Stock Fuel Pump Limit? - Page 2 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

We can confirm everything Fastlane is saying. The dual fuel pump units are a must at these power levels and the dual will easily take you well past the torque rating for the stock rods!!!

DOn't forget, its not the air/fuel ratios you are worried about on the dyno tunes. Its the rail pressure at the injectors that is important. Just because the AFR is good on the dyno, doesn't mean that the trims won't go lean on a nice long pull on the freeway racing another car on the top end after the PSI drops to the low 30s or worse. A dyno (unless eddy-current) is not 100% true to load anyway.

Just my two cents.....

What impact does a BAP have on the stock fuel pump. For someone that is looking to keep my car for a long time (10 years hopefully) does the BAP reduce the useful life of the stock pump? I am looking to get to 600-650RWHP on my LS3 with a CAM and a Centri S/C so at least a BAP is in my future.

Turbonetics kit will be put on very soon. They are trying to get it done ASAP.

We saw no pressure drop with a KB BOP at 635RW (6SP)
Now thats no to say once we add the 85lbers the rail psi wont go away quickly.

Our 2400HP Dynocom can be run as a eddy currant too

Fastlane and Stillen r u saying u saw the psi drop with a bop/stock pump or just with the stock pump?

Just curious as to what u guys are seeing
