injector sizing

[Bruce Bowling]

~ Hi.  I'm new to the EFI list.  Excuse me if these questions
~ are exhausted:
~ 
~ I have a '84 928S with L-Jetronic.  I'm interested in increasing
~ performance, but my budget will allow only one step at a time.
~ 
~ Before I add a hot cam, can I oversize my injectors without
~ any negative effects?  I think stock is 19 lb/hr, and I'd like
~ 25 - 30 lb/hr.  I would think that open-loop mode would run
~ too rich; if I'm right, can it be adjusted on L-Jet?
~ 
You may be able to screw with the supply pressure.  The 
square root of the ratio of the fuel pressures equals the
ratio of the injector flows.
