Is my fuel pump large enough for boost?

[5.0 Hatch]

Last year I found myself in a bind and had to replace my fuel pump with whatever I was able to find. I installed an Airtex E2301M pump assembly. So far it's been flawless. However, now i'm looking to add a vortech and I'm unsure if the pump is enough. According to the specs, it's 70gph which translates to 265lph which I believe would be sufficient if accurate.

It also supposedly interchanges with Walbro TU229

I wish I would have pulled the part numbers off the pump itself before dropping it in but that ship has sailed. Is it possible to monitor fpdc N/A to determine if it is enough or not for boost? Or any other guidance that doesn't lead me to dropping the tank?

Monitoring FPDC right now wouldn't hurt. If it's already at 80% I'd say you need to upgrade. If it's 50-60% you have a little bit of room.

Thank you. I did a datalog and it's showing .40 at WOT. I believe this means 80%

If you're only running one pump then you don't double it.

Okay that makes sense. Yes only one pump. So at 40% at 300hp n/a, do you think it would support 450?

I think so. Just keep things conservative.

I ran out of pump at 450 using a DW300 which is supposed to be 340lph. I would not expect a 260 ish pump to carry 450hp.

You using the same injectors? Duty cycle would be irrelevant if not on the same size injectors.

A 255lph and boost a pump got me to 450w on my old 2V. I definitely needed the boost a pump. This was on 60lb injectors.
