The throttle position showed 36% opening and not 100% opening when the engine failed, this would indicate that the engine most likely was in a deceleration mode. Active suspects a driver mis-shift going from 4th to 5th gear and hitting 3rd by mistake. Why? Because the road speed at the time with the 36% throttle opening indicated a 207 KM/hr speed (128 MPH). If the supercharger created excessive load on the engine to break the connecting rod, the shadow memory would most likely indicate that the throttle would be closer to 100% opening where the maximum supercharged power is developed.

When was the maximum engine speed recorded? Just prior to the "event"?
If I'm reading this correctly, you think he missed an upshift from 4th to 5th and downshifted to 3rd instead? He would have had to be near redline in 4th at full throttle, attempting to bang it into 5th, but instead slipped it into 3rd, dumped the clutch, and dropped the hammer. Forget 8700, wouldn't that have broken the damn needle of the gauge?
You wrote 8705+, what does that mean exactly? How long was the car at 36% throttle? An instant during the shift?
