what HP?

 

I know that a shop has a bolt-in intake fuel system in the works that will support up to 1000ish whp. Should be released soon & it is very quiet.

 

Any other opinions

^^ That says single walbro 255 setup good for 600+

 

You will be cutting it too close in my opinion. It may make it, but you are not leaving much headroom. A cheaper solution would be to add an external booster pump activated by a $25 hobbs switch at 20 PSI or so. I personally would not risk such an expensive build on cheaping out on fueling. A booster pump is about a hundred bucks and since it is boost activated you don't have to hear it screaming all the time like an external aeromotive pump.

 

it's two pumps. one in the tank and one in-line. it good for 600 + hp plus you get the antisurge tank. or you can go with the 1000 hp system.

Not sure why all this back & forth.
The BR dual pump set up works great. Its been used by many cars and you have never heard of any problems or issues from anyone that has used them or is using them.
Go with what works!

Question answered.

 

On one Walbro my fuel pressure started to nose over and AFRs started getting lean up top at 535whp. I stopped immediately and added the second pump in a Full Blown hanger

I was having the same probelm with ETS 35R and a fully ported head spraying meth at a mix of 50/50. Anyways the turbo was sucking the lines dry so I had to move up to twin pumps in the tank from BR. Works good. One pump is on all time and other one kicks on at 14 PSI I think or 19 PSI. I forget. Anyways I also have the Aeromotive regulators mounted in my engine compartment and they look nice. I also have their fuel rail. So far it works great. no complaints. Cost me around 800 installed for everything.

 

Ohh and I put down 546 HP and 400 ft lbs @ 29lbs

 

T67 P-Trim, 604/457, 27psi, 1 walboro 255, stock fuel pressure regulator. Only had that tune on for like a week, then went to more conservative 594/467 tune same single pump and stock FP reg.
