For those that don't know Ken Block...

Yeah he did a stint on Top Gear and ramped the car, was so sick. He's in the DC snowboarding vid ramping the jumps on the piste with the boarders. The guy is amazing. His little 4 cylinder Ford is limited to 650 hp at the rear wheels for traction but it makes 850 in total. I love the crack -pop of those engines. I have always wondered about the fire bursts out of the exhausts-anyone know why it happens and why those engines crack and pop??
