Hi William,

Just to put the record straight the only injectors that that have the flow
rate specificed in g/min and g/1000 hube are the injectors that you have
picked i.e.
 0 280 150 600 to 0 280 150 608, all the rest (injector part Nos 0 280 150
010 to  ... 985) have all got their respective flow rates in cm^3/min and
cm^3/1000 hube. The only other injectors that have their dynamic flow rate
in mm^3/hube are 0 280 150 001 to .... 009.

Nominal fuel pressure is not 2.5 bar in all cases, the fuel pressure is
specified in kPa.

I hope this helps. 

Before everybody swamps me Email about putting the specs up on the net, I
don't thing Bosch will be too happy with me.

If you have a part no that you are trying to find the flow rate for, Email
me i'll try and help as much as possible.
