I was just watching Miami Vice and must say I love the F430 scene, http://youtube.com/watch?v=oVfBreSgfAM I was wondering how/why the blue colour of exhaust is formed, does this occur with a straight exhaust at high RPM's? I've also seen this effect a video with a Lamborghini Gallardo. http://youtube.com/watch?v=tFuso6JfWQs
this was talked about a bit in this thread http://www.ferrarichat.com/forum/showthread.php?t=115260&highlight=miami+vice+blue+flame&page=5 it can happen under hard acceleration. also, a nice video here of the same effect: http://video.google.com/videoplay?docid=5373048045577562020 GT
