I have a GT500 what else would I need to sustain 700rwhp most reliably?

Dual BAP (you already have twin pumps) and either 60# injectors or slightly larger. I have no idea how much HP a 60# injector will flow. I'm thinking 60 would be maybe enough, but I would ask someone who knows.

I believe the fuel rails are plenty big enough too.

Depends of what you going to do with your 700 rear wheel. If car is going to be a track king rather than a dynoqueen, having enough fuel is NOT enough.

I don't pay much attention to rwhp numbers, so not really sure at what point we moved from the GT500 duals (with 2 single BAPS) and 60 lb inj, to the Fore Precision triple pumps and 80 pounders. Maybe around 650-700?????? Fuel rails were upgraded along the way. Got to watch for them dyno numbers though...650 on one machine can be 750+ on another...lol. My tuner uses a real tight mustangdyno, so even if I knew the numbers..may be misleading. With new build, moved to a return-style fuel cell (don't know much about it).

Just if the car is going to be raced on a prepped surface with violent launches and high boost etc...be generous with the fuel

I like the idea of the Fore presicion triple hat. When I did my fuel system the triple hat was not available. Kenne Bell had done some testing on the stock fuel rail and gotten itno the upp 600's I believe. Sometimes when getting the bigger, longer injectors, it's beneficial to get a larger/different fuel rail for fitment of the injectors. I had difficulty getting my fuel rails to work with the attachements KB provided. Had to change them slightly.

If i were to do it again, I may get the triple hat, but I would weigh the costs and benefits of both.

Definitely a dual bap with the gt500's to be safe. Bigger injectors as suggested as well.
I'm using 75# injectors and GT500 pumps with CPR fuel rails, and fuel pump duty cycle will get up to 80%, and that's with somewhere around 550-575 rwhp w/automatic.
