You have to see this! http://www.presspley.com/F1/video/Presspley%20F1%20Fireup.mpg Infos on the video: "At the end of the season, the teams have a competition to see who can generate the highest RPM or simply to create the most light and noise. The car is sitting on stands and is "fired up" or started by an engineer on a laptop. He has a throttle control in his hand (called a pit pedal, basically looks like a controller for a Scalextrix toy car) and he can rev the car in anywany he wants. First the engine is warmed up and the exhausts begin to glow red then white hot. The exhaust do not have any mufflers unlike your standard road car so the noise is deafening. The flames are from the unburnt fuel that gets ignited by the red hot exhausts!"
