I definitely would have run away. I nearly ran away when my own car was put through it's paces on a chassis dyno. It's just not normal to hear a car make that kind of noise and be stationary!

jamin - I believe flames often normal on overrun from big revs with a turbo, often there is a system to inject fuel into the exhaust on the overrun to keep the turbo spinning. I also suspect there were some open headers under that car.
