Walbro 400lph Pump, 1000cc injectors, Stock FPR enough for 600whp on pump/race gas?

Hey guys,

I did a lot of research and just wanted some confirmation on my fueling setup.

I'm a bit on a budget right now and can tune around an overwhelmed stock FPR and too much pressure on idle. Not too concerned about that...
Is the 400lph enough to hit my goal of ~600whp? My calculations say it's a stretch, but doable. Of course, I will wire it via a relay directly to the battery.

I can upgrade next year to an even bigger pump or dual pumps + a quality AFPR and bigger lines to hit 7-800hp, but the Walbro 400 would only cost a 100$ and I could sell it to a buddy, when I'm done with it.
Just don't want to blow up my new built engine with a 20 year old stock pump...

Thank you!

even though you didn't give any info on your motor - yes more than enough, on a 2.5L you should be around 55% IDC by 7500 RPM
