For non 1:1 gain rates you might want to ask around both www.cartech.com =
and www.powertrain.net for a couple of good examples of what's possible. =
Be wary of the ultimate injector operating pressures for your =
particular injectors & drivers. Also, be wary of your deliverable =
pumping volume at elevated pressures. Very high pressure AND flow are =
often hard to simultaneously realize without specific forethought.

Subject: Rising rate fuel pressure regulator
Scott Flanagan mentioned he was trying to map out a rising rate fuel =
pressure regulator.
I am also looking for a rising rate regulator that reacts to turbo =
boost.
All the turbo fuel pressure regulators I have seen, raise fuel =
pressure at a rate equal to the amount of boost.=20
I would like to find a fuel pressure regulator that gives something =
like 2 : 1 to give around 75 / 90 psi at 20 psi boost.
The aim is to bypass the need to fit larger injectors when increasing =
the power output of the engine and also the standard injectors will =
allow the car to idle better.
I also want to fit a fuel pressure sensor linked into the ECU to keep =
an eye on fuel pressure.
