I know there is debate on whether to change your crank pully.I knowan underdivencrank pully isn't good, but what about just a size difference?What are the advantages and disavantages and should I get one?

 

dont even waste your money, i just finaly got mine off because the bolt stuck in tehre and NOTHING would take it off. I didnt even see a difference in power

 

you can get power gains in more logical ways

 

Ya, Im not sure what all the hype is about these things, I guess its cause they look nice.

 

but the size change is what makes it an underdrive pulley....

they also weigh a lot less

 

and are fine to use if you DO NOT have a harmonic balancer built into your original.

 

i felt some power gains in mine. not lots but a little. and ya is does look nice, the difference in wieght when i held them both was huge.

 

If you really want to get rid of your stock pulley just put on a lighter billet aluminum one that's the same size. That will reduce the rotational weight a little and give you a small power gain, but there are better things to invest you money in.

 

I think thats the main thing that I heard about using all 3 pulleys. But I also read I believe in a performance book that honda engines are built in a way that it wont effect your engine's balancer and ruining it in a short span of time.

 

Did you only have one pulley in? I heard it's useless unless you get all three.
