Stock Fuel Pump Limit?
Hey guys,
Been searching high and low and getting many different mixed answers. My question is: What is the Horsepower limit of the stock fuel pump? How much can it handle until you have to go for a duel in-tank pump? Also how much can it handle with a Kenne Bell BAP installed? I know i got to changed the injectors before the pump, already got that down. Just want to know about the pump Stock Pump Limit: ? Stock Pump w/ BAP Limit:? Thanks, Sam |

My L99 quit making power at 528rwhp with a procharger and boost a pump. Got a dual pump from FASTLANE and went to 573.

our dual pump will support 700rwhp safely and 750 with some big injectors to compensate for pressure drop. our new triple pump system will support 1000 rwhp.We have dynoed it at 940rwhp and still had 47 psi. |

Soon as we hit 550 hp during dyno tuning, my ls3 fuel pressure fell to 35 psi. Maggie 2300, headers, exhaust and cai.
