the other day a roush stang (didnt look like much of one but i saw the roush supercharger emblem on it) pulled up next to me and he started horsing around. Traffic was pretty heavy so I wasn't in the mood to play but anyhow he stepped on it real hard and went by me just to come up on a red light and he must have down shifted to 1st gear sounded like his car was gonna explode. then i saw smoke start coming out the tail pipes. Did he screw something up or is that something thats not that uncommon when your beating it up?
