In the mountains of central Asia, yak racing is a hairier, but no less entertaining twist on horse racing. It's kind of like building and running the world's fastest naturally-aspirated SRT8 Jeep.

Built by Lewis Performance Machine, this rear-drive-converted SRT8 Grand Cherokee has a stroked 440ci motor and it runs 10.5 @ 125mph. It might not be quite as fast as the low-weight leaders (or twin turbo SRT8s), but it's just as fun to watch.
