i know im a new member here, but i've been visiting HT for a long time now and i always see threads on why the ctr n1 pulley should or should not be used. i myself think that dampening the crankshafts harmonics is important. i wont tell people what they should and what they shouldnt use, cause my motor is mine and your motor is yours and its our own personal descision. but i will say that for the people who whould like to use the ctr n1 pulley but are afraid to because the premature wear on bearings due to the lack of dampening should check out the Inlinefour N1 pulley @ inlinefour.com. they use a oem honda/acura crank pulley and machine and balance it to your specs.
ex.. (if you want to run just the alt. belt, or alt belt and p/s..etc..) or you can purchase one already done from them. i think they said that a b16 or gsr pulley after modifications w/only alt. belt (just like ctr n1) is about 3 lbs. i think its cool because you get the lightness of an after market pulley and the dampening affect of a oem piece. and just in case you are wondering, no i do not work for or at inlinefour.com. but i do plan on getting one of these pulleys myself.
