It's not that it makes noticeable hp but that it helps keep your ps pump from burning up on track. And yes, you need a new belt that is proper sizing. Did this on my Spec Boxster. Let me know if y'all want to see before and after pics.

We use them on all our race cars. My no BS .02 is way over kill for a street car. What they don't tell you is most (no idea about this pulley) under drive pulleys require you to cut down the TDC boss. Its not a big deal but something you should know about.

what is a TDC boss?
how much extra hp/torque do they give you... is it more on top end...?
