Bigger nozzles on stock fuel for now

[Stroked777]

I will be taking my valve covers off soon to do rockers and was thinking I would do nozzles while I'm in there, but only if the following statement would work... If I was to get bigger nozzles could I still run them with a low PW tune and still make the same power as stock with a 2.0-2.1 pw tune? I say bigger nozzles with a low pw tune so I can keep the rail from draining and keep RP still around 23-25k. Has this been done with good results and little to no loss of power? I do plan on doing dual fuelers in the future but figure. Would kill two birds with one stone. If this is possible would it work with 30%s

many will say no. I ran a 2.1pw innovative file with 30s and a a-1000 low pressure and fuel bowl delete. I was maintaining 25k for quite a while. then the pump dropped to only maintaining 21k for a long time and failed with 60k miles on it. whether it just failed from age or the strain I'm
not sure. but I did in fact maintain on 30% nozzles and stock HPFP for a while.

You could run 15% and maintain, not sure the power gain though.


I can get you setup with nozzles if you'd like.

What would 15% support? My goal is 700-750ish hp

i havent seen many dynos on 15%.. but simply on stock fuel and a larger charger setup high 600s. ive seen one truck with 30s and a 71/59 dyno 705, but no real track times to back that.. but if you want a solid 700-750, you will need dual fuelers.

dual fuelers is in the pans, i just was wondering if i can run bigger nozzles for now on a low pw tune until i get a dual fueler set up, i figured i take the valve cover off once and get it done, plan on getting a 76/59 set up

 

[powerstrokin15]

yes until you get dual fuelers you can run a lower pw tune and maintain with 30s. it may not make much more power over stock fuel, but it can work yes.

thanks i aappreciate the insight

I ran my drag truck all last season with elite 110s and a stock single injection pump. Made 730 on fuel and I sprayed it to 1006. I custom tuned it with a low pw and it worked good. It was always really clean and responsive.

looks like i will be doign nozzles as well, im just glad you guys were picking up what im putting down, i didnt think anyone would get what i was trying to say. but in my head it seems it should work

mike what was the pw you were running with 110s

would this put undue stress on the stock pump?

i dont see how if you cut the PW but still is injecting the same amout of fuel as a stock one would

 

[powerstrokin15]

im not sure.. but my stock pump did fail. im throwing a brand new one in and trying again.. so we'll see.

i was running a 1.9ms street file fine. but the majority of my driving was spent running a 2.1ms race file from Eric@IDP, and putting it under that PW to try and make full power might have strained the pump too much. and like i said. it maintained for quite a while just fine.

now i have to figure out 6 hole or 8 hole LOL

 

[powerstrokin15]

theres a thread in 6.4 tech i believe on this.. check it out. no advantage of 8 over 6..

now i have to figure out 6 hole or 8 hole LOL

there is a thread someplace that talks about that. iirc MPD six hole flowed a decent amount of fuel

mike what was the pw you were running with 110s

1.68 pw maintained 24,600 psi perfectly

would this put undue stress on the stock pump?

Not that I have found or seen.

 

[Stroked777]

1.68 pw maintained 24,600 psi perfectly

110 are 60% correct?

No 30%, 150s are 60% I believe. Jd or someone can correct that if I'm wrong

110s are a 50%, 150s are 75%

Your definitely gonna make more power with dual pumps. But if your tunning is right it does work well until a guy can afford dual pumps.
