i realli dont want to go threw all the trouble of fitting a surge tank and all the lines im after some thing i can just bolt in and fit the problem

i wanna get out of this the most cheapest way i can as well

On the cheap? Here's my suggestions to save coin;

1. Use stock pump and dont go for big power

2. 044 intank, tune for 380 or so rwkw and be happy with that power

im running a 044 intank, using a efi v8 falcon fuel sock retrofitted to suit the bottom of the 044.

simple install and no issues with 5 ltrs in the tank around corners etc.

only way to do it IMHO.

note the clear fuel hose i have mounted around the pump absorbs all the vibration, so its very quiet.

So does anyone know when the stock rail runs out of flow?

i had my car on the dyno for a tune yesterday and when we got to 400kw it started running into problems with fuel

we had a fuel pressure + flow gauge connect to the car while we were tuning the flow doesnt drop at all but the fuel pressure goes from 40psi to 60psi and then just drops back down to 40 instead of going higher it just drops back to 40 and the car leans out so we neva got to finish the tuning

fuel system is pretty basic

bosch 023 (rated at 700hp) mounted intake

SARD 800cc injectors

HKS fuel reg

Fuel pump for sure. Stock rail is good for well over 400awkw (maybe more, but ive had a few RB26 in here pull well over 400 with no issues)
