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.

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.

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.

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.

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.
