i've never been able to find much info about them, think you might have to sleep with a Bosch agent to get anything of much use
dunno if this helps
Bosch 2 spring
(assembly number 0432193879)
nozzle size/type - DSLA 145P208
nozzle holder - KBEL 98 P52
initial pressure 200 atms
secondary pressure 280 atms
I like your thinking, in theroy it should work in the same way as the vdub lumps but theres only one way to find out
