There are superchargers for the 2 stroke car motors, but they are mostly for show, not go! If you just want to bling something out to be different, go ahead and waste the $$ on one. I've seen the O.S. 4 strokes in a 10th scale on road touring car, and while it was fast, it couldn't hang with the 2 strokes...but it did use about half the fuel. He didn't have to refuel but once near the end of a 15 minute main.
