Stan Weiss' fuel injector table  http://users.erols.com/srweiss/index.html

The flow rates shown are at 100% duty cycle (static) and are for gasoline.
Although we do show some rating pressure most injectors are designed to operate 36.25 PSI / 2.5 BAR or 43.5 PSI / 3 BAR - Chrysler and Porsche some times use 55 PSI / 3.7 BAR
Remember this is a pressure differential across the injector, this becomes important in Turbo/Supercharged (SC) engines, where you need to use a regulator that increases fuel pressure as boost increases.
Injectors are rated at "X" psi, but most will work and flow more fuel at a higher pressure.
There is a calculator on my Home Page to convert flow numbers from one fuel pressure differential to another.
Fuel pump flow decreases as the pressure goes higher, so make sure your fuel pump has enough flow at the pressure you raise it to.
Estimated Horsepower figures are calculated at 80% duty cycle and 95% duty cycle also based on BSFC (Brake Specific Fuel Consumption).
    .36 BSFC - Turbocharged Intercooled Diesel
    .38 BSFC - Turbocharged Non-Intercooled Diesel
    .42 BSFC - Race Engine or Older Diesel Engine *
    .47 BSFC - Hi Performance Engine *
    .52 BSFC - Modern Stock Engine or Light Modifications Engine *
    .57 BSFC - Supercharged (SC) / Turbocharged Non Intercooled Engine
    * - These include N/A engines or Supercharged/Turbocharged Intercooled Engines.
Electronic fuel injectors come in two types Low (1-5 ohms) and High (12-16 ohms) Resistance (Impedance). NOTE this can be measured between the 2 pins with a multi-meter.
Like with other engine parts Bigger is not always better.

These numbers were compiled from various magazines, web sites, and manufactures catalogs, and should only be used as a Guide. Always check with the Manufacturer.
 

In German language: Magnet ventile Bosch 0280150.pdf  The 32valve 928's have number 730 as injectors.
