SleeperZ Posted May 28, 2003 Share Posted May 28, 2003 It depends on your application. You need to figure out how much power you will be making at what boost pressure. Add the boost pressure to your base fuel pressure, and see how much flow you get at that pressure. That flow better be more than enough to make the power you want - if not, look for another pump.

[/quote'] In a nutshell, you will need both. It took me a while, but I found a discussion we had on this a few months back: Fuel Pump Discussion Quote Link to comment Share on other sites More sharing options...
