It is entirely possible that the motors have a free speed of 16,000 at 12 volts.

The only thing I am basing my number on is a print from Mabuchi (they are a significant supplier to Delphi, so I have folks to ask for such things).

Anyway, the print says 15,000 rpm free speed, but that doesn't mean that every single motor will run exactly at that nominal value. I would not be surprised to learn that the motors vary up and down 10% which would mean that the 15,000 rpm could be as low as 13,000 rpm and as high as 16,500 rpm.
