Was your car N/A or Forced Induction when the pulley broke?

It was NA. His crankshaft was damaged, because when he went back to OEM it wobbled too. It actually shattered too.

..... do you know how many miles/km since installed?.

These problems may appear "in the long run".

I'm thinking that if after years "nothing happend"... at least the pulley may have welded into the crank. But would be good having an idea of what is that "long run".

Hope more people with issues would post here. Many are concerned only about A/C or steering problems.

I've had mine on for like 20k miles and some are at 20k+ TRACK miles.

There really is NO worry, it's a great mod. Spikuh didn't have it on for long, and IT WAS A CRANKSHAFT or INSTALLER problem. When the OEM one was put on, it wobbled like a SOB. Our cars are internally balanced so there is no issue in running the pulley. And the aluminum didn't effect the cast iron. It must have been manufactured like that.

I will close/delete this thread. It wasn't originally intended to spread a bad word about them. God knows how it was bumped after a year+
