The GE90-115b is rated at 513 kN maximum thrust and is often said to have 110,000 shaft horsepower, but I have yet to find any document or specification that backs the claim on horsepower figure. Initially the GE90 was only one of three 777 options and GE Aviation then-CEO Brian H. Rowe would have paid for the development of putting it on an A330, but Airbus' strategy for long-haul was the four-engine A340, missing the market favouring twins. It features a new, improved life high pressure turbine and an advanced FADEC. This condition, if not corrected, could result in additional IFSDs of one or more engines, loss of thrust control, and damage to the airplane. The fan/LPC is driven by a 6-stage low-pressure turbine. The 777-300ER is the Extended Range version of the 777-300 and contains many enhanced modifications including the GE90-115B engine, which is the world's most powerful jet engine producing 115,300 lbf (513 kN) thrust .
