Yes. The height of the ramp does affect the speed going down it the higher the ramp the faster the car goes down it
Wind speed may affect cars, effect change to aspects of cars or have an effect upon cars but, to say that wind speed effects cars is most likely a typo. I recommend changing the question.
The car's mass should have no effect on that speed.
Yes, and I saw the result of that while living in Germany. Two cars hit headon going at the same speed. It was a mess. One was a VW Beetle and there was nothing left but the back seat. They had to airlift the driver out.
It's used for the speedometer and the cars ECU (computer). It tells both how fast your going.
All tires have a speed rating, driving above is "Highly Not Recommended" as the tire can/will come apart due to heat build up. There where cars limited in speed due to this reason.
Because a higher ramp gives more potential energy than a shorter one.

Friction and Gravitational forces
A GATSO speed camera
by moving it
yes it's true
Faster than other cars
they restrict the amount of air and fuel going into the engine
140 mph

There are a variation of things that affect the limit of a cars speed, primarily the horsepower and torque ratings of the car, in comparison to the weight of the car, but even with high ratings in comparison to weight, most cars also have a governing chip in the computer system, that shuts of the valves at a certain designated speed. I hope this answers your question.
