The lecturers wouldn't let anybody sit in the boot because they knew just how lively she was gonna be.

This was just a quick power run after class, so we didn't bother setting it up properly. The tune was literally a week old so I was confident about the mixtures and such.

Pulled just under 1250Nm of torque
