Re: SpaceX are working on a bigger engine also
If the raptor engine goes really fast, will it be a Veloci-raptor?
Nah. A Velo-sea Raptor is what happens if they strap one onto the back of a bicycle, put it on the beach pointing toward the ocean, and then light the fuse.
"Look ma, no pedals! Wheeeee!"
(I'm sure that was one of the tests they were going to do, right?)
