i am trying to put together everyhting i need for a turbo car i want to build. its going to be a 370 on a 80mm turbo 14-20 psi looking to make atleast 800 rwhp and is going to be on a stock pcm 98 trans am.
from what i understand i can run a dual pump in my stock tank that will support my power needs. racetronix high impedance 79 lb injectors should be enough.
now for some questions.

will i have to run a -6 or -8 feed line from the pumps to the rail or can i use the factory hard lines?

will i need to run a return line? if so what size line.

will i need to use a aftermarket fuel pressure regulator, if so do i need a boost ref. one?

will the 79lb injectors be enough 20 psi

is there anything i am missing

 

I have a complete kit for your application if interested.

I recommend a -8 supply & -6 return for good pressure control. Many have reused the stock supply line, but I prefer to play it safe when it comes to fuel systems.

I always recommend boost referencing as it allows smaller injectors to be used. For 800rwhp, the 60's will even get you by.

Feel free to call me if you need would like to discuss this in more detail.

 

I am in a pretty much identical boat and a guy one here said the 79#s were at 3 bar so 4bar (typical ls1 pressure) they would be something like 89.

Might give ya a little help

 

dont wanna hijack but i plan to run about 1000+fwhp. with a 383 ls1 twin turbo. and plan to use 2 255 walpro pumps, -8 -6 lines but i dont know what kind of regulator. and 79 high impendance injectors can this be used or do i need bigger pumps and/or injectors? or do i need the versafuel and run more bigger injectors?

 

As Lonnie rec. we have made 1000rwhp with our Stage3 street setups dual Walbro pumps, -8 feed -6 return that is well over 1000fwhp. The injectors may get you by but it may be pushing them. Every setup is a little different.
