Default NNBS fuel system revisited

I just read over at camaro5 that some shop pushed 833rwhp through a stock camaro fuel pump and BAP but that was right at the limit.

Im wondering if anyone tried pushing the stock NNBS pump (with FPCM) + a BAP.

Would this be enough for 800bhp?

I think it can be done with a BAP. The Camaro has the same FPCM as a Silverado. I think it will work!

smokeshow said he maxed at about 700bhp without a BAP with fuel pressuring dropping alot.

I will stop modding at the ballpark of 800bhp if I could get away with not requiring a fuel system.

the pumps and FPCM on the camaro are a little different, not sure if my truck is a flexfuel either because the flexfuel pumps flow even more. Also pump duty cycle could be increased based on RPM in the tune, not sure if anyone tried this??
