I used my GPS set in KM/HR mode and switched my Si to read KM/HR and found out that my car reads about 1.5KM/HR slow at 103 KM/HR (more accurate since KM is a smaller unit than MI. Then using my ScanGaugeII I adjusted my speed to read 3000 RPM and that's right at 69 MPH true speed. That's roughly 43.5 RPM/MPH so 40 MPH in 6th = 1740 RPM and 50 MPH in 6th = 2175 RPM. If you asked this question about my auto tranny CR-V I'd say "I dunno" since the slush box won't lock up and provide a fixed ratio until you're going nearly highway speeds.
