30% nozzle on stock HPFP

I would like to see this also. I have a set of 30% nozzles sitting here if you need them Steve. I'd be more than happy to send them to you if you're willing to do the testing.

I'm game! JD is gonna get it all together and then up to Mike to dial the gate in and get some baseline data. We'll swap nozzles and repeat to see if there is in fact difference in the data or not

It would prove that if it works that all the bs about "can't be done" isn't true. It would prove that if he uses a new stock hpfp and 30% nozzles holds a 2.1 tune and makes more torque or pulls harder down low then all these people can quit telling everyone they are stupid for doing it. If it makes the same power with less timing and lower EGT's then that would be nice too.

Idk if it works or not. But I think a truck tuned for 30's and a stock pump will not loose power.

If elite says their 72 made 30hp over the 71, do you then tell them they need to duplicate it on 10 trucks? Seriously?

I'm tired of all the guys saying one way or the other with no real experience. I've seen 30's hold with the right tune. Big deal. If your truck won't maintain with stock nozzles then your hpfp is ****.

I am ready for this to be proved or disproved.

I tend to agree. I'd still like to see what others have but it is looking pretty scarce for data at the moment. Which sucks but isn't shocking. Only way to know for sure is to test it for ourselves.

My stock fuel system wouldn't hold any more than 23.5 on spartans 310 tune before my build. Added 15% nozzles and lpfp with fuel bowl delete. Now it's holds 25k all day on Eric's x race, my hpfp only has 47k miles on it though. Just my experience.

Do you have ported rails?

Good to know, if I can run 22-25k rail I'm happy. I did some testing this weekend, X-race my truck will carry 22.8 at the lowest yet my Gearhead race will carry 24.6 at the lowest. Both tunes are making similar power as my trap speeds are identical with both tunes, 104mph.


I really want to just go duel fuelers BUT if I can make decent power with stock pump, Elite 72 and 30% tips I will still be able to fit into a pulling class here local to me....Even if it means I buy a new hpfp from Ford to make this work.

Seems like aeromotive pumps instead of airdog, fass, etc will maintain bigger nozzles.

No ported rails on Beans truck.

For those maintaining, who's tuning are you running and at what pw?

 

[Morgan@Midwest Diesel & Auto]

Ok guys Brian warning and I are going to do this as well. We talked testerday after he saw this thread. He has been wanting nozzles anyway. We are going to do a baseline and then doing the swap. Hopefully I can get Matt on board to help with tunes.

When I originally did the test, "Maintaining" was defined as running an all out tune, just as any other truck would. An X race or 310 type tune at 2.3us.

NEVER SAID YOU COULDN'T BACK PW OFF TO GET BACK TO 24,500PSI.

And morgan this isn't directed at you, I just quoted your response lol.

How soon Morgan?

It really seems to me like there is a trend starting to show...

Seems like no matter what nozzles are in the truck, a pump that just maintains is only moving enough fuel to make XXX hp. Seems like whatever nozzle is in the truck, you're limited by fuel supply, not the nozzle.

Strokin6.4 said his truck made 691 with his 30% and a 472. That stays pretty well in line with my truck on stock nozzles (694).

To stay on the same page as mink...Someone needs a single HPFP that will flow enough to support small nozzles... or something that will drop the duty cycle on stock nozzles

It's in the works. Whether it lives or not is the real question

,

Like Dustin said no ported rails. But also remember, I'm only running 15% tips.

 

[78f100]

I have no numbers to back it up but I lost power by going to a 60hp= 15% over nozzel when I had the stock 110K mile hpfp. I could only maintain 21K rp on xrace. I ran the exact same 1/8 mile time after adding, airdog,elite bowl delete, II 71mm turbo, and the 15% nozzles, as I did tuned only.

Similar to my experience. I only had about 45k on my hpfp though.

And experiences like this make me want to just put dual fuelers in and say to hell with pulling in the smaller classes.

Gotcha.

I'm not doubting that a stock hpfp will have problems holding a 2.3 tune with 30%. But my thing is, can you make any gains from doing so with an appropriate tune? If there is an upside then it will help others. If there isn't then there is a definite case for dual fuelers on anything but stock nozzles.

We will see.

I think we tried 8 tunes on the dyno that night. Matt from Gearhead fed me tune after tune trying to get my truck back to even the same power it had before with no dice.

 

[Strokin6.4]

I was on extreme street when I dynoed mine held 24,500 psi rail pressure. Eric seems to think whatever pw it takes to get around 22,500-23,000 will be your most power with 30% nozzles which for me is his 2.0pw custom single tune I have. Now I'm sure if you can maintain atleast 23,000 on a 2.1 or 2.2 you'll make more power but most don't. I know for everyday driving my 2.2 tune spools my 472 10x better than stock and probably average a drop in egts of 100 degrees but it only maintains 18,000ish psi at WOT. But going by JDs test it doesn't suprise me seeing the added fuel helps more at low RPM even if it won't maintain at WOT

So what I read is:

2.2pw - carries 18,000 rail.
2.0pw - carries 24,500 rail.

That seems like a huge difference, I'd love to see those two tunes compared at the track or dyno.
