Livernois Motorsports Fuel Pump Upgrade

[PropDr]

If you make 535hp without showing fuel starvation, why would you get a pump with higher flow capabilities.
If you do have fuel starvation, I'd first meter the flow rate at the fuel rail, or connect a pressure gage to see if there is a sudden pressure drop off.
If I'd had a pump that is sucking air at 1/4 tank indication, I'd first make sure that the tank actually still contains 1/4.
If it does, I would know that something is wrong with the pump or the installation.

i wouldn't raise this debate , but all those things tested by JDM and the conclusion is there is no difference in performance compare to stock pump.

Let me say it in a different color:
If your engine can not use more fuel, making more available will not get you more HP!

Totally get it now. Thanks for posting it in Red!

Hey MetroNYC,

I haven't said anything about doing the Livernois Fuel Pump upgrade because
I'm still in the process of getting a custom Dyno Tune once all my parts come in from Whipple for the 550 rwhp Tuning.
Also a fuel pump upgrade is not meant for HP increase as a mod, it is meant to keep up fuel demand if and when needed.
Having a non-return fuel system puts a lot of stress on the pump itself, being that it always is turning on and off constantly.

I do want to add, I have no issues at all with the pump and I've been running a full year with it.
I also can't comment on what JDM says about the Fuel pump because yours is not installed correctly if your running out of fuel under a 1/4 tank.
JDM talks a few times on the forums about the Raptor running into fuel starvation when hitting 550+ rwhp.
And JDM doesn't like B.A.P. systems, they are known to fail from time to time and burnout the fuel pump prematurely.
These few comments from JDM also helped in my choice to upgrade the fuel pump.

It's a shame you didn't let John the SVT Tech at Hassett Ford do the Fuel Pump for you but I understand you were tired of the long times they held your truck.
Even John the SVT Tech said, this is the pump all the Mustang guys upgrade too, it's a very well know pump in that community.
And these guys run two of them with a dual B.A.P when going over 1000 rwhp.

Now the debate maybe that, "do you need to do this upgrade on your SC Raptor with a stock block?"
That's a tough question and one I can't answer for everyone.
Hopefully after my dyno runs I can expand on this, and give you guys feedback.

One thing that I'm looking for is, we all know that you can add and remove fuel in the SCT software.
But I haven't been able to get a clear answer as to, "can you increase fuel rail pressure and increase duty cycle of the fuel pump using the SCT software?"
Or are there other mechanical upgrades other than just the pump?
And the second question is can the Raptor's stock fuel rails and lines handle said increases.
This would certainly make a difference on using a stronger fuel pump.

I also understand your frustration MetroNYC with your build and the money you have handed out with trial mods.
It's a learning curve for everyone when doing new upgrades and you got into the game early.
This was always one of the reasons I never did LT Headers and most likely never will. Well never is not the right word, If I feel the need a bit more HP all bets are off.

Being that I'm on call 24/7 and my Raptor is my DD, I cannot afford to play around to much.
This was my main reason for doing the pump upgrade, I'm all for doing what I can to make my build as safe as possible.

If I get a second car as a beater then I may play a little bit more.
But I honestly can't see myself driving anything else but my Raptor.

I guess this is where we are at with it, just to make it as straightforward and factual as possible.

#1 this fuel pump is only intended to be an upgrade if you have exceeded the limitations of the stock pump.

#2 if you are past the limits of the pump, the injectors might have enough headway in them to offset the loss in pressure associated with exceeding the limit of the pump. This is not an ideal situation, but it does keep the engine happy.

#2a if #2 is true, then putting in our pump will keep the pressure drop at bay, but if the injectors were picking up the slack then you aren;t going to show any change in performance. Only durability.

#3 we have this pump in builds approaching 700hp (the limit of the blower) and it does exactly what we need it to with no pressure drop.

#4 never have we had an issue with running these out of fuel prematurely. As eluded to above by another member. Either A. You are actually running out of fuel at a 1/4 tank, which means that the install is done improperly. or B. You actually are empty, while still showing a 1/4 tank, which means the install was done improperly.

Just one question, are you talking about bhp or rwhp?

 

[MTF]

Well we all know that Biggest put down 778 rwhp with the 2.9L Whipple!
So it's not the blower that has a certain limit but a stock 6.2L will only get you so far.
What a stock 6.2L blown with a SC can do really do hasn't been pushed to the limit and it's not going to be me to find that out. LOL
And I can't realistically find out with stock exhaust anyway. Probably melt the cats before anything else.

 

[metronyc]

I don't give a **** about there bolshit pump or products all i care is customer service i send them few messages and emails and make two phone calls but couldn't get any answers or resolution . Thank you all the people that try to help with advise but I'm looking for professional solution and not home self made mechanics .

Sounds like you're looking for a solution to a problem that doesn't exist.
