What's the top speed on your car?

Guys, Guys , guys
How long ahs it been since you guys took physics? In reply to Jimberg, gravity puls every object down at the same speed, NO EXEPTIONS!!!!!!!! Secondly mass has so much to do with top speed, it is not even funny. Example: a 250 hp engine can propel a 3000lb car to a speed of lets say 140miles. Now the same 250hp engine will propel a 3500 lb car to only 135miles. My rig is capable of 90 miles per hour top speed when loaded with 10 000 pounds. When I got 30 000 lb on the back of my trailer, my top speed is only 80 miles. Aerodynamics along with wieght are very important when dealing with top speed. You will never run as fast with a 50lb bag on your back as you would without it. Porche is fast because it is relatively light, but most of all it has very low wind resistance. So pull up those old physics books and review the formulas. Horsepower is also calculated bases on the vehicle weight and the time it takes to travel a certain distance. Hope I put your minds at rest.
