Black Mustang Speed Demon???
 

Just picked up a Black Mustang, after buying a friend a gold civic. While I haven't tried racing it yet, the Black Mustang noticeably beat my original Zip into the dirt. Both cars I tested were using green gears and had no body. They both ran on a smooth 5.5ft surface.

Results:
Original using NOS, Mustang using TURBO
Mustang finishes far ahead in multiple trials.
