What does the standard B16 Honda fuel pump flow, not talking what power it supports just flow.
I understand running a direct power feed to the battery (relay in line) will aid efficiency a little, Honda have over engineered everything else so what about the fuel pump.
I have tried to find the answer but to no avail, anyone?

 

not sure on the flwo rate but generally a stock fuel pump is good for about 8 psi of boost with moderate turbo. They just dont cut it when it comes to flow. Now if your trying to do somehting like leave the stock fuel pump in place and then run an inline walbro or bosch 044 then that will work jjust fine and will give a little help to the inline pump

 

I’m not implying I’m going to try this but it certainly makes interesting reading

Again, not disputing your real world experience but it would seem quite a few people have run the standard fuel pump beyond 8psi with a reasonable size turbo and experienced no problems.

Me personally, I just not sure it’s worth the risk for the price of a after market pump but I’m curious to know what the OE pump actually flows.
