Flux 1's and stock motor .......

[JHardwick]

Do they work on a stock motor? The website shows that they are geared toward a motor with TST/pressure box stack.



I have a Quad box, but don't run it all the time. Will these tips work stock, or do I need to run the Quad all the time to get full benefit?

 

[JHardwick]

... ... ... nobody?

 

[RobertP]

with a set of small inectors i think you will be ok. im sure you will feel it more when the quad is on. but there is no reason why you shouldnt get a set. you will see a fuel milage increase with them also. they will probably run a little hotter than the stockers in the egt department. all in all it will be a good investment.

 

[JHardwick]

Well, I scheduled 2 weeks off to get this done. I'm also going 4" all the way. I currently still run 3. 5" from the turbo back to where the muffler used to be.



I have to believe that these injectors will "pep" things up a bit, even stock, over these 300,000 mile injectors.



I just wish I could get my radio to play nice with my Quad #@$%!



I put the Quad inside a copper jacket with a ground strap and noticed some improvement. After that, my radio guy added chokes to all the Quad harness stuff with some improvement and no copper jacket ... ... ... ... ... ... ..... I need to re-do a copper jacket along with the chokes ... ... ... ... ... ... or get off the radio :-laf

I'm thinking of the same setup with the Juice and a Goerend transmission, I've also got a Quad race box I'm thinking about sending back for a pressure only mob similar to a EZ for a stack. Report back on the results as this is what I might have in the future. Also what is the turnaround time for the the full rebuild injectors-I read it was up to 2 weeks which I couldn't do. But that may have been read out of context on a diffn't thread.

 

[BManier]

if ya can let me know how they do I was wondering about those injectors

I was told it was a 1 day turnaround, and I'm counting on that. I already have contracts with deposit money for my next trip. Aside from that, the one lady wants to see her horse get on my trailer, and has a plane ticket to meet me at the other end to see her horse come off of my trailer.



My mechanic should have them out by Tuesday, and I'll be standing there with a box already labeled and ready to go. I should be back up and running bt the weekend.

 

[JHardwick]

I'll know here in a few days what my impressions are empty. I had a bunch of stuff to get done in my 2 weeks of down time. I'll do a short trip to the east coast and back next week for a full power/mileage comparison with a load. I'll be running with/without Quad as well.

I suggest you run your injector questions to wade over at NGM Diesel. I wanted to send my low mileage injectors out to have them redone too and I can let my truck sit for 2 weeks, but its not neccessary. I will let wade find this post thread and clarify alot of misconseptions with "high mileage injectors" and the way Industrial Injection does their injector work. Wade is the only I have found (tried several shops & got lots of aggravation) That I have full confidence in.

 

[DerekW]

and NGM Diesel is an authorized dealer and will hook you up. Wade if your reading this also contact me I am ready to spend more money$$$$ also hows my truck? PM me and let me know.

I just had mine pulled at 300,000.



A couple months back I dropped a cylinder twice in one day. It turned out to be a connector problem and not an injector problem, but I already had my mind made up to pull them.



I just got them back from F1 Diesel Thursday, and picked up my truck yesterday. I'll be heading out on a 3,000 miler tomorrow. I'll be running I80 all the way across PA with 4 horses, so it'll be a good first run with them to check power and mileage. If things look good on the way out, I'll through my Quad back on for the return trip.



First impression was how smooth the idle was. They did find what they called "pressure related wear", and had to do some minor repairs as well as add the Flux1 tips.

Well, my first tank was 10. 69mpg. I almost always do 11. 50-12. 00mpg average over 3-4 tanks or more. I'm not going to get excited until I run a few tanks through to determine an average.



Once I get to the halfway point, I'll set the Quad to "60" and run the last half of the trip.



Power without the Quad is not earth shattering, although I didn't expect huge gains without a box anyway. The motor is smoother for sure, both at idle and under power.







DerekW,



F1 Diesel did a 1 day turn around, I'm not sure where you think there is a problem with that? I've had a few hundred thousand miles to see what would develop in the common rail injector world, I know the difference in EDM and honed injectors based on 20 years of machining experience, and so far I'm comfortable with my decision.



BTW, I got my injectors back (no core) which have performed flawlessly for 300,000 miles.

 

[JHardwick]

Well, my trip got cut short and I only did 1,800 miles instead of 3,000 miles. I've been home since Wedensday morning, but I didn't drive my truck all week.



I just today took it up the road to the truck wash and to refuel to get final numbers on my last trip.



Total trip was 1,833 miles using 166. 094 gallons of diesel for an average of 11. 04 mpg.



The first half of the trip was injectors only @ 927 miles and 88. 023 gallons of diesel for and average of 10. 53mpg.



The second half of the trip was with injectors and Quad on 60hp @ 906 miles and 78. 071 gallons of diesel for an average of 11. 61mpg.



I-80 doesn't have any real hard pulls, but it is 70-75 mph the whole way. GCVW was in the neighborhood of 18,000-20,000#. I was ~1,500# or more lighter on the way home and had some 55-60mph state road travel as well. 4 horses out and 2 horses back.



Also, my truck never shuts off when I'm on the road. I've left it run for 10 days straight before. While I sleep, eat, fuel, drop off, pick up ... ..... no matter. I'm not sure what 6-8 hours a day of idle time does to my mileage, but I need heat and/or air to sleep.



I'm leaving in the morning for a 6,500 miler ... ... ..... this time I'm leaving with the Quad on 60hp.



My first impression of the injectors without a box before I left was a little lack luster. You can feel them, but it's not an explosion of power. However, once I got a load on it, they pulled harder and smoother than the stock injectors. I think if you put a 40hp box on your truck, the fuel curve is remapped making it peaky and more noticable, seat of the pants. The injectors are working on the factory fuel map and not as peaky. They do pull harder with no box.



Once I turned the Quad on, there was no doubt that they were liking the pressure and timing. They do produce a little smoke without a box, just a warning.



This trip, I'll be headed to Texas, back to Maine and then back to Ohio, so I'll get some flat ground and back into the east coast mountains. We'll see what mileage is, but I doubt that there is gonna be any gains. F1 Diesel doesn't advertise MPG gains, I just thought that through efficiency, there might be some improvement.



Overall, if I had it do all over again ... ..... I would. We'll see what this next trip holds.

thank you JH and we appreciate your honest feedback.

great post thanks for all the informantion

 

[DaveRodgers]

Good post, thanks. Been thinking of the same since, at times, I tow in the 18-20k GCVW range.

Any noticeable difference in egt's?

I'm gonna do some more MPG numbers, I'm 1,200 miles into this trip. Right now it seems more sensitive to the 55mph-70mph speed difference than I remember it being. Right now I'm @ 10. 77mpg after 3 fillups.



EGT's are very manageble, I pulled Jelico southbound on I-75 last night, with the cruise set on 71mph. Boost was 22-24psi, egt was 1100*, spiking to 1150* once. Highest I've seen in 6th was 1200*. If I pull a long grade and rev it to the redline in 5th, I can see 1300* if I want.



The thing I like the most is getting 100hp and only fueling to 60hp. Reliability is very important to me.





Just calling it like I see it Bob

great post, with good info and inpuy. I am in need of some new injsctors also.
