I tried doing a search but I I have no luck. I typed in walbro max horsepower and walbro max and found nothing. How much power can the stock fuel line with walbro handle with an aftermarket fuel rail and 1000cc injectors.

 

On a dynojet, around 540whp/490wtq give or take a few hp....

 

so are people sumping their tanks to go past 550+hp?

 

I was reading this thread the other day, some cool info that might be able to answer some of your questions.

if ur gonna b running injectors that big, u might want 2 look into an AMS fuel system...

 

550 anything pass that good luck with your rebuild.
