How many of you have installed one?

I've read that some (maybe all?) of the pulleys available for the 987.1 requires that one shaves off a small nub on the engine block (it's a raised protrusion that is hollow and has a notch for a TDC lock)... is this the case with all of the upgraded underdrive pulleys? If not, which are designed to avoid this surgical procedure?

Thanks in advance.

The short answer is yes you have to grind off the boss. I suggest you search on this topic. There are a ton of posts. May even be a how to do it article. I did it on my 07 CS many moons ago and it was pretty easy.
