hoping there's an easy way to incorporate the speed effect

Overly detailed reason why:

Simpler:
I put a playerbot on a map skinned with The Flash's look (DC Comics character). Altering the bot's movement settings I've given him as close to a superspeed ability without making him impossible to beat, just damned hard to hit.

Does anyone remember Relics? It put power items all over any given map that gave users powers, after a fashion. The person that picked up the speed relic moved really fast and got this after image effect behind him as he/she ran.

How does one get that speed effect? I've skimmed the relics.u and can't figure it out.
