Thought this might have been covered, but I'm an idiot when it comes to using the search feature effectively.

Anyone have answers for the following:

Flow rate for the stock fuel injectors
Expected maximum duty cycle (usually less than 80%, not sure what we've got..)
(edit)
Fuel injectors, B207R
Type Siemens, colour green
Style 2 hole
Resistance 12 ohm
Flow capacity ml/30s 176 +/-7
Maximum permitted difference between injectors ml/30s 14
Can anyone verify the maximum duty cycle for the injector?

Static pressure @ fuel rail (fuel pump capability)

Thanks in advance

The pressure regulator is a diaphragm-controlled overflow valve set for 3.0 bar.

So the pressure in the fuel rail is kept constant at 3.0 bar. Excess fuel is released via the overflow valve back into the fuel tank.

Hope that helps!
