At one of the Porsche club events I happened to be in front of a Carrera GT on a road tour. On one straight I deliberately slowed down so he would pass, and I got to hear the GT pass me. It was great, and he manged to pass quickly.
Everyone should go to a top fuel funny car drag race at least once to hear and feel (through hearing protection) the sound of a sub 3 second 300+ MPH 1/4 mile 7,000 HP 1/4 mile run. Not necessarily a nice sound, but it has to be experienced to understand what real power is. Only a large rocket launch is more awesome.
