If I run a walboro 255lph pump will I absolutely need a fuel pressure regulator?

btw car is a bolt only car and plan on running a 150hp shot in the spring.

 

Are you asking "do I need to keep the fuel pressure regulator in my system with the Walbro pump"? = YES.

Or are you asking, "do I need an upgraded or adjustable fuel pressure regulator in my system with the Walbro pump"? = NO

How you configure the fuel system will depend on whether you use a wet or a dry shot.

 

sorry about that my bad..I meant a upgraded FPR

I will be running a wet shot,
will I need the FPR to control the fuel going to the N20 system or will the jets do control the flow?

Thanks.

 

the jets take care of the fuel flow for the nitrous system.

i run a walbro 255 intank and a 175 shot with stock lines/rails/REGULATOR/injectors. times are below
