Max lift pump pressure?

[Sledheadxp800r]

I'm relocating my ficm and running it dry. Now that I don't have to worry about my ficm how much lift pump pressure can I run before it starts causing issues? This will be on my puller that gets trailered everywhere and sees very short run times.

anything over 12-13 psi on my lb7 makes it act up. I run mine at 11psi

 

[smkndmax05]

I run 24 psi on my DD, no issues. Tuning needs to be adjusted.

My LLY see's 20 with the FICM and still no issues.

I run 18psi with my aeromotive 2000. Truck is a sledpull only set up with the ficm on the return side of the fuel system.

I have mine at 6psi. No need for any pressure at idle. When you fool with the regualator tables to compensate, you will most likely take away responsiveness down low

turn it up till it effects the idle, I used to run 11psi with stock cp3 but have to run 8psi with the lbz fpr to keep actual RP close to desired

I think I'm going to go with 2 of the new fuelab velocity 200gph setups. They're like an airdog or fass but they use a flow through pump. They are regulated at 8psi and all the pumps come with a certification sheet with flow specs.

Like said above , turn it up till it changes things

 

[Sledheadxp800r]

Those new fuelab setups are pre set at 8 psi and are non adjustable

 

[TNRGreene]

Both my trucks are regulated at 12psi.

I just put a raptor on mine. Psi was already set a 20. Seems to run smoother at 20psi then 12psi that it was at with the ppe

2? Holy smokes son!

I crank it up until I see 8,000 psi of FRP at idle. Its somewhere around 30 psi.

Yep go big or go home :roflmao: I figure I run 2 now then I'm pretty much set for anything later on down the road

Here's the fuelab 200gph system if anyone is interested. Part # 30304. The install kit does not come with this part #

 

[cwmeaux1]

My lift psi is 22 on my Lbz and it's my dd/race truck, with no issues

 

[Subman]

I run 18 on my FASS 260 in my LBZ

 

[embs200]

how could one run higher pressures on ficm trucks. any mods i could do?

 

[Redbowties88]

Bypass the ficm. or just crank it and deal with a possible goofy idle. what are you looking to gain though with more pressure?
