The build is not finished yet but If Im running a stand alone for my nitrous fueling would a single walboro 340 surfice? Will be running on pump gas maybe race gas instand alone on occasion

Single Walbro 255 intank Fuel pump is good for 650 HP. Max.
I have an LS2 404 ci. Stroker Nitrous Motor that makes around 650 HP on the Juice with a 150 Shot of Nitrous. Im not running a stand alone. The Single Walbro 255 supplies all of the Fuel for my motor & nitrous system. I am Maxed out now at 650 HP.
You could always run Dual Walbro 255's if you modify your fuel pump bucket. Make sure you run the upgraded Racetronix Fuel pump harness & relay with the 255 Walbro for safety & max fuel pump performance. Lonnie at Lonnies Performance is the Guru on Fuel systems.

Stand alone Fuel system along with the Single Walbro 255 intank pump would be the way to go at 700-800 hp.
They say Low Fuel pressure supplied from stand alone works best with the nitrous system.

A stand alone will continue with a fuel pump. Usually a walbro 255 or if low pressure a Holley blue or something.
My car makes 570rwp on motor with a single walbro 255. Spray 200 on top of it with a stand alone that has a walbro 255.
I have twin walbros in the tank from when the car was procharged a long time ago. Before j bought the stand alone I had the second pump to come on when the nitrous was activated. Worked fine. But was only spraying a 150 shot. Never went lean or dropped fuel pressure.
