Hardwired pump running out of fuel??
What’s up everyone,
So I went tuning my car and my hardwired walbero 450 is running out of pump at 540 whp dynojet. I’ve seen a lot of people run hardwired 450 to 600+ whp dynojet. Even my tuner said that it’s weird how mine runs out of steam at higher RPm. Any idea of what it could be? I have a built 2.4 with FP black and all the bells and whistles s2 cams, 2150 injectors, fuel rail, intake and exhaust mani. I’m not really sure what’s goinf on. And FYI the pump has maybe 6k miles on it not that old I also got a new sock for it before the install. I did check the part number it is the high flowing one. Any idea what could cause a hardwired pump to run out at high RPM? I couldent finish my tune due to low flowing pump.
Any help would be appreciate it.
Thanks.

You should not be maxing out that pump at that level.
I run the HP 450 and I am just now dropping fuel pressure past 8,000 rpm (approx 6psi drop) at 570whp Mustang, 640whp Dynojet. OEM fuel rail, OEM FPR, OEM feed and return lines.
I have my 450 in a surge tank, with a torqbyte fuel controller and 10AWG wiring.
