I think Bart impulse Allen is the fastest speedster. The fastest man alive is Barry Allen because he is the speed force. Though many debate it is Wally West because he had a better understanding of the speed force but that was only because Barry was dead and stuck in the speed force.
Kingda Ka is the fastest roller coaster in the United States. It was the fastest coaster in the world for a few years but has since been eclipsed. (It is still the tallest, however.) It's similar to Top Thrill Dragster (although faster), but it feels rougher. If speed is what you are after, Kingda Ka delivers.
