Not going to start an arguement about the N1 crank pulley, i mean i run one myself.....!!!
But yes it was developed by honda, but for the B16B engine. Difference being that the B16B is a very tough engine with a great rod length to stroke ratio hence it's reliable high revving ability. this impacts less forces on the cylinder walls and in turn reduces engine vibrations at high revs especially
4 pot engine's are not the most balanced engines, take a straight 6 for example, straight 6's have both primary and secondary mechanical engine balance and thus have much less engine vibration than engines which have fewer cylinders
I looked into it myself and it seems that the major damage is from folk using cheap alloy pulleys which wear about the woodruff key and vibrate themselves to death. However i know how much Endyn and blueprint racing are adamant on using a good quality harmonic dampener on all their engine builds
Food for thought really, as i say i use a N1 pulley on my 1600, but for peace of mind will be using an aftermarket dampener on my new 1800 build
can you recommend a good one?
