Rodger, went looking around the web to find more on this. Seems the original article was written around 2003, but there has been some updates since (2012).

Did these inspire those advertisements on TV where people working in an office pull a starter rope to turn on their computer? Prescient.
On youtube, there's a guy who runs 'Visible V8' models up to ~7200 rpm. Not too sure what his goal is, but he'll tell you about melted crankshafts and twisted connecting rods, and teflon topped pistons.

As for wristwatch like complexity on mass produced engines, nothing beat the Napier Sabre British Engine on the Hawker Tempest...24 cylinders sleeve valves H engine...extremely efficient...just as unreliable!

Contrast to the unsinkable Pratt and Whitney R-2800's power and simplicity running the P-47(one kept flying after taking 3,000 hits!) One bullet was enough to kill the Tempest...just like with the Mustang!

The 18 cylinders 3,000hp PW engine itself(without gearbox and rear accessories) was only 2.5 feet long! - 4/7/13, 1:59 PM
