I was wandering how good the mechanical pump really is. Cause I'm shooting to go with 140hp injectors, full cut dv and would like to get to maybe 24* timing eventually. I have a 0# fuel plate all the way forwards. 4k gsk 60lbs which will be upgraded soon to 110. But how much fuel will the stock pump fuel me up to. Stock timing at this point in time. But wod I need a better pump after I got injectors or injectors and dv or possibly with just added timing. Srry if I'm so confusing but thanks for help if u can

 

The stock lift pump isn't to bad it'll fuel enough for 500ish+ if it is in good shape. Best thing to do would be to put a gauge on it and see.

 

What's a good pressure number outta these mechanical pumps. If I remember correctly should be about 15. Please chime in if I'm wrong.

 

double that and you'll have ideal pressure, search TORK TEKNOLOGY. two articles have been released that will explain the stock lift pump, its efficiency and lack there of. as the articles are released he's going to discuss how and what it takes to increase the stock pumps effiency. He also has developed some superior to factory designed over flow valves. he has multiple designs for multiple configurations. he also claims anything above 31 psi (iirc) on the P1700 pump actually causes the IP efficiency to drop.
