Quick question: 550's and fuel pumps
Can I run my stock fuel pump when Im gonna be using 550's? Low boost is gonna be around 7 and 12 will be high--at the track on race gas.
Or, should I just buy a walbro intank? If so, the 255, or the 255 HP ?

Here is a graph of the 2000 civic si fuel pump for fuel and HP capability.
This is the flow of the pump only, and does not include the fuel pipes/ filter/fittings etc which impede flow. Subtract 20% from this number and you will have a reliable crank HP.
For example at 40 psi fuel pressure the pump will easily support 300 crank HP with your 550s
Of course you could always read our tech section http://www.hondata.com/tech.html and get all the information.
