Wow, these are indeed some big big big engines. In fact, each of them is the largest production engine of its kind.
For example, the 2294cc Triumph Rocket 3 engine is the biggest production motorcycle engine on the planet. The GE90-115B jumbo jet engine is the world’s largest turbofan engine tipping the scales at 8300 kg. The longest steam locomotive engine is called the Big Boy, and boy is it ever big with a total locomotive length of more than 85 feet.
The F-1 Rocket Engine is simply amazing. The footage of this engine igniting at the 3:09 is INCREDIBLE! By the way, there is indeed some crazy great engine sound on this video!
