Reply to comment by actfatcat in SpaceX on Twitter: Super Heavy Booster 7 completed a full duration static fire test of 31 Raptor engines, producing 7.9 million lbf of thrust (~3,600 metric tons) – less than half of the booster’s capability by allforspace

S-IC nominal burn time is 150 seconds, or exactly 2.5 minutes.

Superheavy nominal burn time is 169 seconds, or 2.8 minutes.

Though that figure may have been for the 29 engine version, the 33 engine version might be a bit less since it burns fuel quicker.

Either way, it's close enough to the Saturn V that I think it's fair to call it a 'similar' duration.
