Electric Fuel Pumps

[PxTx]

So how fast or how much hp car a duplex pump handle vs a "Pro-Stock" triplex?

I've read that a single pump is good for about 250 hp. I know the special pulse damper on the discharge line helps to even out the pulses and is good for about a 30% increase in flow. I am speculating that singles are good for 250hp, the duplex is good for 500 hp and the triplex is good for 750hp. Rather than trust my speculation, I would love to know what people have actually done with these.
