Stock pump vs bigger injectors??
Monday, March 28, 2005 6:33 PM
I have a turbo ecotec and my expectations now ..would like to get about 175 hp out of it with this project. my fuel set up will consist of 310cc gmsc injectors with a cartech FMU #2025 and a Accel AFPR set at 35 psi idle pressure and around 45 PSI set at atmospheric (sp) and i plan on using a wideband for above 0+ (boost) to see what to turn up or down on the FMU....now i know my stock fuel pump maxs out at 85 PSI...i plan on running 6.5-7PSI on my T3..so i might not exceed that limit..most likly

Has anyone ran a fuel setup similair with there stock pump? i was wondering if i will lean out because of my pump or ill be fine becuase of the bigger injectors..when i drive it with the wideband i know thats when ill know for sure..but what do you guys think or maybe experience? Kinda gives me a heads up...
Thanks in advance!

your stock pump maxes out realisticly at 65psi

and if your gonna be running 7psi on a t3 you will probley go over 200whp so i would watch it, but the stock pump is good for about that much but thats it


you should be fine with them injectors
