How much rwhp will a Walbro 255lph support?

[blueoval92]

that inline pump that 92 notch has from procharger is a 255 inline and he says he's maxed out using both pumps! for one, using dual 255 inlines will support more than an aeromotive pump,so 92 notch would have had to go to the aeromotive eliminator pump a long time ago. and for two, insurance! at 560rwhp with 15% drivetrain loss thats roughly 644flwlhp with stock lines and rails!!! and still safe because he has two 255lph pumps and 50's. you can never have too much fuel IMHO, fuel is what makes the hp! rydeon you might not require that much with your combination yet,novi 2000 and more boost and you would! hey 92 notch i believe you're already thinking lines and rails for the car! p.s. it's all for piece of mind, and your motor! j.

Stock lines and rails, dual 255LPH walbro's (intank/inline GL392), 36 lb injectors: 11.5:1 A/F ratio up until 5400, then slowly climbed to 12.5:1 A/F around 5700. Made 450RWHP. I think my injectors are starting to max out after 5400, but im happy for now, just set my rev-limiter to 5600 and go.

I just dyno'd last Wednesday at 442 rwhp SAE and 421 ftlbs with just an intank GSS340. A/F was steady all the way and smooth...was 11.2 to 1 from 5000 rpm up.
