Hi did some searching on here but wasn't lucky. We'll anyways I'm working on my new setup and wanted to know if the walbro 400lph with id2000 be able to run them ok or will I need a bigger pump. Looking to reach 700 hp
Race gas will be used. Also may use the full blown with 255 -8 k -6 return

 

Depend on the type of fuel maybe with race gas, and upgrade wire to get a little more juice out the pump, but if e85 from what I was told! No! The walbro 400 won't do it. Either go bigger with an aeromotive, add an extra inline pump, or go dual.

 

Yea I'll be using race gas c16 or rocket fuel brand whichever we can get ahold of

 

Well, I don't have the graph in front of me showing what the pump flows exactly at different voltages and you didn't specify a fuel pressure, but you can look at it like this:

400lph is 400,000cc/hr or 6667cc/min.

4x2000cc injectors would need the pump to supply 8000cc/min at 100% duty cycle.

It could still be enough for your power goals, but it looks like the injectors will outflow the pump.
