They max out about 350-360bhp running with a base fuel pressure of 270kPa (2.7Bar) @100% DC
which puts them around 500-550cc/min mark @3Bar, by my calculations
Most havent bothered to flow test them, and they are a ford only part and info on them is very scarce,
and as Siemens 660cc/min injectors can be had cheaply most use them as a lot is known about them with plenty info on the tinterweb, allowing a very accurate Injector model to be programmed into the ecu.
