    I have been doing some research on failing crank pulleys and Im curious as to what mileage people are changing them at. Im at 38k now, is this something I should be doing soon? Thoughts on best replacement?

    I replaced mine at 10k and again at 12k. My OEM crank pulley failed...to make the car go fast enough.

    I'm curious as well. I'm also curious if or how much sooner they will fail with Stage 2.

    I'm wondering too. I want to go JHM crank pulley with stock pulley and be done with it. That should equal stage 2 right?

    What happens when it fails and how catastrophic is it? no damage just can't drive or potential internal engine damage?

    You'll have no accessories, main one being water pump.. You'll overheat if you keep driving it.

    Heard of it taking out other things in the bay but I was lucky. So yea it can get pretty bad.

    I'm at 40 k with Stage 2 for just about 3 k of those on a 2013.

    I figured I had lots of time before I needed to worry about this as it really doesn't seem that common, and mostly on older, higher mileage cars.
