Haven't seen the movie but i was at Magny Cours where the CS picture was taken. The 430's and the CS's have those blue flames for the whole time they are being 'floored' in gear. As such, duration is longer than a quick flash from a normal backfire.

 

me too

 

A couple of my old IMSA shots.

This may be a stupid question, but what causes the sparks? Is it just from part of the car making contact with the ground under braking or other conditions?

 

Are you refering to what is causing the actual flame? If that is what your asking, when you take a volotile liquid, such as high octane race gas, or even regular gas and you put it in an enviroment that is extremeley hot in the presence of oxygen you will get combustion. When you see a race car or a regular car pitching a flame out the exhaust it is due to unburnt fuel exiting the exhaust system, when it reaches the terminating end of the pipe it is introduced to the oxygen and ignites. Street cars will almost never do this because they have catalytic converters that are designed to burn up any left over fuel before it reaches the tailpipe. In fact, you can bet that if you see a street car doing this and it is a newer vehicle, you can bet they do not have a cat.

 

Thank you very much for the explanation, but actually I already understood what caused engine backfires. My question was, what causes the sparks that are seen in some of the pictures (mostly the ones of F1 cars)?
