Here are some flow numbers for the walbro’s, [http://www.roadraceengineering.com/fuelpumpflowrates.htm](http://www.roadraceengineering.com/fuelpumpflowrates.htm) The Walbro “255” LPH will supply enough fuel for 4x950cc/min injectors that are maxed out at a fuel pressure of 58psi, which would be good for about 625 crank horsepower on a 4cyl. At 73 psi fuel pressure this pump is only good for 575 crank horsepower. Where as the Walbro “255” HP will supply enough fuel for 4x1000cc/min injectors that are maxed out at a fuel pressure of 58psi, which would be good for about 675 crank horsepower on a 4 cyl. At 73 psi fuel pressure this pump is good for 700 crank horsepower. These numbers are based on calculations not real world numbers. --- _[View the full topic](https://forums.speedlife.net/t/fs-parts-lots-of-stuff-updated-july-20th/25897)._
