Nitro is 2.3 times as energetic as gasoline. Consider that a gallon of gas powers a 3000 pound car as much as 50 miles, and nitro would move would move that same car 115 miles. that means a cup would make it move about 15 miles. Try pushing a 3000 pound car that far, and you'll appreciate a cup of nitro
An ounce would move that car about a mile. At speed. http://en.wikipedia.org/wiki/Nitromethane
