vx ss fuel system

I have the standard fuel pump with bigger injectors I have currently 411rwhp and its fine atm. Just want to know how much rwhp this will be fine before have to change it. Guessing not much more?

How much power are you looking for?

I personally wouldn't push the stock fuel pump past 300rwkw but they can support about 310rwkw-320rwkw depending on age, condition ect. you have roughly 300rwkw now.

I will be doing more work to engine later on and prob install a bosch 044 external atm its just had a brand new pump installed.

Use the internal pump as a lift pump for a surge tank feeding the 044.

What engine mods have you done and whats the future plans?

You would only need to do the internal, something like a walbro is good for 550rwhp
