i know that was done many times but let do it again. lol
i had some problems with my speedomater being off by 10mph ,after it corrected it self thats what im getting on 94LS coupe 66K Auto

about 14500rpm->45mph
1500rpm ->50mph
2000rpm -> 60mph
3000 rpm -> 80mph

My friend "Pirate" that just got his 95L coupe wiht 38K Auto

from an earlier post:

---------------5spd-----L/LS------GS-------6spd
1st-----------2.937----2.476----2.458----2.937
2nd----------1.692----1.451----1.454----1.692
3rd-----------1.060----0.973----0.948----1.151
4th-----------0.769----0.630----0.630----0.868
5th-----------0.581-----------------------0.682
6th---------------------------------------0.521
reverse-----3.185----1.809----1.826------3.186
final drive---4.491----4.370----4.787------4.491

(mph/60) x (tire rotations per mile) x (gear ratio) x (final drive) = rpm

For a 215/55 tire on the 16" GS wheel, ~797.159 rotations per mile.

Sean.C i did the math i have 225/55/16
(60/60)x(783)x(.630)x(4.370)=2155 rpm's at 60mph so im abot right
im low about 155 rpm's on each speed i post it above.
