I didn't have any good audio software on the computer and resorted to matching frequency by using this tone synthesizer http://www.philtulga.com/tone.html. Obviously Audacity is much more accurate with clear audio... I expected to be within ~5-10 Hz based on matching a few other cars really well.

I have a new appreciation for hitting the rev limiter on the dyno. We need someone to get out there with a good mic and radar gun
Just to be clear: I meant matching the audible frequency, not necessarily peak rpms (and especially so in the case of a moving car)
