Unfortunately, I think the time for injectors is here, my truck has started to smokes quite a bit on startup, and the exhaust is RICH. Also I have been kicking around the idea of upgrading injectors anyways.

I can't figure out how to update my signature right now, so here is the rundown. 4" exhaust, 6637 intake, new boots all around, rebuilt turbo, HPx, FRx, Hutch and Harpoon, Melling LPOP, and lastly, I think, my Hydra.

If and when I do injectors, I plan on having gauges on, or gauges ready to go in. My thoughts are Pyro, maybe dual, FP and potentially boost. I have torque pro for everything else right now. I have also been considering putting a new compressor wheel in my turbo, aftermarket of course.

I am looking to get to the 400 to 500 hp range, more towards the lower end of that spectrum, however I want to be able to tow 20k without burning her up.

I always thought a set of stage two injectors would be good, but I am completely open to anything reasonable. I would like to know what injectors you would recommend,and where you would get them from.

Thanks for the help,

Plenty opinion to come. I'm not sure how much fuel it takes to make 400-500, but that Hp range requires more air than a stock charger.

I think 175/100 might get where you want to go. The more I read about the 100% nozzle, the more I'm convinced that is essential to keep EGT lower at higher power levels. But common consensus is that heavy towing above 350 Rwhp, puts strain on the driveline.

 

Dan,

my plans to start would be to get injectors capable of that hp, and basically detune my engine to a point where my stock turbo could handle feeding it. After getting a capable turbo I could then have it tuned to make better use of its internals.

Also I forgot to mention, the 20k loads would be at low speeds (less than 30). At what point would towing be considered "heavy" for our trucks though?

 

20k...that's heavy in my book.

 

I agree, it is heavy, but it still needs moved and currently, the truck works hard, but she can handle it. At increased horsepower I'm sure things could start to fail faster than at stock, so would it be worth shooting for a truck maxed out at 425...? hp but can be detuned to say 350 for the heavy tows? Is this attainable or will have I have an unresponsive slug by trying to get a large horsepower spread like that? I can't foresee that happening, but I don't know..

Thanks,

Baatzy

 

It can be done. It's all in the tuning if you have the right components.

 

Barney dose it, I believe he pulls 18K around the country. He has swamps 175 injectors and PHP live tuning. Puts down 400hp and 800 Ft lbs. He dose drive F550 with 488 gears and after market OD. He has the 38R turbo too.

 

The drive line (not the driveshaft though) on a F550 is a BIT more stout than a 250-350 SRW, and more than a 350 DRW. The 4.88 helps reduce strain as well.

 

Im looking for the same thing but only towing around 13k, om going with 175cc with stock nozzles till i get a turbo then throwin a set of 30% nozzles on. Thinking of going with tonywildman tunes or no limit tuning cant decide yet haha

 

There was a post hiccup... and it happened right here.

 

100% nozzles are much better for EGTs, when dialed down for heavy tow. I don't always recommend going the way I have... it's an expensive and involved upgrade to do it properly. If I were to pull 20K with Stinky - I think he could manage it as far as the engine/transmission goes - but my 4X4 F250 with 3.73 gearing is lacking in the rest of the departments.

New IH Stage IIs will get it done, but be prepared to strip the engine and start over... as I had to.

 

I'm not too worried about the pickup handling the weight, its done it quite a few times already, not always gracefully, but, its done it. What I would be worried about is the drivetrain, specifically u-joints and rear end gears holding up. The rear end gives me no reason for worry now, but I have seen too many gear boxes shred their gears in the last year to believe that the rear end will stay problem free.

So, its sounding like 175/100 or 160/100 so far and I have heard both Swamps and IH mentioned. Any other inputs? Also new vs remans, I don't see may sites advertising new injectors, but I imagine they could be had. After reading some of Rich's stories I would be inclined to go with new injectors, but I also haven't seen many other stories like Rich's so that leads me to believe that those problems are not common.

Lastly, I'm not too worried about having to strip the engine, I got a bunch of that done over Christmas Break this year. Took the engine out and cleaned it, replaced CPS, ICP, EBPS, passenger fuel line, all fuel and oil o-rings, injector o-rings(will be irrelevant with new injectors) plus all the stuff I mentioned above. I should also say its got bellowed uppies on it, and a pedestal with rebuilt EBPV.

I can't think of much else that's new, but I am sure at any rate I'll still have to fix something with more ponies under the hood.

Please keep the ideas coming on injectors,

Thanks,

Baatzy

 

The only "new" larger cc single shots are the 160's, the IH AC code. PIS, Full Force or Swamp's could install the 100% nozzles.

 

Wrong on single shots. FFD has or can get 205/100 new single shot injectors. I intend to try them soon, I hope. And Barney has no EGT problems with his 175 stock nozzles, 38R and PHP tuning. This is all good information I just wanted to make a few other points.

 

Good to know....are the new? or new/new? (sorry inside joke)
