That may be mine someday. Already planning on a built motor and more boost. Awesome pics. How many rpms when she let go. Whats the highest rpm's you have ever turned it?

So no reason for it letting go?? What kind of mileage did you have on it at the ime of the carnage?? Makes me worry about my 2007, but I still have warranty on my engine and tranny I think.

I wouldn't worry to much. Failures are rare. With a millon or more of these on the road theres bound to be a few let go. I'm running 9.5 psi of boost. I know of many running 12psi. All on stock internals.
