it's the thickness of the wire that is used to wire the fuel pump.

Re: honda fuel pumps
 

and why it's able to suplier enought gas for more power just with a thicker wire? ive seen if you connect the fuel pump directly to battery..getting lil improve on it...but...

Walter, walter, walter........ Study electronics, and you'll understand how wires affect current ;)

DSM centric, but it'll open your eyes to how voltage supplied to a pump effects flow rates. I'm always suprised that more Honda people don't re-wire their pumps.

cool info, ill read them when i return of my work...

mike.. ill do :1

Re: honda fuel pumps
 

Yeah, it is interesting. A LOT of other car guys praise this very early on in a build. Without even thinking, dsms, supras, 3Ss, and that's just from cars i've owned or my buddies have owned.

Re: honda fuel pumps
 

this is a little late, but most stock pumps can supply fairly big injectors as long as you keep the stock fuel pressure, remember, pressure=restriction to flow, it does mean more flow, it means less. bump the pressure and you loose flow to the injectors.

Re: honda fuel pumps
 

False, increased pressure to the injectors MEANS MORE flow. Period.

The problem is that when you increase the pressure, the pump can't flow enough at the increased pressure.


It works the same in turbochargers. Raise the pressure and you will get to a point were the turbo can't flow enough at the pressure you want.

i think that happen with Airflow..

yes that's true, increased pressure does mean increase flow at the injector, but i was referring to a law of fluid dynamics, increased pressure=restriction to flow, and of course this is true, because we have a fuel pressure regulator on the return side of the fuel rail, sorry should have been more specefic. But you did say what was i getting at "the pump can't flow enough at the increased pressure" because as pressure increases flow decreases, it takes a bigger pump to flow at higher pressures.
