At 70psi and 13.5 volts, this Siemens pump will supply about 62 gph which is about enough fuel to fully support 60# injectors at 25 psi boost and 100% dc.
At a more reasonable 85% dc, it's enough to supply 70# injectors, roughly.
This pump is about 6 gph more than a W340/00169 and 4 gph more than a Supra pump under those same conditions.
But it's still about 10 gph less than the $500 Apexi BNR 32/33 Skyline pump, so if you're looking for the "best" in-tank pump (unless you include the Jay Racing Pro-series 044 or $450 Bosch motorsports 413 external pumps mounted in-tank which flow about the same as the Apexi).....
