[OT, yet neato] hear an engine sing

let's see, our VW's have 2 combustions per revolution I think, so at 60(2xrevs) to produce a 440hz "A" our engines would have to be at 13,200rpm!!! If the link didn't work before try this one: http://astro.temple.edu/~kmr/Chauffe2.mp3
and if it STILL doesn't work copy and paste it in your browser window, it should work then.
