6.7 Cummins NICE !!
If I ever gave up on my 7.3 that is what I would be looking at Dodge CC DRW 6.7. I wouldn't own a Ford 6.7 besides the newer Ford DRW are ugly....butt ugly !!!!!!!
But at my age Blackie and I are going to ride it out to the end. I'm sure I'll be taking a dirt nap before the truck heads to the bone yard.

I was very impressed with the #'s your truck put down. Now my E99 is rated at 250hp per the valve cover. But I would think that the E99 AB code injectors don't have more to give past 275 to 300hp. Where with a Late99-03 with AD code injectors there is more to be had past 300hp which your #'s back up. But it makes me wonder what the upper limit on hp/tq is on a AB injector????

 

Attempting to break the 250 RWHP barrier with stock injectors (AB or AD) since the pulse width becomes excessive means that all you're doing is making heat anyway at the expense of engine longevity.

 

Thanks for sharing that info. Now I am going to guess that you are saying that a 250 RWHP could be a realistic goal for a daily driver. If so would you say it takes a 60 or 80hp tune to get a stock truck up to the 250 rwhp? Last question if a stock truck / stock injectors can make a usable 250 rwhp what would the torque RWTQ be in the area of?

 

It depends on the driver. I personally am completely satisfied with that amount of power since I don't drive hard or fast.

Precisely. I'd say that a "tune" advertised somewhere between 60-70 extra horsepower is about as "hot" as one can realistically get before things stop working as designed.

It depends. Really. I'm not dodging the question. The source of the tune REALLY has everything to do with it. It's entirely possible to make 250 RWHP and put down less than 550 ft. lbs with one of these trucks. It's actually better for the engine, but one would have to relearn how to drive the truck to appreciate it.

Have you ever noticed (and it's been stated in this thread once for sure) that a 65-70 horsepower calibration will put down roughly the same horsepower on the rollers as a 100-140 horsepower one? If one were to look at the torque numbers on each tune, the higher horsepower one will usually make far more torque in the 1800-2200 RPM range because of the sheer amount of time it takes to burn the obscene amounts of fuel being injected into the cylinder although both tunes will level off in the horsepower department at nearly equal numbers.

Most tuning for stock nozzles is forced to max out torque around 2200-2400 RPM simply due to time and pressure constraints. Realistically, even though the horsepower won't be increased by much by putting 80% nozzles on stock AB/AD injectors, the torque peak can be put off a couple hundred RPM higher in the rev range and actually empty in a decent time frame. This is actually the route I'll be taking with my current project since I find them to be an awesome stock replacement setup.

 

Thank you I found this to be very insightful. Since I drive like an old man oh yea I am an old guy. LOL Besides my long term goals aren't high hp but to make it to the 500k mark and be able to do some towing along the way.
I did notice Bob had posted impressive #'s with his 65 tow and only a few more with the 120hp. Which it sounded like it took some tweeking on your part to get them #'s up there. Nice Job !!

 

Interesting... Anyone have dyno of a stock engine?

 

Where on Earth are you finding a Dyno where you are allowed to drive the truck? I watched epic dyno fail videos on you tube for a while before I went. BAD idea. Funny, yet scary videos though.

 

I have a dyno run using the stock tune of my truck. I think the numbers are close to what a stock truck would put out.

 

I do NOT know of a dyno that allows you to drive. Hence the reason my truck will never be put on a dyno. I only trust two people when it coming to driving my truck God and myself. LOL I have seen first hand and have watched a ton of Epic dyno fails video's over the years. It is enough to scare me straight. If I am going to blow up my truck I want to do it the old fashion way by pulling a hole shot at a red light or blazing down the drag strip.

 

When I did it, swamps 175's, T Wildman tunes and Van turbo, stock fuel & HPOP - 350 hp, 700 TQ on the tow settings. Only did the tow settings on that Dyno run since that's what the truck mostly ran in.

 

FWIW I think Bfife had 380 hp and 800 tq on a daily driver PHP tune. That was with manual tranny, 38r and Adrenaline HPOP. Not sure what else he has done.

 

I think your right about Bfife. I'd have to go back in my PM's to be sure, he loved them. He tows 18K also.

 

Thanks Rich that is impressive for a tow tune ! So with them #'s my next question is did you ever have egt issues with that tune towing heavy? And were you happy with the 175's or was there an issue with them after so many miles? Because somewhere down the road a set of 175's or new AC will need to be installed.

 

Ed, barney towed all over the nation with his and loved them. He did have it live tuned at PHP. And his is a F550 with united over drive, not made any more. Barney is Bfife.
And those numbers are correct I checked my PM from him.

 

I've bern very happy with them. I installed them back in 2007 so it's been almost 8 years. I haven't had any EGT issues but I did install the DI intercooler and the Van turbo prior to the injectors. Towing was so much more enjoyable after installing these injectors. Like I have said in the past - I would do it again in a heartbeat. We have towed our 5th wheel from Oklahoma to Florida, the Smokey Mntns, the Rockies, South Dakota and south Texas. Plenty of power to keep speed and rpm's over 2K while climbing grades, and passing power is available when I need to get around slower traffic.

The one thing I would suggest is to read the Remans vs new thread which I believe you are. I am not against remans but you are better off if you can send in your set to get upgraded. Or at least talk to Jim at Rosewood about your options.

As always I would suggest a regulated return and the Hutch mod. These will remove the air out of the system along with removing the dead head setup and feeding #8 inj the same amount of fuel under load.

I have experience with Swamps and Jim at Rosewood - A+ folks in my book.

After 8 years with this setup I am planning a turbo upgrade, I want to give her more air and see how a S300, S400 or Bell BASB turbo helps.
