So are the new ones any better? Do they pick up more power? More underdrive? Is the outer ring made out of steel still? Why is is SFI approved? Thanks.

What problems did the old style have because I have the old one and no problems so far. The only thing that I didnt like was the outer ring was made of steel and now its got the rusty look. Whats different about the new outer ring design? Thanks.

Are all the new ones SFI approved? If they are they should have a SFI sticker on them.

How does a crank pulley cause knock retard? Has that been eliminated with the new pulleys and if so, how was that achieved? Last but not least, should I remove my older one and replace it with the SFI one? Would it make any difference because I think that I am getting the knock retard. Thanks.
