a re-flash will cost you $100.

Not to slam Leach, but they still haven't gotten my "base program" completely correct. Therefore, before i call him back, I want to have some specific requests in mind. Maybe I can get me a little custom stuff done for free.....
Maybe.
