How much can one Walboro 255 support?
I have an rb26 single turbo with a breddy rail and 6 ID1000cc incetors. I am aiming for 500-550 rwhp on pump gas. Can a single walboro support the 6 1000cc injectors or do i also need to run an external push pump like a bocsh 44?
You didn't mention what fuel you are running so I will assume is is regular gas/race gas:
The walbro 255 will max out before the 1000s no doubt.
A good condition walbro has been known to make 500whp with about 550whp as the limit.... and IMO personally I wouldn't push it that far because I think you are playing with fire over 500whp on a single walbro.
Your best bet is to either run duals in parallel or run another nice pump inline like a 44. I still wouldn't be surpised if the 255+B044 still runs out before the 1000s, however it will support the horsepower range you are talking about safely.
