SVT crank, Eagle rods, and Probe pistons (~9.2:1 CR w/SVT head).

I ran the undampened 5.7" crank pulley - IMO that had a big factor in the rod bolt failure ... classic overloaded (not over/under torqued) tensile failure.

Engine ran fine for my daily commute a week prior to the event, ~6 passes down the dragstrip, the drive to Mid-Ohio, and three 20-min NASA TT heats. Could feel the engine starting let go in the 4th TT heat near the end of the big straight (sustained high RPM) but managed to hold together around the track until turn #1 (just past the pits of course).
