If this isnt enough for you then... lets get into the estimated calculations:
Estimated Sustained Turn Time, No Flaps
Notes:
Take Off: 1650hp --- Very Short Duration
Nominal: 1500hp at SL / 1550hp at 1200m / 1450hp at 3800m - Continuous Power
Combat: 1600hp at SL / 1650hp at 1800m / 1500hp at 4500m - 30 Min Regime *
* Soviet pilots were told not to use it unless they had to, this is because even if the power is safe to use for 30 minutes, it reduced the engine life to only 25 hours.
