My bad. It seems the way the story is written is that he checked it on the side of the road.

 

Also it seems that since his supercharger failed it could have been a defect from the factory, user install error, or as he said the heated the hub with a torch caused the seal to fail.

This has nothing to do with a 19% pulley since if his charger was leaking oil it would have happened with any pulley.



Just as a reference I have seen a bunch of pulley installs and a toaster over works just fine :smile:

 

Randy also mentioned something this past weekend about cavitation on a 19% pulley in the water-pump?

Personally, I think the 15% (for bullet-proofness) or 17% (For the better edge)
are the way to go. but, if ya gotta push the limit :smile: 19%

 

i believe this was an original concern of all of the smaller pulleys but it has shown to not be an issue with smaller pulleys up to and including 19%.
