Message	I had an NA with 153,000 and an underdrive pulley (with no harmonic dampener) and spun a rod bearing, now I'm not going to blame it on the pulley for sure BUT the amount of power you make with a UR pulley is very little and not worth possibly shortening the life of your bearings. If you do get a UR pulley get the one with a harmonic dampener at least, it's not just on there for comfort- it's to absorb the shock of damaging vibrations in the motor.
