Power expectations from 346ci Forged LS1 + 76mm Rear Mount?
I know bench racing is dumb, but I'd like a rough idea of what I will be expecting with this set-up on my car...
Fuel:
Dual Walbro 255's
-6AN Feed from the tank going to a Aeromotive A-1000 FPR 1:1 Rising Rate
-A-1000 FPR feeds to Stock Rails and the FPR has a -6AN return back to tank.
-Seimens 80lb
Turbo:
76mm Rear Mount Turbo Triple Ballbearing Oil-Less
T4
0.96 A/R
3.5" Mandrel Downpipe (2 feet long)
2.5" Y-pipe going to Turbo (2.5" from Engine to T4 Flange)
Billet Wheel
1.5" primaries on Sanderson block hugger headers with 2.5'' collectors...
Large FMIC air/air with 2.5" Intercooler pipe
Engine:
346ci LS1
JE Forged Pistons 10.8:1 Compression + ARP Hardware
OE GM LS1 Headgaskets
TSP PRC 5.3 Stage "2.5" Heads + ARP Head bolts
*** 93 octane ***
LS6 Intake
227/223 .614/.610 115LSA
T56 - 3.27 gears...
Is 500rwhp going to be possible on 5-6psi?
Can I make 650rwhp safely?
What are my limits?
Thanks guys!

THere is an E85 Station LITERALLY 2 minutes from my house... what fuel pump do I need to go with that can support 650-700rwhp on E85? What will 80lb injector limits be?

At the same power level, you need about 30% more fuel when running E85 over 93octane.
From what i have seen though, plenty of people are making over 500whp on a single walbro with a hotwire kit and FPR, so adding a second pump with 80lb'ers should get you into the 700s no problem.
