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 and 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 engines.
They need to use a regulator that increases pressure as the 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 the main 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).
    .42 BSFC - Race Engine
    .47 BSFC - Hi Performance Engine
    .52 BSFC - Stock or with Light Modifications Engine
    .57 BSFC - Supercharged / Turbo Charged Engine
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 have come from various magazines, web sites, and manufactures catalogs.
