Default Fueling for my procharger

Hey everyone, I bought a used p1sc 8 rib kit from someone local and im unsure on what i should do for fueling. my mods are...
ported/slightly milled ls6 heads
blower cam (which i was thinking of buying through brute speed)
SBE ls1 (01 ss)
TEA stage 2 ls6 heads
and obv the p1sc

im looking to make 12-14lbs of boost on this setup and looking to run e85. this car will be daily driven and im looking for good injectors, i just dont know what size to go with. and as far as a fuel pump goes, how much can the stock fuel pump handle with a Boost a Pump? also what kind of power do you think i can make on this setup? thanks in advance

80's and twin 340's is where I would start. I'm not 100% sure 80's will be enough for e85 though.

I'm hearing you can run a stock fuel pump with a BAP and make over 600hp, can anyone confirm this?

Nooooo! I wouldn't try that. I personally bought 60# injectors and turned out to be way to small. I'm not even running E85!

Look into something bigger than 80's and at least dual 340 pumps.

from what im seeing most people are running 80lbs or larger, but my main concern is what are the limitations of the stock fuel pump in a 01 ss with a BAP?

FIC 127's with twin 255's intank here with a maxxed P1 (600 RWHP) on E85. Consider twin 340's for room to grow.

Cammed Ls2, custom return system 8 AN feed and stock rails. I am going to upgrade to aftermarket rails since the distribution isn't the best with 600 and E85. Kind of pushing 800 plus through stock rails when considering the extra fuel flow.

I have twin 340s and I wish I would have just stepped up and done the twin 450s. If I were you, I would do it once and be done. I regret not doing a big fuel system the first time.

Those injectors have the USCAR connectors, for an LS1/LS6 engine the long style injectors with EV1 connectors are what you want to go with.

Do you have a forged bottom end in your engine? Bob

10lbs, but remember HP is what you need to be concerned with. More specifically, crank HP since the P1 will eat up 75-100HP that you will never see at the wheels. I wish someone with street driven twin 450's would come in here. I want to go that route but I am nervous that the 450 would put too much heat into the system just putting around.

Not sure how long the stock bottom end will survive at 12 to 14 psi, but the E85 will certainly help. I'd go with 100lb injectors, look for long style EV1. I'd go with a Walbro E85 Fuel Pump - High Performance 450LPH. Bob

12 to 14 psi with a combination like yours would be max for a P-1SC. Bob
