Racetronix RX-F99 Fuel pump ok for Vortech V9 G? Sorry, I'm not sure if this belongs in the Fuel section or the Forced Induction section. I'm thinking Fuel. 
I have a used Vortech V9 Kit that didn't come with the fuel pump.
Looking at the instruction manual, the Vortech kit comes with a Trex pump (Vortech PN 4GK101-001 / 8F001-500).
The specs for this pump are here.
Rated at 40gph (151 LPH) @ 90PSIG . A chart for the pump is available here
According to the chart, at 58-60 psi, the flow is .84 -.88 gpm.
Multiply that by 60 to get GPH = 50.4GPH (189LPH) - 52.8 GPH (200LPH).
The kit is supposed to be installed on a stock F body, with the supplied / upgraded 38# injectors.
The Vortech pump is supposed to be installed in series with the stock pump (see attached pics).
I don't really get how this works with the stock lower volume pump and regulator in the tank placed before this inline pump. Does it let the normal fuel flow through it then when boost kicks in, the relay activates the inline added pump and the higher pressure kicks in?
I have a brand new Racetronix RX-F99-FPA fuel pump assy and RX-F99-FPWHG-2 Plug & play power harness (with boost a pump optional plug) that I purchased years ago, still in it's packaging.
The kit shown in this link
According to Lingenfelter, here, the kit is rated for 235L/Hr (62GPH) at 58PSI . Tests in the field have proven the Racetronix F99+ system will support upwards of 600RWHP and 700RWTQ in some applications.
Am I incorrect in believing that just the racetronix kit (with hot-wire kit installed) would be sufficient?
Do I also need a boost a pump, such as Kenne Bell Boost A Pump - 40Amp - KB89069 Supercharged - Street Version?
Would I still need an additional pump, such as a Trex, in series?
Thanks,
David
