nony, thats true for some but as you know first hand, some manufacturers turbine engine cans are designed quite differently than others. Some manufacturers can designs indeed actually perform and run substantially cooler while still operating with fast acceleration/deceleration time, if the design of burner can and its combustion/burn pattern are throughly developed tested and optimized this should allow further and safe acceleration increase without additional or any detrimental ware of course... eg- 2.5 sec, idle 33k - max 126k for our TJT-3000 engines.
