Following the successful introduction of the EGT Typhoon at a power rating of 4100 kW (5500 hp), planned enhancements have been introduced to increase the power to 4790 kW (6400 hp). The changes to meet the higher power requirement include an increase in rotational speed by 5% with resulting increases in mass flow and pressure ratio, thermal barrier coating of the combustion chambers, and the directional solidification of the hp rotor blade material.

The design changes are described along with the validation by rig work and engine running, building on the extensive field running of engines at the 4100 kW rating.
