From the driver:

140 psi boost and 125 psi drive. TOO MUCH LOAD FOR THRUST ON SMALL TURBO... All else seems fine so far will look into it more tomorrow. Days like that one ya miss a slick track with less bite. lol O well what ya gonna do? But thats what 4900 rpm in 3rd gear sounds like. Just FYI

That's because in most sanctioned pulling events, you have to have 2 bolts that form an X going through the exhaust pipe within 6 inches of the turbo outlet to prevent that.

What you usually find is pieces in the bottom of the intercooler and a nice spiral cut where the turbine wheel exits the turbo.
