Pros (that I've noticed):
Engine seems more responsive
Less weight
Less belts to change
Cons (again, that I've noticed):
No aircon
No power steering
all are ok but please add to the cons :
-oil pump failure need to check/replace often.
-it's a must to use an oil pressure gauge
I'll add to that,
Any solid crank pulley is bad news. I'm not going to go into detail why but the long but short is that it doesnt dampen crankshaft harmonic's. As well as the reason above, you'll also experience accelarated main bearing wear.

Nope!
With regards to the oil pump,people like to blame something when it all goes wrong, i know a guy running a N1 on his turbo civic for around 30k with no issues whatsoever.
Does anyone balance a clutch when they install one?? Thought not!! This is a greater rotating mass giving off far more centrifugal vibration at high RPM than an unbalanced pulley, plus the N1 is balanced from Honda and to double check I had mine checked and balanced to 9800 rpm and was near perfect
On the standard pulley you have more weight overhanging the end of the crankshaft resulting in higher stress levels on the crankshaft, with all the research i've done i believe this is why the standard pulley runs the harmonic damper and the N1 doesn't.
The standard pulley has to run 2 other belts from factory, if one of the pulleys on either the P/S or A/C was to buckle or a bearing die, this would create centrifugal instability and this is where the harmonic damper would come into effect.
theres a lot of people who like to have there 2 pence worth who have no real first hand experience with the situation, thats what i've discovered. it's like they have seen a thread on civiclife.net about a guy who's oil pump failed after fitting an N1 pulley, so this automatically means there bad, then everyone jumps on the bad wagon, not considering all the other factors of why the failure could have happened
the same can happen if you use stiffer/solid engine mounts ?
if oem damper can be affected from the extra vibrations ?
we don't use harmonic dampers on jet engines which spin at 40,000 rpm + which internally are very similar, everything is just balanced to perfection!
explain the clutch balancing issue?? physics will state that this will have more of a detrimental effect!
why would honda fit them to RB EK9's if the have detrimental effects? im sure honda did there research

What are the critical speeds for the jet engines? How often does the engine pass through them in normal operation?
I don't get the internally similar bit. To a piston engine?
