So recently had a catastrophic engine failure on track. This was my first time at a new track (Collie Motorplex) which is a longer track than where I usually run with long periods of wide-open throttle. We were running 5 lap sessions (1 warm up, 3 hot, 1 cooldown). The failure occurred right at the end of the 3rd hot lap on the 2nd session of the day. Engine was at 7500 rpm in third gear when it let go.
Managed to get of the track before I dropped any oil and ruined someone else’s day. Nothing to do other than get the motor out and try and determine the root cause of the failure.
