does anyone know anything about the bosch k-jetronic mechanical injection system?
ive done a good bit of reading:
http://www.users.bigpond.com/INTERJECT/KJETRON.HTM
http://www.auto-solve.com/mech_inj.htm
and apart from running stupidly high fuel pressures (!!) i cant find any specific info on the injectors themselves (though one critical thing i read was that they are internally valved to open at about 3.3bar)
does anyone have any info on bosch mech inj part numbers, or approx flow rates @ standardised pressures? i have a couple of different types here from bmw and merc and am scheming something to do with them 
cheers

I only know the very basics too - it's sort of like a low pressure ripoff of a diesel system, kinda. Anything you do find, please share!

I just learnt about this injection system at melbourne , it was used on the BMW M10 engine.
Basically it was a kind of constant ( k = konstant lawl ) injection , ie the injectors were flowing even when the valves were shut , that is how they made power , lots of fuel , lots of air , but the downside is , most systems like this will not pass emissions laws.
BMW used this system back in the day when no-one cared about emissions.
