BTW using my GPS for accurate MPH. when I compare that to speedo, speedo is about 3-4mph slower at 70+. I am sure there is "some" growth in the circumference of the tire due to heat and centripetal(sp?) force. Never could get that and centrifical force straight.
Also everyone, there is a way to mitigate the rpm drop from an aluminum flywheel within the calibration. Its a very crude version of
Rev-Match utilizing what's called the Throttle Follower.
