The rules changes in dragracing. You run max everything, since the race is 2 seconds or less for the fast cars. As you can see Max motor RPM is never reached. It becomes rotations per second.

If they are getting 100mph out of a MM motor on 4s I'm sure they are getting the rpms up past the max rated limit. The motors wont last long that way, and im sure they are pushing them past their rated limits for very short bursts. Not a good idea for general use for sure. They are just taking their chances that the motors can handle it for a short burst. I'm sure that more than a few of them have blown the motors, escs or both by doing it as well.

The risks are no different then the real thing except that no one is riding in the vehicle that could get injured or killed. They tear down their systems after every run to get them rebuilt for the next pass. They are pushing those systems way past their rated specs to acheive the goal of going very very very fast. I know that I would risk the electronics even if I could only do one run over 100mph just for the experience. Of course everyone hopes that it will not go up in flames, but that is the risk you take to acheive those kinds of speeds. You only life once right???
