How much RWHP can you get from a single one of these pumps, factory feed line, returnless? Will have a wire upgrade too. And we can add a BAP to the mix if we need, too. And do you need a modified FPDM for safety there?

I plugged some assumptions into a cheat-sheet and I get 575RWHP with an Aeromotive 340 at 80% duty cycle. It would help if you provide NA RWHP and Boost pressure to check flow rate at boosted rail pressure.
Hopefully someone else can chime in with practical experience.

Regarding the FPDM, see this thread

My AEM's have done me well and are super quiet
I was looking at the charts for the two pumps and it looks like 700hp. dont know if that is rwhp or flywheel. that is at 60psi rail pressure for i figure 20psi we would run max.
i saw where zack said 550 on a single pump with wire upgrade.
is a 400lph pump too big for a returnless system? doesnt make much sense to me that it would be too big. as 2 255 pumps is 510 right?

The Walbro 400 is way too big for a returnless system, and will not work in that configuration.

After having a bad experience personally and several other mustang buddies with aero stealth' so don't recommend them. However I was chatting with the lead tuner of our local speed shop and he said the newer Stealths haven't had as many problems as they did when the first ones came out. But with such a huge price difference 165 vs 99 and only 20lph difference in flow. The AEM is a great pump.

Mine's been fine so far. I turned off my boost a pump. Not necessary anymore. I monitor my a/f gauge closely. I suppose I should sell it, but think I will leave it installed for future upgrades.

YES. You need a modified FPDM. I make those if you need one and you could also run two modified FPDMs if you want.

I love the smell of Nitromethane and rubber in the morning!
