The Boeing 777's twin-jet engines equal 175,000 horsepower. With this, our pilots can make this aircraft accelerate from 0 to 96 km/h in just 6 seconds. That's why the engine is listed as the most powerful jet engine in the Guinness Book of Records.

The most recent derivative of the GE90, the GE90-115B, is the sole powerplant for Boeing's longer-range 777-300ER and 777-200LR aircraft. The GE90-115B certified at 115,000 lbs. of thrust and has broken a number of aviation records.
Why doesn't a Boeing 777 have 4 engines instead of 2? . Because four turbofan-engines equates to twice as much maintenance-and-repair as two turbofan-engines . They also contain twice as many failure-points , thus engendering twice as many costly aircraft breakdowns .
We have made it clear that the Boeing 777 can actually fly with one engine without much trouble. Whether it is fuel starvation, the fan blades, or any mechanical failure causing the engine to fail, if any of the jet engines fail, the remaining engine can help the plane fly safely.
Boeing opted for a clean-sheet design for the 777 but stuck to a twin-engine configuration. The main reasons for this were the recent 757 and 767 models' success, lower cost for engine development, and an overall lower program price tag.
What makes the plane so expensive? The 777-300ER can carry 365 passengers compared with the 787-9's capacity of 280. The GE engines on the 777 model develop 62% more thrust than the 787's two engines. The plane is also longer than the Dreamliner, has a greater wingspan and a greater wing area, and is taller.
A B777 typically consumes 8 tons of fuel per hour. So with 35 minutes left to the flight, we can assume that the fuel dumping procedure took approximately 5 minutes to dump all the fuel.

The trijet 777 was later dropped, following marketing studies that favored the 757 and 767 variants. Boeing was left with a size and range gap in its product line between the 767-300ER and the 747-400.
