Oops have I over snipped? 8OD

According to that model engine book I mentioned a while ago
the miniature engines were actually cool running partly due
to the evaporation effect of the ether in the fuel mixtures.

Didn't we have a conversation somewhere before where I
postulated that at steady state cruisin' (excepting
damaged/worn out engines) the final efficiency is down to
the state of the injectors; namely the spray pattern and
break pressure. Didn't I also suggest that if we take Hagars
pump and injector set-up and transplant it into a less
efficient engine  (heart and lungs!!) The receiving engine
would become similarly efficient

This leads me to my current dilemma...I'm considering upping
my injector break pressures from 155bar.
Will this lead to better efficiency due to a finer spray?
What happens to the life of a pump when it has to hit the
fuel with that extra force. Camplate wear increase? Shaft
bearing wear increase. Timing belt strain?

Or does everything operate well within limits?
