    This was at the PRI show in Indy, being OD it will make the SC spin faster which should increase boost, I will call ATI Friday for more info.

    We don't know that yet, but this will be a very easy item to put on and test, I have two friends that are at pri and are dealers for ATI that are going to place an order and get more information today.

    The OD dampener won't effect the blower pulley assembly, but should spin it faster making more boost, how the electronics handle that ? Only one way to find out,LOL My cat is in storage somewhere like quite a few here......

    I bet you could add a lbs or two with the stock tune. I expect the stock tune to be pig rich...

    The OE dampener is rated too 13,000 RPM's and the car was NHRA certified with it on. Why would you change it?
    I personally don't see a benifit to changing it.

    I was under the impression that you want a smaller blower pulley, not larger...

    I don't believe this is true. It's just a one-way mechanism, no clutches involved. Can someone confirm?
