Whats the max power on a walbro 255lph

It probably been asked a thousand times before, but what power can i safely run on my 9 using a walbro 255lph pump. I have a GT3071R turbo to fit which is well capable of the 500hp im looking for. Spec of the car is as follows

9GT
Norris rod job
tomei 270 cams
1050cc injectors
Link G4+ ECU

Any help or experience would be appreciated.

500 should be ok on a 255, people have ran more.

It's not exactly expensive or difficult to replace with a 340lph tho.

Do not try to run it at 500hp as it will be on failing fuel pressure. Only run to 420hp to have any kind of safety in its supply.

I run a walbro 255 at 400/400. Hardwired is the key.

I'd defo run a walbro 400 or 450 at any more power Tho.... Or one of the aeromotive.

Anything over 450, even if hardwired, is not good.
Typically, fuel numbers in the map tend to climb up a mountain at higher RPM with a 255 over 450hp.
