On the dyno today my s366 stopped boosting, comes out the shaft has broken in half, no surge, we ran 33 psi boost, gave no signs of failure until it seized. It seems that the turbine side is stuck, I can move the comp wheel by hand it has minimal damage. Will tear is down to see it all but it is very disappointing, have not covered more than 6k miles on it!

 

Ok. time to call BEP about it, and see about repair costs.. And no, it won't be warrantied, nor a free repair.

 

agreed...call them, box it up, send it in. They generally inspect turbos promptly and will find the cause
