Using RPM for speed

suprabahamut · 06-18-2008, 02:17 PM

If this will work, my speedometer cable is broken. Is there a way to use RPM for MPH? If so if anyone has some free time. Find out what RPM the engine is in with the transmission in 4th or 5th gear for 35, 40, 45, 50, 55, 60, and 65, I would greatly appreciate it. and 25 in 2nd or 3rd, or 4th for school zones. Is this possible, I know the gears are set ratios, so hopefully it works. Any information, or websites just please put up. I will be able to get the cable in a while but not for 3 months probably. I am still checking scrap yards.
