    FYI; I installed my Dinan CAI nine months after the Turner Power Pulleys and didn't see the dramatic change I did with the Power Pulleys. The sound and look is great but, little change in the performance.

    Great info, thanks Costco! I in fact live very close to a Costco myself haha
    In and of itself, nothing. But, it's like the pulley idea, less strain on the system - lighter, more free flowing. Maybe more similar to the mechanical fan delete which I did too.

    I don't like the thought of underdriving the electrical system (alternator). I doubt anyone has done any studies on the long term effects of underdrive pulleys and its effect on the electrical system...

    I wouldn't worry about it. The alternator was designed to put out ample current in any scenario the car might encounter plus a buffer to account for variances and or an alternator getting near the end of it's life. And it's designed to do this at idle.

    It's the same with underdriving the water pump. In it's stock configuration our cars could idle all day long in the middle of summer with the air conditioning on and not self destruct. With pulleys maybe it can no longer do that but as long as you're paying attention it shouldn't pose a problem.

    I have the turner set. Don't go installing these thinking huge changes, but I did notice a change. And would I do it again? Yeah, probably would. Car feels "peppier" to me with them on.

    It's all about the steering feel. I dont care about anything else that you may or may not gain...the thing that was most noticeable on both of my BMWs was the difference in slow speed steering feel.

    What exactly do you mean by slower steering feel? The ratio doesn't change, so what is it that feels different? Less power assist?

    When the revs are low and the steering input is high. The feel is heavier and you get a meaningful response from the road surface.

    Noob question! I got the TMS pulley kit which I'm going to install tomorrow, I also picked up an idler pulley and the alternator tensioner roller as well. I figured, since I was in there... Question is, since the pulleys are going to want to spin, do you loosen up all the pulley nuts while the belt is still on and tensioned? Or is there a special trick? Also, are they all threaded standard? I looked around for some DIY's but didn't come up with anything good.
