Top speed is definitely dependent upon horsepower. Horsepower is torque x rpm.
Top speed occurs when the force propelling the car equals the drag and frictional forces acting on the car. The force propelling the car is proportional to how much torque the engine is putting out. Multiply your torque by your engine rpm and once again that is horsepower.
As for a Civic DX doing 130mph in less than 30sec from a standstill, that is a joke. I'd bet it takes my '00GT almost that long to hit 130. I would be willing to bet that a stock DX would be hard pressed to hit 100mph in less than 20sec, so how is it supposed to hit 130 in 10sec after that? I don't know if you've ever read any acceleration test results when they keep going past the 1/4 mile, but things slow down alot. Down forget that the wind resistance increases as the square of the speed.
