Do you really need a 255 Fuel Pump with 5psi of Boost?
I have a Drag 4 Kit installed on a 94 Accord. I wanted to know with 5PSI of Boost do I really need to have a 255 Fuel Pump.
The Walbro intank Fuel Pump is very loud.

It's not "will the pump do for only 5psi", it's "can I keep myself from turning up the boost" you need to really be asking.
Besides, don't DRAG kits use FMU's? 150psi @ rail + stock pump = bad bad things

abeaujuin, if you will ever run over 50psi line pressur eat any time for any reason, then, and only then do you need a 255lph. The only - I repeat - only difference in a 190lph pump and a 255lph pump are the flow rates over 50psig.

what kind of math are you doing?
5psi x 12 + 38 + 10 = 108 not 150+
