Yeah I know this has been beat to death, but here's the reason for the pole. People who have problems with these will tend to speak up, and people who don't tend to be the "silent majority". Because of this, the data gets skewed; it's hard to tell what's really going on. (Of course I'm assuming I'll get an even cross-section of respondents doesn't it...)

So, preface the pole with the assumption you have a lightweight crankpulley and you run the engine below redline. I feel running higher than redline introduces too many other variables, making the pole useless, so please only reply if you "play nice" with your motor.

i lightned my stock one,and so far,no problems...had it for about 40k or so.Key there...i only machined off the power steering pulley section,and left the alternator section with the rubber ring.

 

Which motor we playing with? Long stroke D16 motors need the dampener. Short stroke B motors can get away without the dampener.

 

I've had a UR underdrive crank pulley on the motor for the 3k miles that I have driven it. I dont notice any "problems" per se, but I have nothing to compare it to either as far as performance. It's pretty to say the least

 

Early D16's (91 & earlier) have a solid pulley, no damper. The damping mechanism is built into the design of the oil pump gears.
