DRAG allows the user to design his own dragster and then race it against a dragster designed by another player or the computer. you must specify the horsepower, rear end ratio, tire width, and tire diameter. There are no limits to these parameters.
Aha! you say. "I'll just design a two million horsepower dragster!" But it doesn't work that way, because your mass is related to your engine size, and so you usually end up with a top speed of something like 33 MPH. The computer is extremely hard to beat, but it's rumored that it can be done. Note: on some systems the amount of time between printouts can be aggravatingly long.
