[s-cars] NAC, but F1 tom foolery nonetheless...

Pulled from a post on the Boxster Racing Board - this is seriously cool!
Load the link and press play. First you?ll hear a 10-cylinder, 750
horsepower Asiatech F1 engine being warmed up. Then it performs a rousing
version of ?When The Saints Come Marching In?, to the delight of assembled
pit staff and journalists.

Here?s how the magic was achieved (technical/musical details via F1 Racing
magazine):
As we all know, a V10 engine produces five combustions per revolution at a
frequency per second of 60/(5 x revs per minute), which equals 12/rpm.
Therefore, to work out the revs you need to hit a particular musical note,
you multiply the note?s frequency by 12.
To play a 440Hz ?A?, for example, you need 5,280rpm. For ?C?, use 3,139rpm,
for ?F? 4,191rpm, and so on.
Asiatech?s French technicians (the engine, despite its name, is derived from
a Peugeot design) simply programmed their engine to run
through the various rev/note ranges in the correct sequence
