Well, in theory you cannot lose the weight of the motor, tranny, rear end and tires. So the max you could go down to would be 3000 to about 1000. LOL

Yes but I forgot to tell you that the race track surface was covered in super magnetic material and the engine, trans and rear end were cast iron.....in this case they would be weightless!!! Some trains run on these super magnets!!
