I got new parts for my fuel system:

# Sard top feed fuel rail
# Sard 800cc high impedance injectors
(got a jdm 2jz with no resistor pack)
# twin GS341 255lt/h HP Walbro pumps

Fuel lines :
----------------------------------------------------------
# Custom fuel tank hanger with one -AN8 feed line till the firewall....
# Then goes an -8AN inline 'Earls' high performance fuel filter...
# After the fuel filter goes a ' Y ' splitter (-8AN inlet ----> Two -6AN outlets) for
the two -AN6 feed lines for the fuel rail.
# From the fuel rail goes a -6AN line to the Aeromotive FPR
# And last,from a -6AN port on the AFPR goes the stock (low pressure) return
line back to the fuel tank.

My question is: Will this system support 600 whp on pump gas...and
700+ whp on race (C16) gas?

Things I could change over my fuel setup if I have to:
Two 260 lt/h Sard (intank pumps) instead of two walbros...
-10AN feed line from the tank to the Y splitter instead of -8AN feed line

Please post your experience or comments on that fuel setup...
Thank you

Good to hear that....and good luck on your setup!
You are going to send one -8AN feed line from the fuel tank to
the firewall and then with a Y fitting split two -6AN lines to the rail like me?

Don't trust those Walbro pumps better go for 2 OEM pumps or 2 Bosch 044.

You'll get all fuel you need. Walbors will work, lots of guys use them on 1000hp+ but it's not the best. I went with the denso's and never had a problem. I would also run a new thicker gauge wire to feed those pumps.

The walbros will work no problem. There's a lot of speculation but IMO it's a lot of internet tuners repeating what they read. As long as you have a fuel pressure gauge (and you keep an eye on it) I would have no worries. If one fails, big whoop it's $100 for another.

BTW my stock denso failed at only 70k mi and I can't imagine spending $500 on 2 pumps when I could just spend $200 on twin walbros. Just food for thought.
