That brings back some memories. My cousin had a Hillman Minx that he had installed a vacuum operated "Wolf Whistle" on. Thing sucked so much vacuum from that underpowered engine that it would almost stall the motor. I remember chasing some girls in another car and every time we would catch them and he would turn on the wolf whistle, it would knock 10 to 15 mph of the Hillman's speed. Crazy teenagers!
