found this surfing youtube today. Its a sound file of the BRM V16 F1 car, a crazy ass F1 car from the 1950s that I had previously never heard of. Far too insane to be remotely reliable during the 1950's, but sounds terrifying when its working. And 5.7 BAR of boost = holy shit.

http://en.wikipedia.org/wiki/British_Racing_Motors_V16They really need to take the rules off of racing again aside from something like displacement, so crazy shit like this and group B rally can happen again, and the resulting epicness/carnage can be recorded in stunning high definition.
