The snout of the pulley just split apart and had starting to cut into the front where the EGR piping is in front of the pulley, The scary part is that pulley had less then 2500 miles because I havent been driving my car as much lately.
Hopefully, your experience here will make it clear to others why it is SO important to inspect aftermarket supercharger pulleys regularly. So many of them fail sooner or later.
The crank pulley is good way to go. (I like the 181, but a 178 is great choice too). The last ASP kit I installed (2 weeks ago) seemed to have slightly undersized bolt holes on the Waterpump pulley (I checked an older ASP WP pulley I had on hand and they were drilled to approx .257" ... this one was closer to .238" making it hard to re-install the 4 bolts .... I drilled them out to .250" and it went together nicely).
If you are using the kit that comes with a 60mm smooth idler (replacing the factory 90mm idler) ... check this pulley for loss of lube (and chatter) periodically, I have yet to see one last longer than 30,000 miles before it came apart shooting the pulley into the underpan (and of course the belt come off ... no power steering , no alt , no water pump .... ) . If you are using the kit that comes with a Needswings PSK , it comes with a more suitable idler, so you should not have to worry about this issue.
