What makes this even more impressive is that the rules restricted the boost to 1.1 bar and they had to run the cars heavy. The boost levels where logged for the entire event and any spike over 1.1 meant disqualification so they ran 1.05 bar.
They ran std brakes which were glowing red by lap 3. It's a tough track anything you have seen on TV doesn't show how tricky this mountain is. If you ever come to Sydney its a couple of hours drive to the track which is an open road on non race days and you can drive it at normal speeds all day if you want.
