My dash speedo is not accurate and I stuck my Garmin GPS on the windshield and selected the trip screen. It worked great. It also shows your max speed. It really is amazing how quickly these Cobras get to 100 MPH! I have plans to replace the speedo cable this winter. My gearing is pretty simple in 5th. 2,000 RPM is 55 MPH, then every 200 RPMs is another 5 MPH, making 2,600 RPM about 70 MPH.
