I ahve a low pressure 255lph Walbro intank pump. I plan to run around 600rwhp. If this pump isnt enough, I could add a 255lph inline as well. Will this be an improvement, or will it not really do anything since both pumps are rated the same?

 

I am assuming you want to run an inline to increase fuel pressure through your lines? You may want to buy this instead of buying an inline pump.

Well, I have an intank Low Pressure Walbro pump already. Will that support 600rwhp? If not what are my options (cheapest possible)...

Thanks.

 

It should work. You might need a boost-a-pump. Jack at Racetronix has the best answers on this issue, IMO... I'm sure he'll chime in soon.

 

So when you say boost a pump, you mean an inline pump?

 

No, it's a box by MSD that increases voltage to the pump under load to spin it faster and thus increase both volume and pressure. Jack could explain it better, I'm just regurgitating here... I think it's around $300. There is some question whether adding an inline pump helps or hurts the flow. I'd like to hear more discussion on this, but a search would probably turn a lot up.

 

Also I believe Kenne Belle offers a boost a pump.

 

Ok guys. Good input. Lets keep this one floating around so others could chime in. Again, thanks for the help.
